Milestone 2 of 5: Where a chart comes from
Where a Chart Comes From
What every conclusion you will ever draw actually rests on — birth time, ayanāṁśa, and latitude.
Assumes you have done: Week 2 unit 1
Why this matters
This is the chapter people skip, and skipping it is why so much practical Jyotish is confidently wrong. Chapter 5 shows you how a chart was built before software, by hand, from an almanac — and in doing so it shows you exactly which three inputs everything depends on. In Week 10 you will be asked how finely it is honest to divide time into periods. The answer to that question is in this chapter, eight weeks early.
Learn
There is a version of this course that skips Chapter 5. It would save an hour and cost more than any other hour saved in the whole book.
Parashara is showing you how to build a chart by hand from an almanac: how to find the Moon’s position by interpolating between nakshatra boundaries, how to convert equatorial rising times to your own latitude using a shadow measured at noon, how to derive the ascendant and then the tenth house and then the intermediate cusps. It is careful, it is clever, and you will never do it.
What you will do, constantly, is depend on the three things it reveals.
The ayanāṁśa
At verse 14 the ayanāṁśa appears: ayanāṁśa added to the Sun’s position gives the Sāyana Sun.
There are two zodiacs. One is measured from the vernal equinox — the point where the Sun crosses the celestial equator in spring. The other is measured against the fixed stars. They were aligned once, around the third century, and they have been drifting apart ever since, because the equinox slowly moves backwards against the stars at about fifty seconds of arc a year.
The gap between them is the ayanāṁśa. Today it is about twenty-four degrees — most of a sign.
Jyotish uses the sidereal zodiac. Western astrology uses the tropical one. That is the whole of why someone is a Pisces in one system and an Aquarius in the other, and it is not a disagreement about where the Sun is. Both are right; they are counting from different zeroes.
Latitude
Then a long stretch on Laṅkodaya and Svodaya — rising times at the equator, converted to rising times where you actually are, using the length of a noon shadow to establish your latitude.
The underlying fact is geometric. The ecliptic crosses the horizon at an angle that depends on where you stand. At the equator all twelve signs rise in roughly two hours each. Move north and the symmetry breaks: some signs rise in forty minutes, others take four hours.
Two consequences, both practical.
First, planetary longitudes are the same for everyone on earth at a given instant. The Moon is where the Moon is. Second, the ascendant is not — it depends on both when and where. That is why birth place is asked for, and why a chart without one is not a chart.
The birth time, and what it is really worth
This is the part to carry out of the chapter.
The whole of the ascendant calculation runs off Iṣṭa Kāla, the time elapsed since sunrise. Everything downstream inherits its error.
The ascendant covers 360 degrees in about twenty-four hours. That is roughly a degree every four minutes.
So: a birth time recorded to the minute gives you a Lagna good to a quarter of a degree. Recorded to the nearest five minutes, good to a degree or so. To the nearest hour, and you have a fifteen-degree band — half a sign.
The rising sign usually survives all of that. What does not survive is everything that depends on the Lagna’s degree: the Bhāva cusps, several of the finer divisional charts, and any timing technique subtle enough to care.
What honest practice looks like
Nothing here should make you fatalistic. It should make you specific.
Write down where a birth time came from. A certificate is not a family memory is not a rounded “about ten in the morning”. Then, when you draw a conclusion, know which category it falls into: does this rest on the rising sign, which is robust, or on the Lagna degree, which may not be?
The course’s own charts are set up to make this visible. DiCaprio’s time comes from a birth certificate and is recorded to the minute, which is why he is the chart used for timing work. Einstein’s certificate records “before noon at eleven and a half” — a genuine document, and a statement to the half hour. His Lagna sign is entirely secure; his Lagna degree is good to a few degrees and no better. Both facts are printed on the chart page, and neither is embarrassing. They are simply what is true, and saying what is true about your inputs is the first discipline of the whole subject.

This is the source itself. The teaching above prepares you for it; it does not replace it.
पञ्चाङ्गस्थो मिश्रमानकाल: पङ्क्तिसमाह्वयः ।
सूर्योदयाद्यातकालः सावनेष्ट उदीरितः ॥ १ ॥
- The 'Mishramaankaala' in the almanac is called 'Pankti'. The time from the sunrise to the desired time is called 'Savanesta Kaala'.

