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).

Comparing Time Zones: Jakarta and Romania

Jakarta runs on Western Indonesia Time (WIB) at UTC+07:00. Romania runs on Eastern European Summer Time (EEST) at UTC+03:00, also currently on daylight saving time. That puts Jakarta 4 hours behind Romania — a difference of -4h at the current offsets.

In practice, when it is 9:00 AM in Jakarta it is 5:00 AM in Romania. Midnight in Jakarta is 8:00 PM in Romania.Romania observes daylight saving time while Jakarta does not, so the gap narrows or widens by an hour part of the year.

Why people convert Jakarta to Romania time

Scheduling a call from Jakarta to Romania: a 10:00 AM start in Jakarta lands at 6:00 AM in Romania, so you can confirm the slot without doing the arithmetic yourself.
Finding shared working hours: both Jakarta and Romania are inside the 9-to-5 working day between 1:00 PM and 5:00 PM WIB time (9:00 AM–1:00 PM EEST). That is roughly 4 hours of usable overlap.
Keeping family and friends in sync: knowing that 8:00 PM in Jakarta is 4:00 PM in Romania makes it easy to avoid calling at 3 AM.

Always state the zone abbreviation, not just the hour. "3:00 PM WIB" is unambiguous; "3 PM" across a -4h gap is not.
Block 1:00 PM–5:00 PM WIB as the recurring meeting window if you work primarily from Jakarta and need Romania colleagues present.
Romania: Clocks fall back on Sun, Oct 25, 2026. Any meeting series spanning that date will shift by an hour in local time.

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 EET (Eastern European Time)

Eastern European Time (EET) covers a wide geographical area including Eastern Europe (Finland, Greece, Romania, Bulgaria, Ukraine), the Middle East (Israel, Lebanon, Jordan), and northeastern Africa (Egypt, Libya). During summer, most EET countries switch to Eastern European Summer Time (EEST, UTC+03:00). Turkey permanently moved to UTC+03:00 in 2016, effectively leaving EET.

Best time to call between Jakarta and Romania

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

Business hours overlap

Jakarta and Romania overlap for about 4 hours during the working day — enough for meetings if you avoid the edges of the window.

Jakarta is 4 hours behind Romania (WIB UTC+07:00 → EEST UTC+03:00). The shared working window is 1:00 PM–5:00 PM WIB. Remember to re-check around daylight-saving transitions.
