ExampleFormulaResult

Syntax and Arguments:

The Syntax for the WEEKDAY Formula is:

Function Arguments ( Inputs ):

serial_number – The date in Excel serial number format or entered as a date with quotations (“s) surround the date. Example: You can not enter 11/12/2015 directly into the cell. Instead you need to enter “11/12/2015” or you would need to use the corresponding serial number: 42320. Alternatively, you can reference a cell with the date 11/12/2015 entered. Excel automatically converts dates stored in cells into serial format (unless the date is entered as text).

return_type – OPTIONAL. A number indicating which day of the week is considered the first day of the week. 1 (Default) for Sunday, 2 for Monday, etc.

Additional Notes

Simply enter a date. By default, the first day of the week is considered Sunday. Enter 2 to change the start date to Monday, 3 for Tuesday, etc..

WEEKDAY Examples in VBA

You can also use the WEEKDAY function in VBA. Type:
application.worksheetfunction.weekday(serial_number,return_type)
For the function arguments (serial_number, etc.), you can either enter them directly into the function, or define variables to use instead.
