A living almanac built on the real lunisolar calendar. Every date shows its day pillar and one of the twelve Day Officers — the traditional way to find lucky days for weddings, moves, openings and signings.
Tap a date to see its day pillar, Day Officer and task picks.
The twelve Day Officers (建除十二神) rotate one step per day through the lunar month: Establish, Remove, Full, Level, Settle, Hold, Break, Peril, Complete, Harvest, Open, Close. Their cycle restarts at each solar term, which is why the same calendar date can carry a different officer year to year. We compute every day pillar from the astronomical lunisolar calendar — the same engine behind our free saju calculator — then map each officer onto everyday tasks like weddings, moving and contract signing.
