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 Casablanca to Japan time

Scheduling a call from Casablanca to Japan: a 10:00 AM start in Casablanca lands at 6:00 PM in Japan, so you can confirm the slot without doing the arithmetic yourself.
Handling a +8h gap: Casablanca and Japan 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 Japan is 5:00 PM in Casablanca.
Coordinating a Casablanca-based team with Japan 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 UTC+01:00" is unambiguous; "3 PM" across a +8h gap is not.
With a +8h gap there is no shared 9-to-5 window, so alternate the early start: one week Casablanca takes the early slot, the next week Japan does.
Casablanca: Clocks fall back on Sun, Feb 7, 2027. Re-check this page after that date because the offset changes and so does the +8h gap.
