Frequently asked questions

How do I convert WAT to EST?

Subtract 6 hours in winter (early November to mid-March), when New York is on EST. Subtract 5 hours the rest of the year, when it is on EDT. So 3 PM WAT is 9 AM EST in January and 10 AM EDT in July. The converter picks the right one for your date.

What is the difference between EST and ET?

ET (Eastern Time) is the clock in New York, Atlanta and Toronto. It is EST (UTC−5) in winter and EDT (UTC−4) in summer. Many people write "EST" all year, so if a US client says EST in July they almost always mean EDT.

Is the converter accurate for future dates?

Yes. It uses the time zone rules built into your phone or computer, which include the dates clocks change in each country. If a country changes its rules, your device's next update brings the new ones.

Does it work offline?

Once the page has loaded, the conversions run on your device, so they keep working with a weak connection. Nothing you enter is sent to a server.

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.

What’s inside

Why the time difference keeps changing

Nigeria stays on UTC+1 all year. The US, Canada, the UK and Europe move their clocks forward in spring and back in autumn, and not on the same weekend: the US changes on the second Sunday of March and the first Sunday of November, while the UK and EU change on the last Sundays of March and October. That is why “New York is 5 hours behind” is only true for part of the year. The converter checks the exact date for you.
