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).

Jakarta to EDT Time Difference – Complete Guide

Jakarta runs on Western Indonesia Time (WIB) at UTC+07:00. EDT runs on Eastern Daylight Time (EDT) at UTC-04:00. That puts Jakarta 11 hours behind EDT — a difference of -11h at the current offsets.

In practice, when it is 9:00 AM in Jakarta it is 10:00 PM in EDT on the previous day. Midnight in Jakarta is 1:00 PM in EDT. Neither zone observes daylight saving time, so the offset between them stays constant all year.

Why people convert Jakarta to EDT time

Scheduling a call from Jakarta to EDT: a 10:00 AM start in Jakarta lands at 11:00 PM in EDT the previous day, so you can confirm the slot without doing the arithmetic yourself.
Handling a -11h gap: Jakarta and EDT 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 EDT is 10:00 PM in Jakarta.
Booking travel or deliveries: tracking EDT local time against Jakarta keeps pickup windows and arrival estimates honest across the -11h offset.

Always state the zone abbreviation, not just the hour. "3:00 PM WIB" is unambiguous; "3 PM" across a -11h gap is not.
With a -11h gap there is no shared 9-to-5 window, so alternate the early start: one week Jakarta takes the early slot, the next week EDT 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 EDT (Eastern Daylight Time)

Eastern Daylight Time (EDT) is used during the summer months (second Sunday of March to the first Sunday of November) in the Eastern Time Zone. During EDT, clocks are advanced by one hour to take advantage of longer daylight hours. Not all locations in the Eastern Time Zone observe DST – Panama, Jamaica, and most of the Caribbean remain on EST year-round.

Best time to call between Jakarta and EDT

With a -11h offset there is no overlap inside a normal 9 AM – 5 PM day. EDT opens at 9:00 AM EDT, which is 10:00 PM in Jakarta, so real-time calls need an early-morning or late-evening slot on one side.

Business hours overlap

Jakarta and EDT have no shared working hours because of the -11h gap. Teams need to alternate early starts or rely on asynchronous handovers.

Jakarta is 11 hours behind EDT (WIB UTC+07:00 → EDT UTC-04:00). There is no shared 9-to-5 window, so plan around an early or late slot. Remember to re-check around daylight-saving transitions.
