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).

Comparing Time Zones: Nigeria and KST

Nigeria runs on West Africa Time (WAT) at UTC+01:00. KST runs on Korea Standard Time (KST) at UTC+09:00. That puts Nigeria 8 hours ahead of KST — a difference of +8h at the current offsets.

In practice, when it is 9:00 AM in Nigeria it is 5:00 PM in KST. Midnight in Nigeria is 8:00 AM in KST. Neither zone observes daylight saving time, so the offset between them stays constant all year.

Why people convert Nigeria to KST time

Scheduling a call from Nigeria to KST: a 10:00 AM start in Nigeria lands at 6:00 PM in KST, so you can confirm the slot without doing the arithmetic yourself.
Handling a +8h gap: Nigeria and KST have no overlap inside a normal 9-to-5 day, so real-time meetings need an early-morning or late-evening slot on one side. 9:00 AM in KST is 5:00 PM in Nigeria.
Watching a live event or market open: Nigeria viewers need 5:00 PM in KST to catch a 9:00 AM start there, and 4:00 PM if the event is anchored to Nigeria.

Always state the zone abbreviation, not just the hour. "3:00 PM WAT" is unambiguous; "3 PM" across a +8h gap is not.
With a +8h gap there is no shared 9-to-5 window, so alternate the early start: one week Nigeria takes the early slot, the next week KST does.

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).

About KST (Korea Standard Time)

Korea Standard Time (KST) is the time zone used in South Korea. It shares the same UTC offset as Japan Standard Time but is a distinct time zone. South Korea does not observe daylight saving time. Seoul, the capital, is a major global tech and business hub.

Best time to call between Nigeria and KST

With a +8h offset there is no overlap inside a normal 9 AM – 5 PM day. KST opens at 9:00 AM KST, which is 5:00 PM in Nigeria, so real-time calls need an early-morning or late-evening slot on one side.

Business hours overlap

Nigeria and KST have no shared working hours because of the +8h gap. Teams need to alternate early starts or rely on asynchronous handovers.

Nigeria is 8 hours ahead of KST (WAT UTC+01:00 → KST UTC+09:00). There is no shared 9-to-5 window, so plan around an early or late slot. Remember to re-check around daylight-saving transitions.
