Deepavali in the US

[Guest guest]

I have difficulty in following the logic of Dileepan in instructing that

Deepavali should be celebrated on Sunday, Nov.3 while it is on Monday, Nov.4 in

India. He is suggesting that Chaturdasi (and Amavasai )comes first to US before

it dawns in India. He seems to be blindly converting Indian Standard time to

corresponding American EST to argue his suggestion. This approach appears to be

astronomically incorrect as Thithi and Lagnam are based on tine of Sunrise and

Sunset (Moonset and Moonrise) locallly determined by lattitude and longitude on

earth with respect to moving Zodiac in Hindu Thirukanitha Panchangam. Amavasai

cannot come first to US before it does in India if we all agree Sun rises in the

East and sets in the west and that an astronomical Thithi would precede in India

before US. We do not follow 12.01 AM as beginning of day and 12 PM as end of

the day in Hindu Panchangam. Suryodayam and Suryaasthanam on the English Clock

constitutes a day which can be more than 24hr or less depending on the season

ina place determined by lattitude and longotude. Remember you can see midnight

(English time) Sun in Sweden during summwer and very little Sun in the winter.

Calculation of duration of Thithi, lagnam, Rahu kalam, Kuligai and Yamakandam

are all based on duration of Sunlight division at a given place in every day

of week. It is a nightmare to apply Hindu panchangam in Sweden during summer

and winter. Even in the US east coast, do not blindly follow Rahukalam on

Sunday as 4.30-6pm during winter as Sun set happens by 4pm. People observing

Sandhyavandanam strictly should be aware of early morning sunrise time and

evening sun set time at their place to conform to Sastram.

 

I am raising this issue as an academic point of astronomic evaluation and not to

question the religious pursuit of individuals as advised by their Acharyas.

Hindu system of astronomical calculation based on fixed Stellar constellation

and ayanamsam of earth(varying angle of axis of rotation overtime within

restricted angle of axis) on a rotating Zodiac is complex that only real experts

can accurately depict the phases of moon per say for any place on earth. This

is a scientific exercise and not a matter of religious belief.

This matter was discussed at length in a different list

about 18 months ago in the context of Yajur Upakarma.

Let me give a brief explanation here.

 

The start of thithi is based on the position of moon

with respect to earth. Therefore, the instant in time

that marks the birth of a thithi is the same all over

earth. Whether U.S. or Japan, or Norway, it begins at

the exact same instant.

 

So, when amavasyai begins on Nov 4th at 6:00 a.m. in

India, it begins at that same instant everywhere else

also. That instant in time is 7:30 p.m. the previous

calendar day in the U.S. because U.S. is 10.5 hours

behind India. That instant in time will be 8:00 a.m.

in Singapore which is 2 hours ahead.

 

After having determined when a thithi begins and ends

we need to apply the rules for determining a given

function. The rule for Deepavali is that at the time

of snanam, which is between 3 and 4 a.m., Chaturdasi

must be present.

 

It is true that there are difficulties in places

where the sun never sets, or never rises at some

times of the year. This does not mean these rules

do not apply in other places where such extreme

conditions are not there. Otherwise, even the

determination given for India can be questioned.

The sun never rises in Norway, so how come Deepavali

is on Nov 4th in India?

 

In any case, I have not just made any of this up.

These are based on careful study and consultation

with experts who have been in the business of making

such determinaton for years. Thus I stand by the

determination I have provided. If you wish you take

it, take it. Or else, just leave it. It won't please

me if you do, and it will not offend me if you don't.

Jai Sriman Narayana!

 

With best regards to Sri Dileepan, I would like to

express a difference of opinion.

 

According to Indian calandar, it is my understanding

that, Hindu day starts from the sun rise.

Consequently, thithi is observed in terms of ghadias

and vighadias etc FROM the LOCAL SUN RISE. Even within

India, the Panchangam advises to give correction for

sun rise time (eg. from Vishakapatnam to Hyderabad).

The rahu kalam, durmurtham, etc. are usually

calculated from sun rise. Therefore, Deepavali falls

on Monday and not on Sunbday. Similarly, for Ekadasi,

we have to observe Ekadasi on the day when ekadasi

thithi exists at the local sun rise. I have very

little knowledge in astronomy/panchangam, and I

request scholars to comment on this often

misunderstood topic.

 

With all glories to Lord Sri Venkateswara, I remain,

 

Sincerely

Narender Reddy
