Amavasya in Bangkok: questions
+ How many Amavasya days are there in 2031 in Bangkok?
12, computed for Bangkok's coordinates and the Asia/Bangkok time zone. The first falls on Thu, Jan 23 and the last on Sun, Dec 14.
+ Are Bangkok Amavasya dates the same as in India?
Not always. A tithi starts at the same instant everywhere, but the sunrise that decides the day happens at a different moment in Bangkok. In 2031, 12 of 12 dates match the Indian (Ujjain) date, 0 fall a day earlier and 0 a day later.
+ How is the date decided?
This calendar uses the local day on which the Amavasya tithi is in force at sunrise. The exact new-moon instant is shown alongside. No entry this year needed a flag. Local temples may follow a particular sampradaya's rule, so check with them for ritual purposes.
+ How accurate are these times?
Times come from truncated astronomical series and should fall within a few minutes of a full ephemeris. Near a boundary a published panchanga may assign a different day. They are for planning practice, not for precise ritual muhurta.
