=MONTHDAY

The =MONTHDAY() function allows you to extract the numerical day of the provided date. Optionally allows you to add or subtract days from the extracted value.

=MONTHDAY(DateValue; OptionalAddOrSubtractDay)
  • DateValue – The date or date field token from which to extract the day.

  • OptionalAddOrSubtractDay (optional) – A number to add to or subtract from the day value.

    • Use a positive number to add days.

    • Use a negative number to subtract days.

  • Evaluates the provided date value.

  • Extracts the day portion of the date.

  • Applies the optional add or subtract value if provided.

  • Returns the resulting numeric day.

  • Formula functions are case sensitive and must be written in ALL CAPS.

  • The date must be in a valid format recognized by the system.

  • Field tokens containing dates can be used instead of hard-coded values.

  • Adding or subtracting days does not adjust the month automatically - this function only returns a numeric day value.

  • Useful for reminders, offsets, or simple date-based logic within workflows.

=MONTHDAY(2024-12-24; 1)

Returns: 25

Explanation: The function would normally return 24, however, we provided the optional second parameter to add 1 to the day, so the result is 25.
