Syntax

WEEKDAY(date, [type])

• date - The date for which to determine the day of the week. Must be a reference to a cell containing a date, a function returning a date type, or a number.
• type - [ OPTIONAL - 1 by default ] - A number indicating which numbering system to use to represent weekdays. By default counts starting with Sunday = 1.
  • If type is 1, days are counted from Sunday and the value of Sunday is 1, therefore the value of Saturday is 7.
    
  • If type is 2, days are counted from Monday and the value of Monday is 1, therefore the value of Sunday is 7.
  • If type is 3, days are counted from Monday and the value of Monday is 0, therefore the value of Sunday is 6.

Notes

• Ensure that the input to the function is either a reference to a cell containing a date, a function which returns a date object such as DATE, DATEVALUE or TO_DATE, or a date serial number of the type returned by the N function.
• WEEKDAY does not autoconvert number formats. Therefore, WEEKDAY(10/10/2000) is interpreted as WEEKDAY(0.0005), the quotient of 10 divided by 10 divided by 2000.
• WEEKDAY returns the day of week in numeric form, not as a letter (e.g. 'M' or 'F') an abbreviation (e.g. 'Tue' or 'Thu') nor as a full day name (e.g. 'Wednesday'). To get the name of the weekday, use the TEXT function or change the number formatting on the cell.
