More Control Over When People Can Book Your Calendars

Each scheduling calendar now has Booking Rules and Date Overrides, so you can decide how soon and how far ahead people can book, and close or change your hours on specific dates.

What changed

Before

Bookings were always limited to 60 days ahead, and any open time could be booked, even if it started minutes later.

There was no way to close a calendar on a specific date or change its hours for one day.

Now

You set how much notice a booking needs and how far ahead people can book, for each calendar.

You can also block specific dates or give them custom hours, for one calendar or for your whole organization.

What’s in your calendar settings

Booking Rules

A new Booking Rules section on a calendar’s Settings tab sits between Weekly Hours and Event Limits, and saves with Save Settings.

  • Minimum scheduling notice. Set how far in advance a booking must be made, in minutes, hours, or days. People can’t book times sooner than that, and the booking page tells them how much notice is needed.
  • Booking horizon. Choose a rolling window, counted in calendar days or in days the calendar has hours, or allow booking indefinitely into the future, up to a maximum of 365 days. Existing calendars keep their current 60-day window until you change it.
  • Clearer daily limits. Your existing per-day booking limits work the same way, but the booking page now explains when a day is fully booked.

The minimum notice can’t be longer than the booking window.

Booking Rules settings: a minimum scheduling notice of 3 days, and a booking horizon set to Rolling window with a 30 calendar day booking window. The other horizon option is Indefinitely into the future, capped at 365 days.
Set the minimum notice and how far ahead people can book.

Date Overrides

A new Date Overrides card appears after Weekly Hours on the Settings tab.

  • Block a date or set custom hours. Close a calendar for a specific date, or give that date different hours from your usual weekly schedule.
  • Organization-wide closures. Mark a date, such as a holiday, as closed for all of your calendars at once. If a calendar has its own override for that date, the calendar’s override is used.
  • See it at a glance. A month view shows blocked dates and custom hours, and an Upcoming overrides list shows whether each one applies to the whole organization or just this calendar.
  • Existing bookings are never canceled. If you block a date that already has bookings, you’ll see a warning with how many there are, so you can review and reschedule them from the calendar.

Who these rules apply to

Booking Rules and Date Overrides apply when people book from a case scheduling link or your public booking page.

Staff booking inside Doobert aren’t held to the minimum notice, booking window, or blocked dates. Instead, they see a warning and can choose to book anyway. Double-booking a time that’s already taken is always prevented, for everyone.

Why it matters

You get time to prepare before each appointment, you control how far ahead your schedule opens, and holidays or closures no longer show up as open times.
