What is DAY function in Excel?

DAY function is one of Date and Time functions in Microsoft Excel that returns the day of a date, represented by a serial number. The day is given as an integer ranging from 1 to 31.

Syntax of DAY function

DAY(serial_number)

The DAY function syntax has the following arguments:

  • Serial_number: The date of the day you are trying to find. Dates should be entered by using the DATE function, or as results of other formulas or functions. For example, use DATE(2008,5,23) for the 23rd day of May, 2008.

Note:

Problems can occur if dates are entered as text.

DAY formula explanation

Microsoft Excel stores dates as sequential serial numbers so they can be used in calculations. By default, January 1, 1900 is serial number 1, and January 1, 2008 is serial number 39448 because it is 39,448 days after January 1, 1900.

Values returned by the YEAR, MONTH and DAY functions will be Gregorian values regardless of the display format for the supplied date value. For example, if the display format of the supplied date is Hijri, the returned values for the YEAR, MONTH and DAY functions will be values associated with the equivalent Gregorian date.
