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: JST and MYT

JST runs on Japan Standard Time (JST) at UTC+09:00. MYT runs on Malaysia Time (MYT) at UTC+08:00. That puts JST 1 hour behind MYT — a difference of -1h at the current offsets.

In practice, when it is 9:00 AM in JST it is 8:00 AM in MYT. Midnight in JST is 11:00 PM in MYT. Neither zone observes daylight saving time, so the offset between them stays constant all year.

Why people convert JST to MYT time

Scheduling a call from JST to MYT: a 10:00 AM start in JST lands at 9:00 AM in MYT, so you can confirm the slot without doing the arithmetic yourself.
Finding shared working hours: both JST and MYT are inside the 9-to-5 working day between 10:00 AM and 5:00 PM JST time (9:00 AM–4:00 PM MYT). That is roughly 7 hours of usable overlap.
Booking travel or deliveries: tracking MYT local time against JST keeps pickup windows and arrival estimates honest across the -1h offset.

Always state the zone abbreviation, not just the hour. "3:00 PM JST" is unambiguous; "3 PM" across a -1h gap is not.
Block 10:00 AM–5:00 PM JST as the recurring meeting window if you work primarily from JST and need MYT colleagues present.

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.

About MYT (Malaysia Time)

Best time to call between JST and MYT

Both JST and MYT sit inside the 9 AM – 5 PM working day between 10:00 AM–5:00 PM JST, which is 9:00 AM–4:00 PM MYT. That gives roughly 7 hours of shared time — the safest window for a live call or meeting.

Business hours overlap

JST and MYT share 7 hours of working-hours overlap (10:00 AM–5:00 PM JST), so scheduling a live meeting is straightforward.

JST is 1 hour behind MYT (JST UTC+09:00 → MYT UTC+08:00). The shared working window is 10:00 AM–5:00 PM JST. Remember to re-check around daylight-saving transitions.
