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).

Why people convert Lagos to HST time

Scheduling a call from Lagos to HST: a 10:00 AM start in Lagos lands at 11:00 PM in HST the previous day, so you can confirm the slot without doing the arithmetic yourself.
Handling a -11h gap: Lagos and HST 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 HST is 10:00 PM in Lagos.
Booking travel or deliveries: tracking HST local time against Lagos keeps pickup windows and arrival estimates honest across the -11h offset.

Always state the zone abbreviation, not just the hour. "3:00 PM WAT" is unambiguous; "3 PM" across a -11h gap is not.
With a -11h gap there is no shared 9-to-5 window, so alternate the early start: one week Lagos takes the early slot, the next week HST 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 HST (Hawaii Standard Time)

Hawaii Standard Time (HST) is used in the state of Hawaii and does not observe daylight saving time. This makes HST one of the most consistent time zones in the US. The Hawaiian Islands are among the last places on Earth to see a new calendar day.

Best time to call between Lagos and HST

With a -11h offset there is no overlap inside a normal 9 AM – 5 PM day. HST opens at 9:00 AM HST, which is 10:00 PM in Lagos, so real-time calls need an early-morning or late-evening slot on one side.

Business hours overlap

Lagos and HST have no shared working hours because of the -11h gap. Teams need to alternate early starts or rely on asynchronous handovers.

Lagos is 11 hours behind HST (WAT UTC+01:00 → HST UTC-10:00). There is no shared 9-to-5 window, so plan around an early or late slot. Remember to re-check around daylight-saving transitions.
