Chinese lunar birthday reminder for your family
Many parents and grandparents celebrate their birthday on the Chinese lunar calendar, not the Gregorian one. So every year the "real" birthday lands on a different date on your phone — and it is genuinely easy to miss, especially if you live far from family.
MoonCal gives you a reminder in the calendar app you already use — Apple Calendar, Google Calendar, Outlook, or Fastmail — so you never have to do the lunar-to-Gregorian math again. You set it up once, and it keeps working year after year.
Why lunar birthdays are so easy to forget
How MoonCal keeps the date right every year
You enter the birthday once as a lunar date. MoonCal converts it into the correct Gregorian date for the next 20 years and publishes the result as a calendar subscription. Your calendar app fetches that subscription and shows the birthday on the right day each year — automatically, with no maintenance from you.
Set a reminder before the day
You can choose reminders 1 day or 3 days before each birthday. Reminders start off, and delivery depends on your calendar app and its notification settings.
Share it with the whole family
Because MoonCal produces a standard subscription URL, you can send the same link to siblings or relatives. Everyone adds it to their own calendar app and sees the same dates; reminder support depends on each app — so remembering Grandma's birthday is no longer one person's job.
Works with the app you already have
You do not need a new app or another login on your phone. MoonCal works through the calendar you already check every day:
