Chapter 12 Dictionary of Functions 289
WEEKDAY
The WEEKDAY function converts a date to a number that represents the day of the
week using one of three numbering schemes.
WEEKDAY(date-time, [number-scheme])
 date-time: A date in any of the accepted date formats or a reference to a cell
containing such a date.
 number-scheme: Optional; a single digit that specifies how days are numbered:
1 or omitted counts Sunday = day 1, Saturday = day 7.
2 counts Monday = 1 through Sunday = 7.
3 counts Monday = 0 through Sunday = 6.
YEAR
The YEAR function extracts the year number from a date.
YEAR(date-time)
 date-time: A date or a reference to a cell containing a date.
Examples
WEEKDAY("Apr 6, 1988", 1) returns 4 (Wednesday, the fourth day if you start counting Sunday as day
1).
WEEKDAY("Apr 6, 1988") returns the same value as the preceding example (numbering scheme 1 is
used if no number-scheme argument is specified).
WEEKDAY("Apr 6, 1988”, 2) returns 3 (Wednesday, the third day if you start counting Monday as day 1).
WEEKDAY("Apr 6, 1988”, 3) returns 2 (Wednesday, day number 2 if you start counting Monday as day
0).
Examples
YEAR("April 6, 1988") returns 1988.
YEAR(NOW()) returns 2006 when evaluated on June 4, 2006.
