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: PDT to CAT

PDT runs on Pacific Daylight Time (PDT) at UTC-07:00. CAT runs on Central Africa Time (CAT) at UTC+02:00. That puts PDT 9 hours ahead of CAT — a difference of +9h at the current offsets.

In practice, when it is 9:00 AM in PDT it is 6:00 PM in CAT. Midnight in PDT is 9:00 AM in CAT. Neither zone observes daylight saving time, so the offset between them stays constant all year.

Why people convert PDT to CAT time

Scheduling a call from PDT to CAT: a 10:00 AM start in PDT lands at 7:00 PM in CAT, so you can confirm the slot without doing the arithmetic yourself.
Handling a +9h gap: PDT and CAT 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 CAT is 6:00 PM in PDT.
Coordinating a PDT-based team with CAT 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 PDT" 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 PDT takes the early slot, the next week CAT does.

About PDT (Pacific Daylight Time)

Pacific Daylight Time (PDT) is observed from March to November on the Pacific coast. During PDT, the west coast is 7 hours behind UTC and only 2 hours behind the east coast's EDT.

About CAT (Central Africa Time)

Central Africa Time (CAT) is fixed at UTC+02:00 all year across a broad belt of southern and central Africa, including Zimbabwe, Zambia, Mozambique, Malawi, Rwanda, Burundi and the eastern Democratic Republic of the Congo. None of these countries observes daylight saving time, so CAT never shifts. It is the same offset as South Africa Standard Time (SAST) and the winter version of Central European Time, which makes CAT a convenient bridge between African, European and Middle Eastern schedules — Harare is level with Johannesburg all year and one hour ahead of Lagos.

Best time to call between PDT and CAT

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

Business hours overlap

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

PDT is 9 hours ahead of CAT (PDT UTC-07:00 → CAT UTC+02:00). There is no shared 9-to-5 window, so plan around an early or late slot. Remember to re-check around daylight-saving transitions.
