Never miss an important lunar date
Lunar lets you record any important lunar date (month + day) — festivals like Mid-Autumn (Month 8, Day 15), Dragon Boat or family anniversaries — and it figures out the correct solar-calendar date every year. Each lunar-year date becomes its own Google Calendar event at the exact converted date with 09:00 reminders 1 week & 1 day before, so the celebration never drifts.
Built with chinese-lunar
(MIT) — the lunar data covers 1900–2100 from the Purple Mountain Observatory / Hong Kong Observatory — plus a custom
lunar2solar conversion on the same DATD table.
Leap months and short 29-day months are handled automatically.
