This function accounts for leap years.

When passing a date/time object as a string, you must enclose it in quotation marks. Otherwise, it is interpreted as a numeric representation of a date/time object.

Note: You can pass the CreateDate function or Now function as the date parameter of this function; for example, #DayOfYear(CreateDate(2001, 3, 3))#
