Amavasya in Boise: questions

+ How many Amavasya days are there in 2026 in Boise?
12, computed for Boise's coordinates and the America/Boise time zone. The first falls on Sun, Jan 18 and the last on Tue, Dec 8.
+ Are Boise 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 Boise. In 2026, 5 of 12 dates match the Indian (Ujjain) date, 7 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. 2 of this year's 12 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.
