Does it account for Daylight Saving Time?

Yes, our converter uses the IANA timezone database, which includes all current DST rules for every timezone in the world.

UTC (Coordinated Universal Time) is the primary time standard by which the world regulates clocks. All timezones are defined as offsets from UTC.

Can I compare multiple timezones at once?

Yes, you can add multiple cities or timezones and see the equivalent times side by side.

How many timezones are there in the world?

There are 38 distinct UTC offsets in use, ranging from UTC-12 to UTC+14. This includes half-hour (UTC+5:30 India, UTC+9:30 Australia) and 45-minute offsets (UTC+5:45 Nepal, UTC+8:45 Australia).

What is the International Date Line?

The International Date Line (IDL) runs roughly along the 180° meridian in the Pacific Ocean. When you cross it westward, you gain a day; crossing eastward, you lose a day.

Why do some timezones have 30 or 45 minute offsets?

Countries chose offsets that best matched their solar noon. India uses UTC+5:30 and Nepal uses UTC+5:45 because standard hourly offsets didn't align well with their geography.

Which country has the most timezones?

France has the most (12 timezones) due to overseas territories. Russia spans 11 timezones. The US has 6 (including Hawaii and Alaska).

Understanding the +5h Gap: EDT vs Nigeria

EDT runs on Eastern Daylight Time (EDT) at UTC-04:00. Nigeria runs on West Africa Time (WAT) at UTC+01:00. That puts EDT 5 hours ahead of Nigeria — a difference of +5h at the current offsets.

In practice, when it is 9:00 AM in EDT it is 2:00 PM in Nigeria. Midnight in EDT is 5:00 AM in Nigeria. Neither zone observes daylight saving time, so the offset between them stays constant all year.

Why people convert EDT to Nigeria time

Scheduling a call from EDT to Nigeria: a 10:00 AM start in EDT lands at 3:00 PM in Nigeria, so you can confirm the slot without doing the arithmetic yourself.
Finding shared working hours: both EDT and Nigeria are inside the 9-to-5 working day between 9:00 AM and 12:00 PM EDT time (2:00 PM–5:00 PM WAT). That is roughly 3 hours of usable overlap.
Coordinating a EDT-based team with Nigeria contacts: quoting times in the other side's local clock — not your own — removes the single biggest source of missed meetings.

Always state the zone abbreviation, not just the hour. "3:00 PM EDT" is unambiguous; "3 PM" across a +5h gap is not.
Block 9:00 AM–12:00 PM EDT as the recurring meeting window if you work primarily from EDT and need Nigeria colleagues present.

About EDT (Eastern Daylight Time)

Eastern Daylight Time (EDT) is used during the summer months (second Sunday of March to the first Sunday of November) in the Eastern Time Zone. During EDT, clocks are advanced by one hour to take advantage of longer daylight hours. Not all locations in the Eastern Time Zone observe DST – Panama, Jamaica, and most of the Caribbean remain on EST year-round.

About WAT (West Africa Time)

West Africa Time (WAT) is used across much of West and Central Africa, including Nigeria, the most populous country in Africa. WAT does not observe daylight saving time and shares the same offset as Central European Time (CET).

Best time to call between EDT and Nigeria

Both EDT and Nigeria sit inside the 9 AM – 5 PM working day between 9:00 AM–12:00 PM EDT, which is 2:00 PM–5:00 PM WAT. That gives roughly 3 hours of shared time — the safest window for a live call or meeting.

Business hours overlap

EDT and Nigeria overlap for about 3 hours during the working day — enough for meetings if you avoid the edges of the window.

EDT is 5 hours ahead of Nigeria (EDT UTC-04:00 → WAT UTC+01:00). The shared working window is 9:00 AM–12:00 PM EDT. Remember to re-check around daylight-saving transitions.
