Notes

  • This function is case-sensitive. For example, using apr instead of Apr returns an error.

  • Using extra whitespace not included in the internal format strings returns an error.

  • Trailing characters after the date format has been satisfied are ignored. If you erroneously use a date string of 06/20/2006 with date format mm/dd/yy, the trailing 06 is ignored and the date is interpreted as June 20, 2020.

  • Long Format (Weekday, Mon dd, yyyy) is not verified for a day-of-week match to the given date.

    For example: For date string Sunday, March 13, 2007 with date format Long Format, the input date string is parsed correctly for March 13, 2007, although March 13, 2007 does not fall on Sunday.

  • If you specify a date that is earlier than 01-01-1970, this function returns an error.

  • The latest date supported by this function is 12-31-2037.

  • When the yy format is used, this function interprets years in the range 1970 to 2029.
