About This Tool
Recurring events: Birthdays and anniversaries repeat every year. The counter shows how long until the next occurrence and how many years it will be.
One-time events: Special events that only happen once. After they pass, they'll be marked as completed.
Leap year birthdays: If someone was born on February 29, their birthday will be celebrated on February 28 in non-leap years.
Approximate times: Weeks and months are approximations (7 days/week, ~30.4 days/month) for quick reference.
