Nakshatra/Tithi question

March 2, 2003

Dear Gurus, learned ones, and the seekers of divinity,

I have a question regarding tithi start/end time and

nakshatra start/end time for daily purposes..

Following are some instances:

1) Let's say the 4th tithi (Chaturthi), technically

starts at 11:00 am Sunday. Does whole Sunday get

considered as Chaturthi? If so, from what time till

what time? sunrise to sunset? Or, does Chaturthi

exactly start at 11:00 am and lasts for exactly 12

degrees ? Can somebody please fill me in on this ?

I've heard there are various schools of thoughts:

e.g 1) that considers sunrise time as beginning till

next day's sunrise (astrological day in fact)

2)another one that considers: if technically,

Chaturthi starts before 12:00 pm, the whole day is

Chaturthi;

&

3) that considers the technical beginning time and the

time when 12 degrees pass.

4) How is Nakshatra start/end time interpreted ? I

guess, my question regarding the tithi holds the same

for Nakshatra too..

I hope my concern can be understood.

I've been dwelling into this field for about a year,

and you know how it goes..so many things fundamentals

go bypassed....thank you for your time, and i will

really appreciate anybody's input on it...

Dear Shailesh,

You are not the only one who has been stumped with this problem.

Technically ( or rather, mathematically ), the Tithi changes every time the

longitudinal difference between the Sun and the Moon attains a multiple of

12 degrees. Thus if this difference was 36 degrees at 11:00 am, then the 3rd

Tithi would be ending and the 4th Tithi starting at that moment. Now, the

4th tithi would remain in force until the longitudinal difference becomes 48

degrees, irrespective of what the time of day ( or night ) it is !

However, it is very inconvenient for us to keeping changing our tithis at

irregular times, in accordance to the angular difference of the two

luminaries, so for social purposes, the tithi running at the time of sunrise

is accepted as valid for approximately 24 hours, i.e. till the next sunrise.

In other words, let's say the longitudinal difference between the sun and

the moon is 35 degrees, 59 minutes, and 59 seconds at the time of sunrise

( i.e 3rd Tithi ). The entire day ( upto the next sunrise ) will be

considered as the 3rd Tithi, in spite of the fact that technically the Tithi

would have been 4th ( i.e. at 36 degrees difference ), a few moments AFTER

sunrise.

Hope this helps.

TITHI COMPUTATION:

Tithi is a luni-solar day. It is among one of the Panchanga (five limb) of time

measurement, related with "Pataal Tattwa" i.e. Water element and generally

considered in Mahurata. It has not any connection with sunrise or sunset. Tithi

can be obtained by taking the difference between Moon's longitude and Sun's

longitude. Thus its begining and ending time does not depend on length of

weekday, sunrise, 12:00 am or 12:00 pm etc. There are total 30 lunar days, wich

are divided into two category, i.e. Shukla Paksha and Krishna Paksha. So there

are ultimately 15 tithis on each phase, 15 in Shukla(bright lunar phase) and 15

in Krishna(dark lunar phase). e.g. Shashthi (6th tithi) comence in Shukla paksha

as well as in Krishna paksha. Only the name of 15th tithi is different for two

mentioned phases. In Shukla paksha 15th tithi is called Poornamasi and in

Krishna paksha it is called Amavasya.

Example: Suppose on a certain day at mid-night Sun is into Aries at 10:00:00 and

Moon is into Taurus at 15:00:00 (its mean 45:00:00 i.e. 30 degrees of Aries and

15 degrees of Taurus has been travelled). Now take the difference between them.

(45:00:00 - 10:00:00) = 35:00:00 ;divide it by 12 we get. 2:55:00 or 2.916666 ,

in other words 2nd Tithi is elapsed and 3rd Tithi is currently running. And the

balance/remaining portion is 8.3333%. Now suppose on next mid-night Sun is at

11:00:00 Aries and the Moon 27:30:00 Taurus. Now we get the difference of

current position, wont fix Sun's or Moon's longitude. Hence (57:30:00 -

11:00:00) = 46:30:00 ;divide it by 12 as we did above, we get 3:52:30 or 3.875,

this gives 4th tithi (Shukla Paksha Chaturthi) is going on, whose 87.5% is

elapsed and 12.5% is remaining.

