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).

Time Conversion Guide: WAT to GST

WAT runs on West Africa Time (WAT) at UTC+01:00. GST runs on Gulf Standard Time (GST) at UTC+04:00. That puts WAT 3 hours ahead of GST — a difference of +3h at the current offsets.

In practice, when it is 9:00 AM in WAT it is 12:00 PM in GST. Midnight in WAT is 3:00 AM in GST. Neither zone observes daylight saving time, so the offset between them stays constant all year.

Why people convert WAT to GST time

Scheduling a call from WAT to GST: a 10:00 AM start in WAT lands at 1:00 PM in GST, so you can confirm the slot without doing the arithmetic yourself.
Finding shared working hours: both WAT and GST are inside the 9-to-5 working day between 9:00 AM and 2:00 PM WAT time (12:00 PM–5:00 PM GST). That is roughly 5 hours of usable overlap.
Watching a live event or market open: WAT viewers need 12:00 PM in GST to catch a 9:00 AM start there, and 9:00 PM if the event is anchored to WAT.

Always state the zone abbreviation, not just the hour. "3:00 PM WAT" is unambiguous; "3 PM" across a +3h gap is not.
Block 9:00 AM–2:00 PM WAT as the recurring meeting window if you work primarily from WAT and need GST colleagues present.

Business hours overlap

WAT and GST share 5 hours of working-hours overlap (9:00 AM–2:00 PM WAT), so scheduling a live meeting is straightforward.

WAT is 3 hours ahead of GST (WAT UTC+01:00 → GST UTC+04:00). The shared working window is 9:00 AM–2:00 PM WAT. Remember to re-check around daylight-saving transitions.