2-4 The difference between the two Kaalas (Sawaneshta and Mishra Kaala) in terms of day etc. (that is day, Ghati, Pala etc.) is called Yaata kaala or Aishya kaala. If the Pankti kaala is ahead of the Ishta Kaala (that is, if the clarification of the planets is to be made before the Pankti kaala) then Ishta Kaala is to be deducted from the Pankti Kaala. The remainder in day, Ghati etc. will be called negative or Yaata Sanjaka. If the Ishta Kaala is ahead of the Pankti kaala (that is if the situation of the planets at the time of birth is to be known) then Pankti kaala is to be deducted from Ishta kaala and the remainder in day, Ghati etc. will be called positive or Aishya. The resultant negative positive in day, ghati etc. is multiplied by the movement of their respective planets. The figure so arrived at is divided by 60 and the degree etc. obtained in this way is to be made negative or positive in the planets of the Pankti kaala. In Yaata (Rahu and Ketu) and in retrograde planets the process is reversed and is made positive negative. Then the planets of that time will be clear.
Notes: In the old almanacs the planetary position was given of midnight each after eight days. This is called Pankti. Some Astrologers call it Prastaar also. Along with planetary positions the planetary movement is also given.
The difference between the Ishta Kaala and Mishra Kaala is called Chaalana. This Chaalana is either Aishya (+) or Yaata (-). If the Ishta Kaala is of time before the Mishra Kaala, then the Chaalana is negative (Yaata Sanjaka); and if the Ishta Kaala is of the time after the Mishra Kaala, then the Chaalana is positive (Aishya Sanjaka); because if the Ishta Kaala is of the time before the Mishra Kaala, then the planetary position of the Ishta Kaala will be arrived at by deducting from the planets of the Pankti Kaala; and if it is of the time after the Mishra Kaala then the planetary position of the Ishta Kaala will be arrived at by adding in the planets of Pankti Kaala. But in the case of the retrograde planets the process is reversed.
In the almanacs the Pankti of the Mishra maana Kaala is given in the following manner.
The Ishta of Planets on 8 (Ashtami) Monday 28-5-1951. Mishramaana Kala 47-04
| Sun | Mars | Mer. | Jup. | Ven. | Sat | Rahu | Ketu |
| 01 | 01 | 00 | 11 | 02 | 05 | 10 | 04 |

Suppose the birth of the native occurred on Jyeshta Krishna Trayodashi Samvata 2008. Date of birth 2-6-1951, Place of birth Hapur. The Sawaneshta or Ishta Kaala of the time of birth is 44 Ghati, 32 Pala and 20 Vipala. The day number of Saturday is Seven. Therefore, the Ishta Kaala may be called 7-44-32-20 day, Ghati etc. Pankti is of Monday dated 28-5-1951. Therefore, the Ishta Kaala of the Planets of Pankti will be 2-47-04 day ghati deducted from Ishta Kaala: The remainder will be called positive or Aishya. It is also called positive chaalana.
| Vaar (day) | ghati | Pala | Vipala | ||||
| 7 | − | 44 | − | 32 | − | 20 | |
| (−) | 2 | − | 47 | − | 04 | − | 0 |
| 4 | − | 57 | − | 28 | − | 20 |
Aishya or Positive Chaalana
Now in order to know the Planetary position at the time of birth, first of all the positive Chaalana is multiplied by the motion of the planet. The resultant is added to the planet position of the Pankti Kaala. Suppose the motion of he Sun is 57'-18" and the position of the Sun in the Pankti Kaala is 1-13°-24-36"
Therefore (4-57-28-20) 57-18+1-13°-24'-36" = 1-18°-8'-12" will be the position of the Sun at the time of birth. In this way the position of all the planets will be known. In the case of the retrograde planets the multiplication of the Positive Chaalana and the movement of the planet is deducted from the movement of the planet of the Pankti Kaala.

5-6 Bhayaata Bhabhoga Sadhana. When the Ishta is more. and the Nakshtra is less.
If the Ghati, Pala etc. of the Nakshtra the day of the birth are deducted from the Ishta, it is Bhayaata and when the Ghati, Pala etc. of the Nakshtra of the day are deducted from 60 and when the Ghati, pala etc. of the present Nakshtra are added to it, then it is Bhabhoga.
When the Ishta is less and the Nakshtra is more.
When the Ghati, Pala etc. of the Nakshtra of the day are deducted from 60 and the Ishta is added to it, then it is Bhayaata. And when the Ghati, Pala etc of the Nakshtra of the time of the Ishta are added to it (i.e. 60) then it is Bhabhoga.
**अथ चन्द्रस्पष्टमाह**

