Calculate Week commencing
Hi All Can anyone help me with a formula to calculate the Week Commencing date based on a date supplied? I found this: http://www.bygsoftware.com/Excel/fun.../iso_dates.htm and tried: =1+INT((A1-DATE(YEAR(A1+4-WEEKDAY(A1,2)),1,5)+WEEKDAY(DATE(YEAR(A1+4-WEEKDAY(A1,2)),1,4),2))/7) Using a date in A1 of "28-Sept-05" (formatted) but this returns a completely wrong date "08/02/1900" Am I doing something wrong? Excel Version 2000 Any help appreciated.
