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 EEST to Santiago time

Scheduling a call from EEST to Santiago: a 10:00 AM start in EEST lands at 4:00 AM in Santiago, so you can confirm the slot without doing the arithmetic yourself.
Finding shared working hours: both EEST and Santiago are inside the 9-to-5 working day between 3:00 PM and 5:00 PM EEST time (9:00 AM–11:00 AM CLST). That is roughly 2 hours of usable overlap.
Coordinating a EEST-based team with Santiago 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 EEST" is unambiguous; "3 PM" across a -6h gap is not.
Block 3:00 PM–5:00 PM EEST as the recurring meeting window if you work primarily from EEST and need Santiago colleagues present.
Santiago: Clocks fall back on Sun, Apr 4, 2027. Any meeting series spanning that date will shift by an hour in local time.

About EEST (Eastern European Summer Time)

Eastern European Summer Time (EEST) is the daylight saving period used across eastern Europe, when clocks move one hour forward from Eastern European Time (EET, UTC+02:00) to UTC+03:00. It runs from the last Sunday in March to the last Sunday in October, in step with the rest of the European Union. EEST covers Greece, Finland, Romania, Bulgaria, the Baltic states, Ukraine and Moldova, and matches the offset used year-round by Moscow, Istanbul and Riyadh during those months. Athens and Helsinki both sit near the western edge of the EEST band, so summer evenings stay light well past 21:00.

About CLT (Chile Standard Time)

Chile Standard Time (CLT) is the standard time in Chile. During summer months (October to March), Chile switches to Chile Summer Time (CLST, UTC-03:00). Chile is the longest north-south country in the world.

Business hours overlap

EEST and Santiago overlap for about 2 hours during the working day — enough for meetings if you avoid the edges of the window.

EEST is 6 hours behind Santiago (EEST UTC+03:00 → CLST UTC-03:00). The shared working window is 3:00 PM–5:00 PM EEST. Remember to re-check around daylight-saving transitions.
