Arguments

ArgumentTypeDescription

to_dateDate or Number (date serial)An expression representing the second date value to derive the number of workdays from.

Return value type: Number


Remarks

The from_date and to_date arguments can take any value or expression that evaluates to a date serial value. Examples include:

  • A date literal: #2019-12-12
  • A date serial value: 43811 (the date serial for "2019-12-12")
  • A date value created using any of the Date/Time functions that returns a date serial value.

The exclude and include arguments need to be a date or list of dates, delimited by commas, enclosed in quotes, and appearing in yyyy-MM-dd format:

  • A single date: "2024-02-20"
  • List of 3 dates: "2023-04-01, 2023-07-22, 2023-10-31"
  • Use empty quotes ("") in the exclude_dates position if no dates will be excluded, but there are dates to be included. See the last Example below.
  • A date serial value cannot be used (i.e., "43811").
