Author: Xiaoyang Last Modified: 2019-06-19

In Excel workbook, the DATE function can help us to combine year, month and day numbers from separate cells to a valid date.

The syntax for the DATE function in Excel is:

=DATE( year, month, day )


year – A number is between 1 and 4-digits number that indicates the year number.

  • If year is between 0 and 1900, Excel will add 1900 to the year automatically.
  • If year is between 1900 and 9999, the value will be used as the year value.

month - A number indicates the month value. (From 1 to 12 normally)

  • If month is greater than 12, Excel will add the number of months to the first month of the specified year. For example, DATE(2018,14,2) will return the date 2/2/2019.
  • If month is less than 1, Excel will subtract the absolute value of month plus 1 from the first month of the specified year. For example, DATE(2018,-4,15) will return the date 8/15/2017.

day - A number indicates the day value. (From 1 to 31 normally)

  • If day is greater than the number of days in the specified month, Excel will add that number of days to the first day of the month. For example, DATE(2018,1,35) will return the date 2/4/2018.
  • If day is less than 1, Excel will subtract the absolute value of day plus 1 from the first day of the month specified. For example, DATE(2018,9,-10) will return the date 8/21/2018.


Return a valid date based on the year, month and day columns.
