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.
