Shared working hours
Taking a working day as 09:00–17:00 in each zone, West Africa Time and Eastern Time overlap for 3 hours.
2:00 PM–5:00 PM in WAT is 9:00 AM–12:00 PM in EST.
When the difference changes
The two zones move their clocks on different dates, so the gap takes more than one value. These are the stretches of 2026:
| Dates | EST is | Why |
|---|---|---|
| 1 January – 8 March | 6 hours behind | — |
| 8 March – 1 November | 5 hours behind | Eastern Time clocks go forward one hour |
| 1 November – 1 January | 6 hours behind | Eastern Time clocks go back one hour |
Dates are West Africa Time local dates for 2026. Transition dates move by a few days from year to year; the rule each country follows does not.

About West Africa Time
West Africa Time is a fixed UTC+1, covering Nigeria, Cameroon, Angola and their neighbours. It shares its offset with Central European standard time for five months of the year and sits an hour behind it for the other seven, without moving.
Cities on this clock: Lagos, Kinshasa, Algiers, Tunis.
About Eastern Time
Eastern Time is the most populous North American zone and the one most business hours are quoted in. It is UTC−5 as EST and UTC−4 as EDT. Because it changes on US dates rather than European ones, its gap to London and to Central Europe is not constant — there are two short stretches each year when it is an hour narrower than usual, and they are the reason this pair's table has more than one row.
Cities on this clock: New York, Philadelphia, Boston, Miami, Atlanta, Toronto, Montreal, Ottawa.
How the difference is worked out
The gap between West Africa Time and Eastern Time is not one number. The two zones change their clocks on different dates, so for part of the year the difference is 5 hours and for the rest it is something else — the table above lists each stretch of 2026 with the date it starts and which country's clocks moved.
With both zones on their own standard time — daylight saving not in force anywhere — Eastern Time is 6 hours behind West Africa Time. That figure never changes; everything else on this page follows from it plus whichever clocks have moved.
Every figure here comes from the IANA time zone database via your browser's own Intl engine, using the zone ids Africa/Lagos and America/New_York. Nothing is looked up on a server and nothing about your visit is recorded.
Is EST ahead of or behind WAT?
Eastern Time is 5 hours behind West Africa Time for 238 days of the year, and takes 2 different values across the year.
