Add or subtract months to date in Excel

For adding or subtracting months to dates, it’s not fit to add or subtract 30 from the dates because months contain different number of days in a year, some contain 30 days, some contain 31 days, while some contain 28 or 29 days. Therefore, we need to apply the EDATE function to deal with this situation.

= EDATE(date, number of months)

1. Select the blank cell you will place the calculating result, type the formula =EDATE(A2,3), and drag this formula cell’s AutoFill handle to apply this formula to other cells as you need.
Note: To subtracting 3 months from the date, please use this formula =EDATE(A2,-3).

2. As you see, the EDATE function will return 5-digit numbers. Please keep these 5-digit numbers selected, and click Home > Number Format box > Short Date to convert them to dates back. See screenshot:

Now you will see it has added or subtracted the same number of months to the dates in bulk. See screenshot:

Add or subtract years to date in Excel

For example, you will add 6 years to a batch of dates in Excel, you can do as follows:

= DATE(YEAR(date) + number of years, MONTH(date),DAY(date))

1. Select the blank cell you will place the calculating result, type the formula =DATE(YEAR(A2)+6,MONTH(A2),DAY(A2)), and press the Enter key.
Note: To subtract 6 years from the date, please apply this formula =DATE(YEAR(A2)-6,MONTH(A2),DAY(A2)).

2. If needed, drag the formula cell’s AutoFill handle to apply this formula to other cells as you need.

Add or subtract a combination of years, month, and days to date in Excel

In some cases, you may need to add or subtract years, months, and days at the same time, says add 3 years 5 months and 15 days. In this case, you can apply the DATE function to solve the problem.

= DATE(YEAR(date) + number of years, MONTH(date) + number of months, DAY(date) + number of days)

1. Select the blank cell you will place the calculating result, type the formula =DATE(YEAR(A2)+3,MONTH(A2)+5,DAY(A2)+15), and press the Enter key. See screenshot:
Note: To subtract the combination of years, months, and days together, please use this formula =DATE(YEAR(A2)-3,MONTH(A2)-5,DAY(A2)-15).

2. If needed, please drag this formula cell’s AutoFill handle to apply this formula to other cells.
