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).

Indonesia vs CET: Offsets, DST and Best Call Times

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

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

Why people convert Indonesia to CET time

Scheduling a call from Indonesia to CET: a 10:00 AM start in Indonesia lands at 4:00 AM in CET, so you can confirm the slot without doing the arithmetic yourself.
Finding shared working hours: both Indonesia and CET are inside the 9-to-5 working day between 3:00 PM and 5:00 PM WIB time (9:00 AM–11:00 AM CET). That is roughly 2 hours of usable overlap.
Booking travel or deliveries: tracking CET local time against Indonesia keeps pickup windows and arrival estimates honest across the -6h offset.

Always state the zone abbreviation, not just the hour. "3:00 PM WIB" is unambiguous; "3 PM" across a -6h gap is not.
Block 3:00 PM–5:00 PM WIB as the recurring meeting window if you work primarily from Indonesia and need CET colleagues present.

About WIB (Western Indonesia Time)

Western Indonesia Time (WIB, Waktu Indonesia Barat) is one of Indonesia's three time zones, fixed at UTC+07:00 all year. It covers Java, Sumatra, West Kalimantan and the provinces around them — home to Jakarta, the country's capital and largest city, plus Surabaya and Bandung. Indonesia does not observe daylight saving time, so WIB never shifts. WIB shares its UTC+07:00 offset with Indochina Time (ICT) and Christmas Island Time, but is a distinct zone covering the western half of the Indonesian archipelago. The country's other zones are WITA (UTC+08:00) in the centre and WIT (UTC+09:00) in the east.

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 Indonesia and CET

Both Indonesia and CET sit inside the 9 AM – 5 PM working day between 3:00 PM–5:00 PM WIB, 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

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

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