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 Istanbul to Addis Ababa time

Scheduling a call from Istanbul to Addis Ababa: a 10:00 AM start in Istanbul lands at 10:00 AM in Addis Ababa, so you can confirm the slot without doing the arithmetic yourself.
Finding shared working hours: both Istanbul and Addis Ababa are inside the 9-to-5 working day between 9:00 AM and 5:00 PM TRT time (9:00 AM–5:00 PM EAT). That is roughly 8 hours of usable overlap.
Coordinating a Istanbul-based team with Addis Ababa 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 TRT" is unambiguous; "3 PM" across a +0h gap is not.
Block 9:00 AM–5:00 PM TRT as the recurring meeting window if you work primarily from Istanbul and need Addis Ababa colleagues present.

About TRT (Turkey Time)

Turkey Time (TRT) is fixed at UTC+03:00 all year. Turkey abolished seasonal clock changes in September 2016, moving to a permanent UTC+03:00 so the whole country stays on what was formerly summer time. That leaves Istanbul, which sits close to 29°E, on an offset well ahead of its solar time — sunrise in mid-winter comes after 08:30 local. TRT shares its offset with Moscow Standard Time, Arabia Standard Time and East Africa Time, so Istanbul is level with Moscow and Riyadh all year and one hour ahead of Central European Time during the European winter.

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).
