Masik Shivaratri in Boise: questions

+ How many Masik Shivaratri days are there in 2026 in Boise?
12, computed for Boise's coordinates and the America/Boise time zone. The first falls on Fri, Jan 16 and the last on Sun, Dec 6.
+ Are Boise Masik Shivaratri dates the same as in India?
Not always. A tithi starts at the same instant everywhere, but the local midnight that decides the day happens at a different moment in Boise. In 2026, 6 of 12 dates match the Indian (Ujjain) date, 6 fall a day earlier and 0 a day later.
+ How is the date decided?
This calendar uses the local day whose following midnight (computed as the midpoint between sunset and the next sunrise) falls inside the Krishna Chaturdashi tithi. 1 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.
