Purnima in San José: questions
+ How many Purnima days are there in 2027 in San José?
12, computed for San José's coordinates and the America/Costa Rica time zone. The first falls on Fri, Jan 22 and the last on Mon, Dec 13.
+ Are San José 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 San José. In 2027, 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 San José 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.
