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).

Comparing Time Zones: EAT and MDT

EAT runs on East Africa Time (EAT) at UTC+03:00. MDT runs on Mountain Daylight Time (MDT) at UTC-06:00. That puts EAT 9 hours behind MDT — a difference of -9h at the current offsets.

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

Why people convert EAT to MDT time

Scheduling a call from EAT to MDT: a 10:00 AM start in EAT lands at 1:00 AM in MDT, so you can confirm the slot without doing the arithmetic yourself.
Handling a -9h gap: EAT and MDT 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 MDT is 12:00 AM in EAT.
Watching a live event or market open: EAT viewers need 12:00 AM in MDT to catch a 9:00 AM start there, and 9:00 AM if the event is anchored to EAT.

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

About EAT (East Africa Time)

East Africa Time (EAT) is used in the countries of East Africa including Kenya, Ethiopia, Tanzania, Uganda, and others. EAT does not observe daylight saving time and shares the same offset as Moscow Standard Time (MSK).

About MDT (Mountain Daylight Time)

Mountain Daylight Time (MDT) is observed during summer months in the Mountain Time Zone, except in Arizona which stays on MST year-round. MDT aligns with Central Standard Time (CST) at UTC-06:00.

Best time to call between EAT and MDT

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

Business hours overlap

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

EAT is 9 hours behind MDT (EAT UTC+03:00 → MDT UTC-06:00). There is no shared 9-to-5 window, so plan around an early or late slot. Remember to re-check around daylight-saving transitions.
