How to use Recurring Calendar Date Generator
Advance by a fixed count of Gregorian calendar periods from the original date. Monthly/yearly dates retain the original day and skip invalid dates, following RFC 5545’s invalid-date principle.
- Enter first date, interval in selected periods, occurrences to return.
- Check the model, units, and supported limits before calculating.
- Run the tool, inspect the result, then copy or download it.
Good to know
- A limited recurrence subset, not a full RRULE parser. 1–1000 occurrences, interval 1–1000, at most ten calendar years after start, years 0001–9999. Date-only UTC arithmetic; no time zones or holidays.
- Runs locally. Numeric inputs are bounded; floating-point output is approximate and rounded to 12 significant digits. Unsupported or non-finite calculations produce an error.
