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).

Understanding the +1h Gap: Bangladesh vs Bangkok

Bangladesh runs on Bangladesh Standard Time (BDST) at UTC+06:00. Bangkok runs on Indochina Time (ICT) at UTC+07:00. That puts Bangladesh 1 hour ahead of Bangkok — a difference of +1h at the current offsets.

In practice, when it is 9:00 AM in Bangladesh it is 10:00 AM in Bangkok. Midnight in Bangladesh is 1:00 AM in Bangkok. Neither zone observes daylight saving time, so the offset between them stays constant all year.

Why people convert Bangladesh to Bangkok time

Scheduling a call from Bangladesh to Bangkok: a 10:00 AM start in Bangladesh lands at 11:00 AM in Bangkok, so you can confirm the slot without doing the arithmetic yourself.
Finding shared working hours: both Bangladesh and Bangkok are inside the 9-to-5 working day between 9:00 AM and 4:00 PM BDST time (10:00 AM–5:00 PM ICT). That is roughly 7 hours of usable overlap.
Keeping family and friends in sync: knowing that 8:00 PM in Bangladesh is 9:00 PM in Bangkok makes it easy to avoid calling at 3 AM.

Always state the zone abbreviation, not just the hour. "3:00 PM BDST" is unambiguous; "3 PM" across a +1h gap is not.
Block 9:00 AM–4:00 PM BDST as the recurring meeting window if you work primarily from Bangladesh and need Bangkok colleagues present.

About BDST (Bangladesh Standard Time)

Bangladesh Standard Time (BDST) is the single time zone used across Bangladesh, fixed at UTC+06:00 all year. Bangladesh has not observed daylight saving time since a short-lived experiment in 2009, so the gap between Bangladesh and every other zone is constant. Dhaka, the capital, is one of the most densely populated cities in the world. Because the country sits close to the middle of the UTC+06:00 band, solar noon is near 12:00 for most of the year. BDST is listed separately from British Summer Time, which shares the BST abbreviation but is UTC+01:00.

About ICT (Indochina Time)

Indochina Time (ICT) is used across Southeast Asia including Vietnam, Thailand, Laos, and Cambodia. Indonesia (Western time, WIB) also uses UTC+07:00. ICT does not observe daylight saving time.

Best time to call between Bangladesh and Bangkok

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

Business hours overlap

Bangladesh and Bangkok share 7 hours of working-hours overlap (9:00 AM–4:00 PM BDST), so scheduling a live meeting is straightforward.

Bangladesh is 1 hour ahead of Bangkok (BDST UTC+06:00 → ICT UTC+07:00). The shared working window is 9:00 AM–4:00 PM BDST. Remember to re-check around daylight-saving transitions.
