Returns the day of the week corresponding to a date. The day is given as an integer, ranging from 1 (Sunday) to 7 (Saturday), by default.
Syntax
WEEKDAY(serial_number,return_type)
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. Problems might occur if dates are entered as text.
Argument | Description | Remarks |
|---|---|---|
serial_number | The date that falls within the year you want to find. |
|
return_type | A number that determines on which day the week begins. The default is 1. |

General remarks
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.
Example
To make the following example easier to understand, you can copy the data to a blank sheet and then enter the function underneath the data. Do not select the row or column headings (1, 2, 3... A, B, C...) when you copy the sample data to a blank sheet.
 | Note 2/14/2008 is a Thursday. |
