Purnima in Boise: questions

+ How many Purnima days are there in 2028 in Boise?
13, computed for Boise's coordinates and the America/Boise time zone. The first falls on Tue, Jan 11 and the last on Sun, Dec 31.
+ Are Boise 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 Boise. In 2028, 8 of 13 dates match the Indian (Ujjain) date, 5 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 13 entries for Boise 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.
