Add a number of years to a date and get the resulting date and weekday. Useful for anniversaries, long-term contracts, and maturity dates. A February 29 start is clamped to February 28 in years that are not leap years.
How this is calculated
Years are added on the calendar, keeping the same month and day where possible. A February 29 date lands on February 28 in a non-leap target year, since that year has no February 29.
How to use
- Enter the start date in YYYY-MM-DD format.
- Enter the number of years to add.
- Read the resulting date and its weekday.
Examples
- Leap day clamp:
2024-02-29 + 1 year = 2025-02-28 - Five years:

2026-03-15 + 1 year = 2027-03-15
