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).

Understanding the +2h Gap: WIB vs Tokyo

WIB runs on Western Indonesia Time (WIB) at UTC+07:00. Tokyo runs on Japan Standard Time (JST) at UTC+09:00. That puts WIB 2 hours ahead of Tokyo — a difference of +2h at the current offsets.

In practice, when it is 9:00 AM in WIB it is 11:00 AM in Tokyo. Midnight in WIB is 2:00 AM in Tokyo. Neither zone observes daylight saving time, so the offset between them stays constant all year.

Why people convert WIB to Tokyo time

Scheduling a call from WIB to Tokyo: a 10:00 AM start in WIB lands at 12:00 PM in Tokyo, so you can confirm the slot without doing the arithmetic yourself.
Finding shared working hours: both WIB and Tokyo are inside the 9-to-5 working day between 9:00 AM and 3:00 PM WIB time (11:00 AM–5:00 PM JST). That is roughly 6 hours of usable overlap.
Watching a live event or market open: WIB viewers need 11:00 AM in Tokyo to catch a 9:00 AM start there, and 10:00 PM if the event is anchored to WIB.

Always state the zone abbreviation, not just the hour. "3:00 PM WIB" is unambiguous; "3 PM" across a +2h gap is not.
Block 9:00 AM–3:00 PM WIB as the recurring meeting window if you work primarily from WIB and need Tokyo 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 JST (Japan Standard Time)

Japan Standard Time (JST) is the standard time zone for all of Japan. Japan does not observe daylight saving time. JST is 9 hours ahead of UTC and 14 hours ahead of EST. The Tokyo Stock Exchange, the world's third largest by market capitalization, operates on JST. South Korea uses the same offset (KST) but it is a distinct time zone.
