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).

Everything You Need to Know About ICT and CEST Time

ICT runs on Indochina Time (ICT) at UTC+07:00. CEST runs on Central European Summer Time (CEST) at UTC+02:00. That puts ICT 5 hours behind CEST — a difference of -5h at the current offsets.

In practice, when it is 9:00 AM in ICT it is 4:00 AM in CEST. Midnight in ICT is 7:00 PM in CEST. Neither zone observes daylight saving time, so the offset between them stays constant all year.

Why people convert ICT to CEST time

Scheduling a call from ICT to CEST: a 10:00 AM start in ICT lands at 5:00 AM in CEST, so you can confirm the slot without doing the arithmetic yourself.
Finding shared working hours: both ICT and CEST are inside the 9-to-5 working day between 2:00 PM and 5:00 PM ICT time (9:00 AM–12:00 PM CEST). That is roughly 3 hours of usable overlap.
Coordinating a ICT-based team with CEST 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 ICT" is unambiguous; "3 PM" across a -5h gap is not.
Block 2:00 PM–5:00 PM ICT as the recurring meeting window if you work primarily from ICT and need CEST colleagues present.

About ICT (Indochina Time)

Indochina Time (ICT) is used across Southeast Asia including Vietnam, Thailand, Laos, and Cambodia. Indonesia (Western time, WIB) also uses UTC+07:00. ICT does not observe daylight saving time.

About CEST (Central European Summer Time)

Central European Summer Time (CEST) is observed from the last Sunday of March to the last Sunday of October across most of Europe. During CEST, clocks are 2 hours ahead of UTC. The EU has debated abolishing seasonal clock changes since 2019.

Best time to call between ICT and CEST

Both ICT and CEST sit inside the 9 AM – 5 PM working day between 2:00 PM–5:00 PM ICT, which is 9:00 AM–12:00 PM CEST. That gives roughly 3 hours of shared time — the safest window for a live call or meeting.

Business hours overlap

ICT and CEST overlap for about 3 hours during the working day — enough for meetings if you avoid the edges of the window.

ICT is 5 hours behind CEST (ICT UTC+07:00 → CEST UTC+02:00). The shared working window is 2:00 PM–5:00 PM ICT. Remember to re-check around daylight-saving transitions.