7-8 Knowing the position of the Moon: Bhayaata is multiplied by 60 and the Quotient is divided by Bhabhoga. The figure so arrived at is added to the Number of the passed Ashwini etc. Nakshtra multiplied by 60. Now this amount multiplied by and divided by 9 (the figure will be in degrees is divided by 30). The figure so arrived at will give us the position of the Moon (Chandra spashta) in Signs, degrees, minutes and seconds.
Notes: The value of Bhayaata and Bhabhoga is in Ghatis and Palas. It has become clear form the above slokas. In order to know the Chandra Spashta (the positon of the Moon), first of all Bhayaata and Bhabhoga are made of similar denomination or they are converted into Pala or Vipala. Then the Palas of Bhayaata are multiplied by 60. Bhayaata multiplied by 60 is to be divided by Bhabhoga. From the division the resultant is taken upto 3 points. The number of the Nakshtra before the Nakshtra whose Bhayaata and Bhabhoga is to be known is found out. This number will be known when we count the number in order from the Ashwini Nakshtra onwards. This number is multiplied by 60 and the multiplied figure is added to the acquired number. The summation (total) is doubled and is divided by 9. The resultant will be got in degrees, minutes and seconds. The degrees are divided by 30. It will give us the positon of the Moon in signs, degrees, minutes and seconds.
We have Bhayaata in Palas and vipalas. Therefore, Bhayaata and Bhabhoga are converted into Vipalas.
Bhayaata (36 palas 20 Vipalas) × 60
= 2180 vipalas
Bhayaata×60Bhabhoga=3 Resultant[(60 ×the number of passed Nakshtra+3 Resultants)]×29
= Moon Position in degrees
2180×60235320=130800235320
= 0 − 33 − 21
The serial no. of the passed Nakshtra Bharani is 2
Every time the remainder is multiplied by 60 and divided by the figure that divides and the quotient is obtained 3 times)
Therefore as per formula:60×2+−33−22×29=241−6−429
= 26° − 47' − 25"
That is 0 − 26° − 47' − 25"
Will be the position of the Moon at the time of the birth
खखशून्याष्टवेदेन गतिर्भभोगभाजिता ।
एवं चन्द्रस्य विज्ञेया रीतिः स्पष्टतरा बुधैः ॥ ९ ॥
- To find out the motion of the Moon: In order to know the motion of the Moon the learned should divide the medium motion of the Moon 48000 by Bhabhoga.
Notes: There are 12 Signs in the 27 Nakshtras.
Sign 12 x 30° = 360° x 60 = 21600 minutes
Because there is 21,600 minutes in 27 Nakshtras
So, one' Nakshtra will have 2160027 = 800 minutes
800 x 60 48000 Seconds
Therefore the medium movement of the Moon is 48000 seconds. If 800 minutes or 48000 seconds have been arrived at in the Bhabhoga from proportion then in the Ahoratra (Day and Night) 60 ghatis it will prove to be the motion of the Moon for one day.
480003922 (Here if 48000 is multiplied by 60, then we shall have the movement of the Moon in minutes and seconds)
48000 × 603922 = 734 Minutes 19 Seconds.

10-11 The Definition of palbha and the finding out of the Charkhanda (ascensional differences) with it: When the Saayana Sun is in the Signs of Aries etc. (that is when day and night are equal) the 12 Angul (fingers) Shadow of Shanku at midday is called Palbha. That Palbha is placed at three places and is multiplied respectively by 10, 8, 10, and the last factor (10) is divided by 3 also, then three Charkhanda respectively are obtained.

12-13. To find out Swodaya from Lankodaya: Place 278, 299 and 323 Palas first in direct order and then in reverse order. The Charkhandas are also placed first in direct order and then in reverse order. First these are deducted from the first three places and then these are added in the 2nd three places. In this way the Swodaya Maana (Swodaya value) of the 6 Signs Aries etc will be in the direct order and of the next six signs Libra etc. will be in the reverse order.

