Return the weekday name (Monday…) or number for a date.
Copy this formula
=TEXT(A2, "dddd")TEXT with "dddd" gives the full weekday name and "ddd" the short name. For a number, WEEKDAY returns 1–7 (Sunday = 1 by default), which is handy for flagging weekends.
=TEXT("2026-06-23", "dddd")→TuesdayReturns the weekday name.
Flag weekends
=IF(WEEKDAY(A2, 2)>5, "Weekend", "Weekday")Code 2 makes Mon=1…Sun=7.
Use =WEEKDAY(A2) for 1–7, with an optional second argument to choose the week start.
