Holiday Calendars
Holiday Calendars are shared sets of dates referenced by Access Control rules. On a date that appears in an assigned calendar, the rule will not grant access — regardless of its day/hour schedule.
The point of a calendar is to maintain holidays and shutdowns in one place and reference them from many rules, instead of duplicating per-rule exception lists.
Overview
A holiday calendar contains:
- A name (lowercase identifier) and label (human-readable)
- A list of date entries — either a single date (
2026-12-25) or a date range (from–to, inclusive on both ends)
Multiple access control rules can reference the same calendar.
Creating a Calendar
- Open Security > Holiday Calendars
- Click Add
- Fill in name + label
- Add individual dates and/or date ranges
- Save
Examples
US Federal Holidays
Name: us_federal_holidays
Label: US Federal Holidays
Dates: 2026-01-01, 2026-01-19, 2026-02-16, 2026-05-25, …
Office Shutdown
Name: office_shutdown
Label: Office Year-End Shutdown
Dates: { from: 2026-12-24, to: 2027-01-02 }
Using a Calendar
In an access control rule's Schedule Configuration > Holiday Calendar dropdown, select the calendar to apply.
- A calendar match wins over the rule's day/hour mask — if today is in the calendar, access is denied even if the day/hour would otherwise allow it
- The rule's per-rule Schedule Exceptions list is still honored alongside the calendar (denied if either matches)
Managing Calendars
- Edit a calendar to add or remove dates — changes take effect immediately for all rules referencing it
- Deleting a calendar leaves rules pointing at
null— they fall back to per-rule exceptions only - A calendar with no dates blocks no days
