Amavasya in Buenos Aires: questions
+ How many Amavasya days are there in 2033 in Buenos Aires?
13, computed for Buenos Aires's coordinates and the America/Argentina/Buenos Aires time zone. The first falls on Sat, Jan 1 and the last on Wed, Dec 21.
+ Are Buenos Aires 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 Buenos Aires. In 2033, 9 of 13 dates match the Indian (Ujjain) date, 4 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. 1 of this year's 13 entries for Buenos Aires are flagged because of that. 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.
