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: WAT and HKT

WAT runs on West Africa Time (WAT) at UTC+01:00. HKT runs on Hong Kong Time (HKT) at UTC+08:00. That puts WAT 7 hours ahead of HKT — a difference of +7h at the current offsets.

In practice, when it is 9:00 AM in WAT it is 4:00 PM in HKT. Midnight in WAT is 7:00 AM in HKT. Neither zone observes daylight saving time, so the offset between them stays constant all year.

Why people convert WAT to HKT time

Scheduling a call from WAT to HKT: a 10:00 AM start in WAT lands at 5:00 PM in HKT, so you can confirm the slot without doing the arithmetic yourself.
Finding shared working hours: both WAT and HKT are inside the 9-to-5 working day between 9:00 AM and 10:00 AM WAT time (4:00 PM–5:00 PM HKT). That is roughly 1 hours of usable overlap.
Coordinating a WAT-based team with HKT 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 WAT" is unambiguous; "3 PM" across a +7h gap is not.
Block 9:00 AM–10:00 AM WAT as the recurring meeting window if you work primarily from WAT and need HKT colleagues present.

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 HKT (Hong Kong Time)

Hong Kong Time (HKT) is fixed at UTC+08:00 all year and does not observe daylight saving time. Hong Kong last used summer time in 1979 and has kept a single offset since. HKT shares the UTC+08:00 offset with China Standard Time, Singapore Time, Malaysian Time, Philippine Time and Australian Western Standard Time, but is listed separately because Hong Kong maintains its own timekeeping authority. As a major financial centre, Hong Kong's trading hours set the rhythm for markets across Asia, opening at 09:30 HKT which is 01:30 in London and 20:30 the previous evening in New York.

Best time to call between WAT and HKT

Both WAT and HKT sit inside the 9 AM – 5 PM working day between 9:00 AM–10:00 AM WAT, which is 4:00 PM–5:00 PM HKT. That gives roughly 1 hours of shared time — the safest window for a live call or meeting.

Business hours overlap

WAT and HKT overlap for only 60 minutes (9:00 AM–10:00 AM WAT), so meetings have to be booked precisely.

WAT is 7 hours ahead of HKT (WAT UTC+01:00 → HKT UTC+08:00). The shared working window is 9:00 AM–10:00 AM WAT. Remember to re-check around daylight-saving transitions.
