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).

PST to WAT Time Difference – Complete Guide

Why people convert PST to WAT time

Scheduling a call from PST to WAT: a 10:00 AM start in PST lands at 7:00 PM in WAT, so you can confirm the slot without doing the arithmetic yourself.
Handling a +9h gap: PST and WAT 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 WAT is 6:00 PM in PST.
Keeping family and friends in sync: knowing that 8:00 PM in PST is 5:00 AM in WAT makes it easy to avoid calling at 3 AM.

Always state the zone abbreviation, not just the hour. "3:00 PM PST" 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 PST takes the early slot, the next week WAT does.

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.

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 PST and WAT

With a +9h offset there is no overlap inside a normal 9 AM – 5 PM day. WAT opens at 9:00 AM WAT, which is 6:00 PM in PST, so real-time calls need an early-morning or late-evening slot on one side.

Business hours overlap

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

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