Purnima in Tokyo: questions
+ How many Purnima days are there in 2027 in Tokyo?
12, computed for Tokyo's coordinates and the Asia/Tokyo time zone. The first falls on Fri, Jan 22 and the last on Mon, Dec 13.
+ Are Tokyo 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 Tokyo. In 2027, 8 of 12 dates match the Indian (Ujjain) date, 0 fall a day earlier and 4 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. No entry this year needed a flag. 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.
