About Lunar Calendar
I built this for my mom and dad’s birthdays. They keep their birthdays on the lunar calendar, so the solar date changes every year, and Google Calendar has no events that repeat by lunar date. So I made a calendar where you enter a day once and it adds the coming years to your calendar.

- There is no server. The names and dates you enter stay in this browser.
- From Google, it asks only for permission to manage the one calendar it creates, “Lunar days”. It does not ask to see your name, email address, contacts or other events.
- Only visits are counted. No cookies are used, and nothing you enter is sent.
