A holiday set is a special kind of shared schedule that can be used to specify days on which a job should not be run (using the settings on the Holidays page of the Schedule Trigger window).
adTempus comes preconfigured with the "Standard U.S. Holidays" set, which defines the following standard U.S. holidays:
New Year's Day (January 1)
Martin Luther King Day (Third Monday in January)
Presidents' Day (Third Monday in February)
Good Friday
Easter
Memorial Day (Last Monday in May)
Independence Day (July 4)
Labor Day (First Monday in September)
Columbus Day (Second Monday in October)
Veterans' Day (November 11)
Thanksgiving (Fourth Thursday in November)
Day After Thanksgiving
Christmas Day (December 25)
This set can be altered to match the holiday schedule of your organization, or you may create new holiday schedules.
Use the settings on the Security page to specify which users are allowed to use this set of holidays.
