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.

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).

Key Facts about WIB

•Indonesia spans three time zones: WIB (UTC+07:00), WITA (UTC+08:00) and WIT (UTC+09:00).
•Indonesia has not observed daylight saving time since 1964.
•Jakarta is the largest city in Southeast Asia by population.
•WIB shares the UTC+07:00 offset with Indochina Time.

UTC – Coordinated Universal Time

UTC+00:00

Coordinated Universal Time (UTC) is the world's primary time standard, used as the basis for civil time worldwide.

Key Facts about UTC

•UTC is the basis for all civil time zones worldwide.
•The abbreviation 'UTC' is a compromise between English (CUT) and French (TUC).
•UTC is based on atomic clocks and is accurate to within a nanosecond per day.
•Servers and databases worldwide store timestamps in UTC to avoid timezone confusion.
•Leap seconds are occasionally added to UTC to keep it aligned with Earth's rotation.

Understanding the -7h Gap: Indonesia vs UTC

Indonesia runs on Western Indonesia Time (WIB) at UTC+07:00. UTC runs on Coordinated Universal Time (UTC) at UTC+00:00. That puts Indonesia 7 hours behind UTC — a difference of -7h at the current offsets.

In practice, when it is 9:00 AM in Indonesia it is 2:00 AM in UTC. Midnight in Indonesia is 5:00 PM in UTC. Neither zone observes daylight saving time, so the offset between them stays constant all year.

Why people convert Indonesia to UTC time

Scheduling a call from Indonesia to UTC: a 10:00 AM start in Indonesia lands at 3:00 AM in UTC, so you can confirm the slot without doing the arithmetic yourself.
Finding shared working hours: both Indonesia and UTC are inside the 9-to-5 working day between 4:00 PM and 5:00 PM WIB time (9:00 AM–10:00 AM UTC). That is roughly 1 hours of usable overlap.
Watching a live event or market open: Indonesia viewers need 2:00 AM in UTC to catch a 9:00 AM start there, and 7:00 AM if the event is anchored to Indonesia.

Always state the zone abbreviation, not just the hour. "3:00 PM WIB" is unambiguous; "3 PM" across a -7h gap is not.
Block 4:00 PM–5:00 PM WIB as the recurring meeting window if you work primarily from Indonesia and need UTC 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 UTC (Coordinated Universal Time)

Coordinated Universal Time (UTC) is the primary time standard by which the world regulates clocks and time. It is effectively the successor to GMT and is based on International Atomic Time with leap seconds added to keep it synchronized with Earth's rotation. UTC is used in aviation, computing, navigation, weather forecasting, and the International Space Station. Most programming languages and databases store timestamps in UTC.

Best time to call between Indonesia and UTC

Both Indonesia and UTC sit inside the 9 AM – 5 PM working day between 4:00 PM–5:00 PM WIB, which is 9:00 AM–10:00 AM UTC. That gives roughly 1 hours of shared time — the safest window for a live call or meeting.

Business hours overlap

Indonesia and UTC overlap for only 60 minutes (4:00 PM–5:00 PM WIB), so meetings have to be booked precisely.

Indonesia is 7 hours behind UTC (WIB UTC+07:00 → UTC UTC+00:00). The shared working window is 4:00 PM–5:00 PM WIB. Remember to re-check around daylight-saving transitions.
