Imlek Calendar

One date, five calendars — Gregorian, Chinese (Imlek) with Anno Konghucu & zodiac, Javanese (pasaran · weton · wuku), Hijri, and BaZi 八字. Dates come from an authoritative lunar library, so they are accurate.

Imlek dates, ganzhi, zodiac, solar terms, festivals and BaZi are computed by the lunar-javascript library (6tail). Hijri uses the Umm al-Qura calendar (may differ ±1 day from Indonesian sighting). Pawukon cycles (wuku/windu) use a standard calibration.
