Clock change alert for anyone scheduling between Nigeria and the US. Nigeria stays on West Africa Time (UTC+1) all year. The US moves its clocks back this Sunday, 1 November. The gap changes: • New York: 5 hours behind Lagos now, 6 hours from 1 November • Los Angeles: 8 hours behind now, 9 hours from 1 November.

A recurring 9:00 AM New York call is 2:00 PM in Lagos today and 3:00 PM from next week. Nobody changed the meeting.

The clocks did. My checklist for a clock-change week:

1. Review every recurring meeting with US attendees through early November.

2. Confirm times in writing with both zones: "9:00 AM ET / 3:00 PM WAT".

3. Check the calendar's time zone setting. In Google Calendar, you can also display a secondary time zone.

4. Resend reminders for early-morning slots.

Other regions change their clocks on different dates, so check the ones that matter to your team.
