/text/scalc/01/func_weekday.xhp WEEKDAY function WEEKDAY Returns the day of the week for the given date value. The day is returned as an integer between 1 (Sunday) and 7 (Saturday) if no type or type=1 is specified. If type=2, numbering begins at Monday=1; and if type=3 numbering begins at Monday=0. Syntax WEEKDAY(Number; Type) Number, as a date value, is a decimal for which the weekday is to be returned. Type determines the type of calculation. For Type=1, the weekdays are counted starting from Sunday (this is the default even when the Type parameter is missing). For Type=2, the weekdays are counted starting from Monday=1. For Type=3, the weekdays are counted starting from Monday=0. These values apply only to the standard date format that you select under %PRODUCTNAME - PreferencesTools - Options - %PRODUCTNAME Calc - Calculate. Examples =WEEKDAY("2000-06-14") returns 4 (the Type parameter is missing, therefore the standard count is used. The standard count starts with Sunday as day number 1. June 14, 2000 was a Wednesday and therefore day number 4). =WEEKDAY("1996-07-24";2) returns 3 (the Type parameter is 2, therefore Monday is day number 1. July 24, 1996 was a Wednesday and therefore day number 3). =WEEKDAY("1996-07-24";1) returns 4 (the Type parameter is 1, therefore Sunday is day number 1. July 24, 1996 was a Wednesday and therefore day number 4). =WEEKDAY(NOW()) returns the number of the current day. To obtain a function indicating whether a day in A1 is a business day, use the IF and WEEKDAY functions as follows:
IF(WEEKDAY(A1;2)<6;"Business day";"Weekend")
