Category: Date and Time function

This function returns the number of workdays (i.e. all days except the two weekend days, which are Saturday and Sunday unless weekend_start says otherwise) between from_date and to_date. Both date boundaries are inclusive.

Return value type: Number

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 position if no dates will be excluded, but there are dates to be included.
• Use empty quotes in both positions to specify weekend_start without excluding or including any dates.
• A date serial value cannot be used (i.e., "43811").
