# On-call schedules

- [Introduction to On-call schedules](https://docs.spike.sh/oncall-schedules/introduction-to-on-call-schedules.md): On-call schedules define who is on-call and when. Members rotate automatically on daily, weekly, or custom intervals.
- [Create On-call schedule](https://docs.spike.sh/oncall-schedules/create-on-call-schedule.md): Set up an on-call schedule to define who's on-call and when across your team.
- [Slots in schedules](https://docs.spike.sh/oncall-schedules/introduction-to-slots-in-schedules.md): Slots restrict on-call coverage to specific hours or days, so team members aren't on-call around the clock.
- [Layers in on-call schedules](https://docs.spike.sh/oncall-schedules/introduction-to-layers-in-on-call-schedules.md): Layers let you stack multiple on-call configurations within a single schedule. When two layers overlap, the higher-numbered layer takes over.
- [Override an on-call](https://docs.spike.sh/oncall-schedules/override-an-on-call.md): On-call overrides assign temporary coverage for a shift without changing the underlying schedule.
- [Notifications for on-call shifts](https://docs.spike.sh/oncall-schedules/notifications-for-on-call-shifts.md): Spike sends notifications when your on-call shift starts or ends, across personal and team-wide channels.
- [Change on-call rotation day](https://docs.spike.sh/oncall-schedules/change-on-call-rotation-day.md): Change the rotation day on a weekly on-call schedule without losing coverage or disrupting the rotation order.
- [Sync with your calendar](https://docs.spike.sh/oncall-schedules/calendar-sync-for-oncall.md): Sync your on-call schedule to Google Calendar, Apple Calendar, Outlook, or any calendar app that supports subscriptions.
- [Google Calendar](https://docs.spike.sh/oncall-schedules/calendar-sync-for-oncall/google-calendar-sync.md): Sync your on-call schedule with your Google Calendar
- [Apple Calendar](https://docs.spike.sh/oncall-schedules/calendar-sync-for-oncall/apple-calendar-sync.md): Sync your on-call schedule with your Apple Calendar
- [Microsoft Outlook](https://docs.spike.sh/oncall-schedules/calendar-sync-for-oncall/microsoft-outlook-sync.md): Sync your on-call schedule with your Microsoft Outlook
- [Linked calendars](https://docs.spike.sh/oncall-schedules/linked-calendars.md): Add external or holiday calendars as overlays on your on-call schedule to plan shifts around holidays and team events.
