Business Hours and Holidays for Your Calendar

How to set the business hours and holiday dates for an Appointments calendar so Omnifox never offers a slot outside your hours.

Jul 11, 2026

Every Appointments calendar has its own business hours: the days and time windows in which slots can be booked. Outside of that window, the availability engine will never offer a slot, no matter how open the calendar looks otherwise.

Configuration

  • Business hours: a list of rules per day of the week (Sunday=0 … Saturday=6), each with an open time and a close time. You can add more than one window per day — e.g. 9:00–13:00 and 14:00–18:00 to keep lunchtime closed.
  • Holidays: specific dates (day/month/year) on which the calendar is fully closed, regardless of its usual business hours.
  • Time zone: the reference those hours are interpreted in (see the time zones article).
  • On Agent-type calendars, the business hours are also intersected with that agent's own shift schedule — only the overlap between both is ever offered.

Steps

  1. When creating or editing a calendar, set the windows per day (a new calendar defaults to Monday–Friday, 9:00–18:00).
  2. Add whichever holiday dates apply (year-end, national holidays, one-off closures).
  3. Save — changes apply immediately to any new slot search.

Example

A "Customer Care" calendar is open Monday–Friday 9:00–13:00 and 14:00–18:00, with Dec 25 and Jan 1 marked as holidays. On those dates the slot picker simply shows nothing, even if there's staff available that day.

Tips

  • If an agent works a split shift (morning and afternoon with a midday break), add two windows for that day instead of one 9:00–18:00 block.
  • Review holidays at the start of each year — they don't roll over automatically.

Troubleshooting

If a customer says "there's nothing available" on a day that should be open, check whether that date was added as a holiday, and — for Agent calendars — whether the agent's own shift is also open that day.
