- If you create a lunar anniversary, a schedule corresponding to that lunar date is created every year.

- Because a separate calendar for the lunar anniversary app is created in Google Calendar to manage lunar anniversaries, the user's existing schedule is not affected by the lunar anniversary app and is not visible in the lunar anniversary app.

- Supports leap month and eve function.

- Using the yin-yang calendar information provided by the Korea Astronomy and Space Science Institute, it is possible to create an anniversary schedule up to 2050-12-31 according to the solar calendar.

- When the lunar anniversary app is launched for the first time, you must allow access to the user's calendar.

- The Lunar Anniversary app is not a lunar calendar, but an app for managing lunar "anniversaries", so it does not support the lunar calendar views, seasons, and days without hands provided by a general lunar calendar app.
