Purnima in Boston: questions

+ How many Purnima days are there in 2033 in Boston?
12, computed for Boston's coordinates and the America/New York time zone. The first falls on Sat, Jan 15 and the last on Mon, Dec 5.
+ Are Boston Purnima 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 Boston. In 2033, 8 of 12 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 Purnima tithi is in force at sunrise. The exact full-moon instant is also shown, because many people observe the evening the moon is fullest. 1 of this year's 12 entries for Boston 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.
