GMT is the fixed reference that server logs, flight schedules, football kick-off listings and crypto exchanges often use. It never moves, so WAT is always exactly one hour ahead of it. That is not the same as UK time, which switches to BST in summer. Right now GMT is 1 hour behind WAT all year.

Frequently asked questions
What is the time difference between WAT and GMT?
GMT is 1 hour behind WAT all year. Neither side uses daylight saving time, so the gap never changes.
What is 3 PM WAT in GMT time?
3 PM in WAT is 2 PM in GMT.
When do WAT and GMT working hours overlap?
On weekdays, a 9 AM to 5 PM day overlaps from 10 AM to 5 PM (WAT time). Use the meeting planner to stretch the day or add more cities.
Is GMT the same as UK time?
Only in winter. GMT is fixed at UTC+0 all year. The UK uses GMT from late October to late March and BST (UTC+1) in summer. If you need London time, use the Lagos to London page.
Does this tool handle daylight saving time?
Yes. It uses your browser's built-in time zone database (the IANA database that phones and computers use), so summer and winter time changes are applied for the exact date you pick. Nigeria (WAT, UTC+1) never changes its clocks, but the US, Canada, the UK and Europe do, so the gap to them moves by one hour twice a year.
Best time to talk between WAT and GMT
If both of you keep a 9 AM to 5 PM weekday, the shared window is 10 AM to 5 PM WAT time. Put calls near the middle of it so nobody joins tired or rushed. Need three or four cities? Use the meeting planner. Want everyone to see the time in their own zone? Share your working-hours link.
