Syntax/Parameters
Syntax
boolean = IsBusinessDay ( string date | qword date );
Parameters
date
A string or qword value as a well formatted date siting or a date-time value, respectively.
Return Value
Returns a boolean as TRUE, FALSE or -1. On failure, function returns -1. Use GetLastError or IsError to determine if an error occurred or if daylight savings time is not supported.
Remarks
The function tests the specified date for being a normal business day (Monday through Friday) and not being a Federal Holiday.
Since string date interpretation is automatic (SD_AMERICAN), use caution with ambiguous formats. For example, January 12, 2025 is represented is ISO-8601 “2025-01-12” but “2025-12-01” is also a valid date. The function will pick ISO-8601 if the value is ambiguous. See StringToDate for additional information.
