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).

Why people convert Anchorage to Jakarta time

Scheduling a call from Anchorage to Jakarta: a 10:00 AM start in Anchorage lands at 1:00 AM in Jakarta the next day, so you can confirm the slot without doing the arithmetic yourself.
Handling a +15h gap: Anchorage and Jakarta have no overlap inside a normal 9-to-5 day, so real-time meetings need an early-morning or late-evening slot on one side. 9:00 AM in Jakarta is 12:00 AM in Anchorage.
Watching a live event or market open: Anchorage viewers need 12:00 AM in Jakarta to catch a 9:00 AM start there, and 9:00 AM if the event is anchored to Anchorage.

Always state the zone abbreviation, not just the hour. "3:00 PM AKDT" is unambiguous; "3 PM" across a +15h gap is not.
With a +15h gap there is no shared 9-to-5 window, so alternate the early start: one week Anchorage takes the early slot, the next week Jakarta does.
Anchorage: Clocks fall back on Sun, Nov 1, 2026. Re-check this page after that date because the offset changes and so does the +15h gap.

About AKST (Alaska Standard Time)

Alaska Standard Time (AKST) is used in nearly all of Alaska. Due to Alaska's vast geographic size, the Aleutian Islands use Hawaii-Aleutian Standard Time instead. During summer months, Alaska switches to Alaska Daylight Time (AKDT, UTC-08:00).

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.

Best time to call between Anchorage and Jakarta

With a +15h offset there is no overlap inside a normal 9 AM – 5 PM day. Jakarta opens at 9:00 AM WIB, which is 12:00 AM in Anchorage, so real-time calls need an early-morning or late-evening slot on one side.

Business hours overlap

Anchorage and Jakarta have no shared working hours because of the +15h gap. Teams need to alternate early starts or rely on asynchronous handovers.

Anchorage is 15 hours ahead of Jakarta (AKDT UTC-08:00 → WIB UTC+07:00). There is no shared 9-to-5 window, so plan around an early or late slot. Remember to re-check around daylight-saving transitions.
