What are the limits of Birthday & Anniversary Calendar?
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. Data stays in browser memory. No account connection, automatic storage, live holiday feed or background reminders. ICS exports must be imported into your own calendar app.
