Masik Shivaratri in Tucson: questions

+ How many Masik Shivaratri days are there in 2030 in Tucson?
13, computed for Tucson's coordinates and the America/Phoenix time zone. The first falls on Wed, Jan 2 and the last on Sun, Dec 22.
+ Are Tucson 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 Tucson. In 2030, 7 of 13 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 13 entries for Tucson 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.
