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 WAT to PST time

Scheduling a call from WAT to PST: a 10:00 AM start in WAT lands at 1:00 AM in PST, so you can confirm the slot without doing the arithmetic yourself.
Handling a -9h gap: WAT and PST 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 PST is 12:00 AM in WAT.
Coordinating a WAT-based team with PST 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 -9h gap is not.
With a -9h gap there is no shared 9-to-5 window, so alternate the early start: one week WAT takes the early slot, the next week PST 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 PST (Pacific Standard Time)

Pacific Standard Time (PST) covers the west coast of North America, including tech hubs like San Francisco and Seattle, and entertainment capital Los Angeles. The Pacific Time Zone is home to Silicon Valley and the world's largest technology companies. During summer, clocks advance to Pacific Daylight Time (PDT, UTC-07:00). PST is also observed in Baja California, Mexico.

Best time to call between WAT and PST

With a -9h offset there is no overlap inside a normal 9 AM – 5 PM day. PST opens at 9:00 AM PST, which is 12:00 AM in WAT, so real-time calls need an early-morning or late-evening slot on one side.

Business hours overlap

WAT and PST have no shared working hours because of the -9h gap. Teams need to alternate early starts or rely on asynchronous handovers.

WAT is 9 hours behind PST (WAT UTC+01:00 → PST UTC-08:00). There is no shared 9-to-5 window, so plan around an early or late slot. Remember to re-check around daylight-saving transitions.
