How to subtract 30 years from a date in Excel or Google Sheets?

To add or subtract years to a date you can use two formulas, but each has its nuances related to handling end of month day in leap years. The first one is suggested by official Microsoft Excel documentation:

=DATE(YEAR(TODAY()) + 30, MONTH(TODAY()), DAY(TODAY()))

For example if you try to add 1 year to February 29 2024 (which is a leap year), the result would be 01/03/2025. The DATE function in Excel constructs a date value based on the year, month, and day parameters you provide. When the provided day exceeds the number of days in the resulting month, Excel rolls over to the next month. This mechanism is intended to avoid invalid dates and ensures that every date calculation results in a valid and logical date value.

Another formula will handle month endings more gracefully, especially in case of leap year:

=EDATE(TODAY(), -(30 * 12))

For example if you try to add 1 year to February 29 2024 (which is a leap year), the result would be 28/02/2025. This happens because EDATE seamlessly handles the end-of-month logic. If the resulting month has fewer days than the start date's day, EDATE returns the last day of the resulting month. Thus, when moving from a leap year to a non-leap year, adding a year to February 29 results in February 28 of the following year, as this is the last valid day of February in a non-leap year.

Replace TODAY() with a cell reference (for example: A1) to manipulate dates other than today's date.
