📅 Syncs to Apple Calendar

Events land in your native iOS Calendar — with reminders, in the app you already use every day. No separate app to check.

🔄 Auto Gregorian conversion

Lunar dates shift every year. The app converts them to the correct Gregorian date for the next several years automatically.

🙏 Buddhist & Taoist fasting

Pre-built monthly fasting schedules for observant practitioners. Pick a template and all dates are added in one tap.

🎊 Traditional festivals

Spring Festival, Qingming, Dragon Boat, Mid-Autumn, Double Ninth, and more — all pre-configured and ready to add.

🎂 Lunar birthdays

Add a birthday once by lunar date. The app calculates the right Gregorian date each year so reminders always fire on time.

✏️ Custom events

Not in the templates? Add any date from the Chinese calendar as a one-off or repeating event with a custom name and notes.

Built-in calendar templates
