DateAny valid date (1/1/000112/31/4000), expression that returns a date, or field that contains a date. The parameter can also be the numeric representation of a date (11460970).

Description:
Returns a number representing the day of year (1366) for any valid date (1/1/000112/31/4000).
You can use the DayOfYear function to check whether a particular year is a leap year. Given a field Year, the formula DayOfYear ( Date ( 12; 31; Year )) would return 366 if Year was a leap year, and 365 if it wasn't.
Note that the year is optional. DayOfYear ("12/1") will return the appropriate integer for December 1st in the current year.
