Tap any Tibetan term or kanji to see its English. Tap an almanac line to read what it means, what it favours and what to avoid, with the published source it comes from. Computed on the phone Everything is calculated on the device for any date from 1900 to 2100: Tibetan dates with Svante Janson's published arithmetic, new moons and solar terms with Jean Meeus's algorithms and the VSOP87 solar theory. The results are checked against Edward Henning's Tibetan calendars and the National Astronomical Observatory of Japan. Private The app has no internet permission. Your location is taken once from GPS when you ask for it, picked from an offline list of cities, or typed in as coordinates, and it stays on the phone. Give me a tip

What’s new (1.0.1)

The old Japanese calendar now names its almanac bands as the sources do: the middle band (中段) holds the twelve stations alone, the lunar lodge has its own line, and the lower band (暦注下段) and the selected days (選日) are listed separately. The day's 九星 moves next to the month and year stars.
