Holiday Aware Task Scheduler

In Advanced Task Scheduler Professional and Network Edition you can run tasks on holidays, or avoid running tasks on holidays.

If you wish to start a task on either a single holiday or all holidays, you can use the "Run on holiday" schedule type with the "Run on the day of holiday" option.
If you wish to start a task on all days except either a single holiday or all holidays, you can use the "Run on holiday" schedule type with the "Run on all days except holiday" option.
If you wish to start a task on work days only, excluding holidays and non-work days such as Saturday and Sunday, you can use the "Run weekly" schedule type with the "Work days only" option selected.
If you wish to start a task on non-work days only, including holidays and non-work days such as Saturday and Sunday, you can use the "Run weekly" schedule type with the "Non-work days only" option selected.
If you wish to set up work days and holidays, go to the "Holidays" section on the user's tab of the "Preferences" window.
If you wish to preview days when the task will start in the future, you can use the "View start time" button on the "Schedule" tab of the "Task Properties" window.
