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 Indonesia to Ho Chi Minh time

Scheduling a call from Indonesia to Ho Chi Minh: a 10:00 AM start in Indonesia lands at 10:00 AM in Ho Chi Minh, so you can confirm the slot without doing the arithmetic yourself.
Finding shared working hours: both Indonesia and Ho Chi Minh are inside the 9-to-5 working day between 9:00 AM and 5:00 PM WIB time (9:00 AM–5:00 PM ICT). That is roughly 8 hours of usable overlap.
Watching a live event or market open: Indonesia viewers need 9:00 AM in Ho Chi Minh to catch a 9:00 AM start there, and 12:00 AM 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 +0h gap is not.
Block 9:00 AM–5:00 PM WIB as the recurring meeting window if you work primarily from Indonesia and need Ho Chi Minh colleagues present.
