How to use this on-call schedule generator

  1. Paste your team in the order you want them to rotate — one name per line or comma separated.
  2. Choose a cadence. Weekly is the most common on-call rotation; daily suits support queues; "every N days" covers follow-the-sun or fortnightly schedules.
  3. Set the handoff time and start date, then export: .ics for Google Calendar, Outlook, or Apple Calendar, CSV for a spreadsheet, or Copy as Slack message to post it in your team channel.

Why a rotation schedule template breaks after a month

A generated on-call rotation is a great start, but the schedule you export today is static. The first vacation, swap, or new hire means regenerating it, re-importing the calendar, and reminding everyone which version is current.

Sched keeps the rotation live inside Slack: it hands off on schedule, DMs the outgoing and incoming person, keeps your @oncall user group in sync, and lets people swap shifts without leaving Slack. See the free on-call schedule page for what the free tier includes.
