Excel 日期公式 + 3 个月

Question

I am looking to have a formula that takes the date that is manually input in a cell (E2) and automatically populates a date in the column next to it (F2) that is + 3 months from the date manually input in (E2).

eg. If (E2) has 03/11/2021 input manually then the formula in (F2) would populate 03/02/2021. image of part of the sheet

Answer 1

Is this what you are looking for?

=DATE(YEAR(A1),MONTH(A1)+X,DAY(A1))

where X = 3

Answer 2

One can use EDATE() :

=EDATE(A1,3)

The second criteria is the number of Months to add.

EDATE will go to the number of months then try to equate the day. If the day exceeds the number of days in the target month it returns the last day of the target month.

For example =EDATE(DATE(2021,11,30),3) will return the 28th of February 2021.