14 18 1/2 Ayanamsha added to spashta surya (Sun's position) is Saayana Surya. The traversed or the remaining degrees etc. of the Saayana Surya are multiplied by the rising value of that sign (the sign in which the Sun is situated) and the resultant figure is divided by 30. The quotient (will be in Palas) is the period traversed (Bhukta Kaala) or the remaining period (Bhogya-Kaala). When the ascendant is found out by means of the to be traversed period (Bhogya Kaala) this period (the to be traversed one) is deducted from the Ghatis and Palas of the Ishta Kaala. From the remainder the rising values (Udayamaanas) of the Aishya signs (the signs ahead of that sign in which there is the Saayana Sun )should be deducted (to the possible point).
When the ascendant is found out by means of the traversed period (Bhukta), the Sawaneshta Kaala is deducted from 60. From the remaining Ghatis and Palas is deducted the traversed period. From the remainder is to be deducted the rising values(Udayamaanas) of the traversed signs or Gata Rashis (the signs before the Saayana Surya). The remainder so arrived at is to be multiplied by 30 and this is divided by Ashuddhodaya-Maana.
The quotient in degrees etc. that is obtained is to be added to the Shuddha Rashi in the Bhogya kind (or to be traversed kind) and is to be deducted in the Bhukta Kind (or traversed kind) from the Ashudh Rashi number. The figure obtained in this way is the Saayana Spashta Lagna. If the Ayanamsha is deducted from it then the figure obtained is Spashta Lagna. If six signs are added to the Spashta Lagna the figure obtained will be the 7th house.

Verse 19½19-19 1/2 If the traversed or the to be traversed period is not deductible from the Ishta kaala, then the Ishta kaala is multiplied by 30 and divided by Swodaya Palas etc. After dividing, the obtained degrees etc. are respectively deducted and added (-- +) from the spashta Surya (the Sun's position), it will give the spashta lagna (or the position of the Ascendant)

Verse 20–21½20-21 1/2 The passed ghatis and the remaining ghatis of the day and the night, whichever is less is called the unnata kaala. The unnata kaala when deducted from the half of the day or the half of the night gives the Nata Kaala as a remainder.

21-22 1/2 The Lagna which is found out through Poorvanata on Lankodaya by means of traversed degrees etc., through the Paschimanat on Lankodaya by means of the to be traversed degrees that is the 10th house. 6 signs added to the 10th House gives the 4th House.

23-24 The Ascendant is deducted from the 4th House and the 4th House is deducted from the 7th House, both the resultants. are divided by three separately. The first figure arrived at is multiplied by one and two and is added to the Ascendant. The Second figure arrived at is multiplied by one and two and is added to the 4th House. In this way there will be 6 Houses.
The half of the Summation of the former and the latter is called Bhava-Sandhi. In this way by adding 6 signs in the 6 Houses and 6 sandhis, all the other Houses and Sandhis will be known.
Practice
Verse 14 says that adding the ayanāṁśa to the Sun's position gives the Sāyana Sun. What is the ayanāṁśa actually measuring?
Write your answer down before opening the explanation.
Show the answer and why
Answer: The gap between the tropical zodiac, which is measured from the equinox, and the sidereal zodiac, which is measured against the fixed stars — a gap that grows slowly because the equinox itself drifts.
Two zodiacs, both real, measuring from different starting points. Jyotish uses the sidereal one; Western astrology uses the tropical one; the difference between them is currently around 24 degrees, which is most of a sign. That is why the same person is a Pisces in one system and an Aquarius in the other, and it is not a disagreement about the sky. It is two rulers with different zeroes.

Chapter 5 spends considerable effort on Svodaya — the rising times of the signs at your own latitude, converted from Laṅkodaya, the rising times at the equator. Why does latitude matter?
Write your answer down before opening the explanation.
Show the answer and why
Answer: Because the ecliptic meets the horizon at a different angle depending on how far north or south you are, so signs take different amounts of time to rise at different places.
At the equator every sign rises in roughly the same two hours. At high latitudes the difference is dramatic — some signs take four hours to rise, others forty minutes. This matters practically: it is why two people born at the same instant in Ulm and in Los Angeles have different ascendants, and it is why a chart cast without a place is not a chart. Planetary longitudes are the same everywhere on earth at a given instant. The ascendant is not.

