Follow-the-Sun Shift Planner
Add the teams that share your on-call or operations rota, give each a local shift window, and see the whole day in UTC: who is on, where shifts overlap for handover, and where nobody is watching.
Offsets use each zone's current UTC offset as computed by your browser, so daylight saving is handled automatically for today's date.
Teams
Shift start is local time. Length in hours. A one-hour overlap at each handover is the minimum that works in practice.
