Programming Tips and Gotchas

  • month must be an integer; it cannot be a date. Use DatePart("m", dateval ) to obtain a month number from a date.

  • If month has a fractional portion, it is rounded before calling the MonthName function.

  • MonthName with abbreviate set to False is the equivalent of Format(dateval, "mmmm").

  • MonthName with abbreviate set to True is the equivalent of Format(dateval, "mmm").
