Business Hours Calendars

A business hours calendar says when you are open. The same calendar can be used by:

• a queue, to hold or overflow callers while closed;
• an inbound entry point, to pick the closed action (voicemail, overflow, reject);
• a dialer profile, as the outbound calling window, checked in the contact's time zone;
• an automatic activity load, so AI follow-up messages are only sent while open.

Permission	Manage Contact Center business hours
Feature	Contact Center Business Hours (CrestApps.OrchardCore.ContactCenter.BusinessHours), enabled automatically by the features that use it

Create a calendar

1. Open Interaction Center > Management > Business hours and click Add calendar.
2. Enter a Name such as Support hours and an optional Description.
3. Pick the Time zone the hours are written in. Empty means UTC.
4. In Weekly schedule, tick Open for each open day and set From and To. A new calendar starts with Monday to Friday, 09:00 to 17:00.
5. In Holidays, enter one date per line in the form 2026-12-25. The calendar is closed all day on those dates.
6. Leave Enabled ticked and click Save.

Rules worth knowing

• The To time is exclusive: 09:00 to 17:00 closes at exactly 17:00.
• The same From and To time means open for 24 hours.
• A To time earlier than From runs past midnight, for example 22:00 to 06:00.
• Holiday lines that are not valid dates are ignored, so check the list after saving.
• A disabled calendar never closes anything: every queue that uses it is treated as always open.
