Prepare the calendar
Create an annual celebration calendar with ages and leap-day handling.
Use the sample to inspect the exact workflow. Set the planning range and replace the demonstration entries with your own dates.
Check the assumptions
Optional year in the original date enables anniversary counts. February 29 can be skipped or observed on February 28 or March 1 in non-leap years. Dates are explicit occurrences, not automatic reminders.
Dates are inclusive in planning inputs unless labeled exclusive. Timed events require a valid IANA timezone; ambiguous daylight-saving times are rejected.
Keep and share the result
Review warnings and totals, then export the supported ICS, CSV, JSON or report formats. Exports contain the chosen data, so review sensitive names and notes before sharing.
No calendar account is connected and no reminder is scheduled by this website. Import the ICS file explicitly into a calendar app; save a JSON draft if you want to continue editing later.
