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).

ICT vs CET: Offsets, DST and Best Call Times

ICT runs on Indochina Time (ICT) at UTC+07:00. CET runs on Central European Time (CET) at UTC+01:00. That puts ICT 6 hours behind CET — a difference of -6h at the current offsets.

In practice, when it is 9:00 AM in ICT it is 3:00 AM in CET. Midnight in ICT is 6:00 PM in CET. Neither zone observes daylight saving time, so the offset between them stays constant all year.

Why people convert ICT to CET time

Scheduling a call from ICT to CET: a 10:00 AM start in ICT lands at 4:00 AM in CET, so you can confirm the slot without doing the arithmetic yourself.
Finding shared working hours: both ICT and CET are inside the 9-to-5 working day between 3:00 PM and 5:00 PM ICT time (9:00 AM–11:00 AM CET). That is roughly 2 hours of usable overlap.
Keeping family and friends in sync: knowing that 8:00 PM in ICT is 2:00 PM in CET makes it easy to avoid calling at 3 AM.

Always state the zone abbreviation, not just the hour. "3:00 PM ICT" is unambiguous; "3 PM" across a -6h gap is not.
Block 3:00 PM–5:00 PM ICT as the recurring meeting window if you work primarily from ICT and need CET 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 CET (Central European Time)

Central European Time (CET) is the standard time zone for most of Europe, covering over 30 countries from Spain to Poland, and from Norway to Italy. CET is 1 hour ahead of GMT and is used by the European Union's most populous nations. During summer, most CET countries switch to Central European Summer Time (CEST, UTC+02:00). Major European financial markets in Frankfurt, Paris, and Amsterdam operate on CET.

Best time to call between ICT and CET

Both ICT and CET sit inside the 9 AM – 5 PM working day between 3:00 PM–5:00 PM ICT, which is 9:00 AM–11:00 AM CET. That gives roughly 2 hours of shared time — the safest window for a live call or meeting.

Business hours overlap

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

ICT is 6 hours behind CET (ICT UTC+07:00 → CET UTC+01:00). The shared working window is 3:00 PM–5:00 PM ICT. Remember to re-check around daylight-saving transitions.