The ascendant travels the full zodiac in about twenty-four hours. Roughly how long does it take to move one degree, and what does that imply about a birth time recorded only to the nearest hour?
Write your answer down before opening the explanation.
Show the answer and why
Answer: About four minutes per degree. A birth time good to the nearest hour puts the Lagna anywhere within a fifteen-degree band, which is half a sign.
Work through what that costs you. The rising sign itself is usually still secure — you would have to be unlucky, or born near a sign boundary, for a half-sign band to straddle two signs. But anything that depends on the Lagna degree is gone: the Bhāva cusps, several vargas, and any timing technique fine enough to care. This is not a reason to despair; it is a reason to know which of your conclusions are load-bearing on the minute and which are not.
Someone tells you they can identify the exact minute of a life event from a Prāṇadaśā, a sub-sub-sub-period lasting a few hours. What would have to be true for that claim to be meaningful?
Write your answer down before opening the explanation.
Show the answer and why
Answer: The birth time would have to be accurate to within a few seconds, and the chain of inference from the natal chart to that event would have to hold undiminished through five levels of subdivision.
Neither is usually true and the first almost never is. Hospital records round to the minute at best, and often to five. This is the single most useful thing Chapter 5 gives you, and you are meeting it in Week 2 so that it is already familiar when Week 10 hands you the tools to make exactly this mistake. Precision of arithmetic is not precision of prediction: you can compute a Prāṇadaśā to the second from a birth time that is wrong by ten minutes, and the computation will be immaculate and the answer meaningless.
Apply it to a chart
Chart C — Leonardo DiCaprio, the timing chart — Birth-certificate data and a well-dated public record — which is what makes timing work possible at all. · about 12 min
| Graha | Sign | House | Degree | Nakshatra | Condition |
|---|---|---|---|---|---|
| Sun | Libra | 2 | 25°09'44" | Vishakha 2 | debilitated |
| Moon | Virgo | 1 | 23°10'19" | Hasta 4 | neutral |
| Mars | Libra | 2 | 16°05'31" | Swati 3 | neutral |
| Mercury | Libra | 2 | 6°15'25" | Chitra 4 | neutral |

| Ketu | Taurus | 9 | 17°46'00" | Rohini 3 | not assigned in BPHS |
| Lagna | Virgo | 1 | 9°37'18" | Uttara Phalguni | lord Mercury |
Chart C is Leonardo DiCaprio, and it was chosen for the course precisely because of what this chapter is about: the birth time comes from a birth certificate and is recorded to the minute. Compare it with Chart B, Einstein, whose certificate records "eleven and a half" — a half-hour statement.
- Look up both charts' provenance in the chart library. Note the recorded time for each, and what the source of that time is.
- The ascendant moves roughly one degree every four minutes. For Einstein, recorded to the nearest half hour, what is the widest range of possible Lagna degrees? Does the rising sign change over that range?
- Write one sentence for each chart stating what you may conclude confidently from the Lagna, and what you should not.
- For your own chart: where did your birth time come from — a certificate, a hospital record, a family memory, or a rounded number? Write it down. It belongs at the top of every reading you ever do of your own chart.
Check your understanding
Answer from memory first. Looking back at the reading before you try turns a memory test into a copying exercise.
Which of a chart's elements changes with the place of birth, and which do not?
Write your answer down before opening the explanation.
Show the answer and why
Answer: The ascendant and the house cusps change with place. The planetary longitudes do not — they are the same for everyone on earth at that instant.
Worth being precise about, because it explains why birth place is asked for at all. Two people born the same second in different cities share every planetary position and share almost nothing about their houses.
A student asks where BPHS explains how a chart is actually computed. What do you tell them, and what do you warn them about?
Write your answer down before opening the explanation.
Show the answer and why
Answer: Chapter 5. And that it is a manual method built for an almanac and a shadow-stick, superseded in practice, worth reading once for what it reveals about the inputs rather than for the procedure.
Being able to say both halves of that is the mark of having read it properly. The chapter is not obsolete in what it teaches — it is obsolete in what it asks you to do.
This course uses the Lahiri ayanāṁśa. Does BPHS specify which ayanāṁśa to use?
Write your answer down before opening the explanation.
Show the answer and why
Answer: No. It tells you an ayanāṁśa must be applied; it does not settle which.
Several are in use and they differ by up to a degree or so, which is almost always irrelevant and occasionally decisive — precisely when a planet sits near a sign or nakshatra boundary. The course states its choice openly on every computed chart, along with the ephemeris and the node convention, so you always know what you are looking at. Getting into the habit of asking software the same question is worth doing.
What you carry forward
Two things grow across the whole course. This unit adds to both.
To your chart-analysis process
- **Step 2 (completed) — establish the chart.** Verify the birth data and where it came from. Note the ayanāṁśa. Note the birth-time uncertainty explicitly, because it constrains every step after this one.
To your field manual
- The ascendant moves about 1° every 4 minutes, a full sign in roughly 2 hours at middle latitudes.
- Planetary longitudes depend on time only. The ascendant and houses depend on time *and* place.
- Record where a birth time came from — certificate, hospital record, family memory, rounded figure — at the top of every reading.
- Precision of arithmetic is not precision of prediction. Every subdivision inherits the birth time's error.

- State roughly how fast the ascendant moves, and what that means for birth-time accuracy
- Describe what would have to be true for a Prāṇadaśā claim to be meaningful
