From there, you can arrange cover yourself, or set up a policy to automatically flag any upcoming overlaps. ## Create an override To arrange cover for a holiday, hover over it in the timeline and click **Create override**. ## Detect on-call and vacation overlaps with a policy Nobody wants to get paged on the beach. A vacation policy checks upcoming vacations against your On-call schedules and notifies you of any overlaps, so they're spotted well before someone's already off. Here's how it works: * **We spot overlaps automatically.** We check upcoming vacations against who's scheduled to be on-call and surface any conflicts. * **We look 60 days ahead.** We scan for overlaps in the next 60 days, so there's time to arrange cover. * **We notify the person on vacation.** When we spot an overlap, we let them know so they can sort cover before they're off. Vacation overlaps are configured as a policy. To turn this on, see [Policies](/admin/policies).
