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 to AKST Time Difference – Complete Guide

Indonesia runs on Western Indonesia Time (WIB) at UTC+07:00. AKST runs on Alaska Standard Time (AKST) at UTC-09:00. That puts Indonesia 16 hours behind AKST — a difference of -16h at the current offsets.

In practice, when it is 9:00 AM in Indonesia it is 5:00 PM in AKST on the previous day. Midnight in Indonesia is 8:00 AM in AKST. Neither zone observes daylight saving time, so the offset between them stays constant all year.

Why people convert Indonesia to AKST time

Scheduling a call from Indonesia to AKST: a 10:00 AM start in Indonesia lands at 6:00 PM in AKST the previous day, so you can confirm the slot without doing the arithmetic yourself.
Handling a -16h gap: Indonesia and AKST 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 AKST is 5:00 PM in Indonesia.
Watching a live event or market open: Indonesia viewers need 5:00 PM in AKST to catch a 9:00 AM start there, and 4:00 PM 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 -16h gap is not.
With a -16h gap there is no shared 9-to-5 window, so alternate the early start: one week Indonesia takes the early slot, the next week AKST does.

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 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).

Best time to call between Indonesia and AKST

With a -16h offset there is no overlap inside a normal 9 AM – 5 PM day. AKST opens at 9:00 AM AKST, which is 5:00 PM in Indonesia, so real-time calls need an early-morning or late-evening slot on one side.

Business hours overlap

Indonesia and AKST have no shared working hours because of the -16h gap. Teams need to alternate early starts or rely on asynchronous handovers.

Indonesia is 16 hours behind AKST (WIB UTC+07:00 → AKST UTC-09:00). There is no shared 9-to-5 window, so plan around an early or late slot. Remember to re-check around daylight-saving transitions.