But when was any tithi started and when will it end?

Remember first tithi begins at the movement whenever Moon and Sun conjoin and

ends when this difference reached to 12 degrees which is the initial point of

second tithi, and third tithi starts when Moon reaches 24 degrees ahead of Sun.

Similarly when the difference between Moon and Sun becomes 180, this is the end

of 15th tithi(Poornamasi) and initial of 16th tithi (i.e. Krishana Paksha

Pratipat).

Example: Yesterday March 3, 2003. The Moon conjoined Sun at 7:34:15 am in

Karachi (5 hours ahead of GMT), at 18:12:00 Aquarius. This time (7:34:15 am)

was the starting time of 1st Tithi (Shukla Paksha Pratipat), Now observe(which

obviously can't without computer) when will this differece reach upto 12

degrees. The required 12 degrees difference between Moon and Sun happens at

March 4, 2003 at 8:39:00 am Karachi, which will be the ending time of 1st Tithi

and begining of 2nd Tithi. So 1st Tithi started March 3rd at 7:34:15 am and ends

March 4th at 8:39:00 am. We looked, there is not any connection of sunrise or

sunset or starting time of day with Tithi begining and terminating time.

NAKSHATRA COMPUTATION:

Nakshatra is another important aspect of time enumeration related with "Vayu

Tattwa" i.e. Air element. This is purely depends on the movment of Moon on

special points of zodiacal belt. The entire zodiac of 360 degrees is divided

into 27 equal segments. Each segment of 13 degree and 20 minute is called a

nakshtra or Lunar Asterism. First Nakshatra (called Ashvini) starts when the

Moon enters at 00:00:00 Aries and ends when the Moon reaches 13:20:00 Aries.

Second Nakshatra (called Bharani) starts at 13:20:00 Aries and ends at 26:40:00

Aries. Third Nakshatra (called Krithika) initiates at 26:40:00 Aries and

terminates when the Moon comes at 10:00:00 Taurus, and so on upto last nakshtra

(called Revati) which begins when Moon comes at 16:40:00 Pisces and terminates

at 30:00:00 Pisces.

Hence, the Moon can be at 13:20:00 Aries at any time, either morning, evening,

sunset or sunrise or even at the time of conjunction between Sun and Moon. And

technically there is not any inter-correlation among Tithi, Nakshatra and Day.

All are independant parameter of measuring time for astrological and

astronomical purpose.

No doubt, when certain Tithi coincide with specific Days and Nakshatras; special

Yogas are formed generally used in Mahuratam, called Siddha yoga and Amirta

Siddha yoga.

Hope above explaination will remove the doubts you have.

Regards

Imran.

Dear Imran,

Thank you for the explanation. I do understand that

part, however was more concerned about the practice of

some people, as I had mentioned in my question (below)

that I've bumped into couple of schools of thoughts,

which follow tithis/nakshatras from sunrise to sunset

according to whatever tithi/naks appears to be at

sunrise or at midday on that particular day..please

let me know if you know more on this, or if you have

come across the same ideas before.

Thanks again for your explanation.

Hari Om,

Dear Deepak,

Thanks for your input. I guess the technical

(mathematical) interpretation holds the supreme place.

For social/practical purposes, one can twig it around

a bit...

sounds good.

Many people observe what is known as "UDATYA TITHI ", i.e. the tithith at Local

Sun rise to be the Tithi for the whole day. Many others, take the TITHI to

start and end from the correct calculations. TITHI is diff in Longitude of

MOON - SUN divided by 12. So when this difference of Longitude is an exactly

divisible by 12, a Tithi starts. The ending is when the Next Tithi starts.

Due to the uneven movement of the MOON, a Tithi may start and End on the same

day. So the correct thing is find the Tithi for the required time of the event.

The same rules apply to Nakshatra's also. For Nakshtra there is no usage of the

Nakstra at sun-rise, as the Naakstra for the Whole day.
