Hello Cire,

Thank you for your feedback! You’re correct—simply adding years by multiplying 365 days doesn’t account for leap years, which can make the result inaccurate over longer periods.

To accurately add years to a date (including leap years), you should use the EDATE or DATE function in Excel:

Use EDATE:
If your date is in cell A2 and you want to add 4 years:
=EDATE(A2, 12*4)
This will add exactly 4 years, taking leap years into account.

Use DATE:
If your date is in cell A2 and you want to add 4 years:
=DATE(YEAR(A2)+4, MONTH(A2), DAY(A2))
This also accurately adds years, even if there are leap years.

These methods are more reliable for date calculations over several years.
