Frequently asked questions
What is the time difference between GMT and WAT?
WAT is 1 hour ahead of GMT all year. Neither side uses daylight saving time, so the gap never changes.
What is 3 PM GMT in WAT time?
3 PM in GMT is 4 PM in WAT.
When do GMT and WAT working hours overlap?
On weekdays, a 9 AM to 5 PM day overlaps from 9 AM to 4 PM (GMT time). Use the meeting planner to stretch the day or add more cities.
Is WAT GMT+1?
Yes. WAT (West Africa Time) is GMT+1, also written UTC+1. It does not change during the year.
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 GMT and WAT
If both of you keep a 9 AM to 5 PM weekday, the shared window is 9 AM to 4 PM GMT 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.
