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 +3h Gap: Helsinki vs BDST

Helsinki runs on Eastern European Summer Time (EEST) at UTC+03:00, currently observing daylight saving time. BDST runs on Bangladesh Standard Time (BDST) at UTC+06:00. That puts Helsinki 3 hours ahead of BDST — a difference of +3h at the current offsets.

In practice, when it is 9:00 AM in Helsinki it is 12:00 PM in BDST. Midnight in Helsinki is 3:00 AM in BDST.Helsinki observes daylight saving time while BDST does not, so the gap narrows or widens by an hour part of the year.

Why people convert Helsinki to BDST time

Scheduling a call from Helsinki to BDST: a 10:00 AM start in Helsinki lands at 1:00 PM in BDST, so you can confirm the slot without doing the arithmetic yourself.
Finding shared working hours: both Helsinki and BDST are inside the 9-to-5 working day between 9:00 AM and 2:00 PM EEST time (12:00 PM–5:00 PM BDST). That is roughly 5 hours of usable overlap.
Coordinating a Helsinki-based team with BDST contacts: quoting times in the other side's local clock — not your own — removes the single biggest source of missed meetings.

Always state the zone abbreviation, not just the hour. "3:00 PM EEST" is unambiguous; "3 PM" across a +3h gap is not.
Block 9:00 AM–2:00 PM EEST as the recurring meeting window if you work primarily from Helsinki and need BDST colleagues present.
Helsinki: Clocks fall back on Sun, Oct 25, 2026. Re-check this page after that date because the offset changes and so does the +3h gap.

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.

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.

Best time to call between Helsinki and BDST

Both Helsinki and BDST sit inside the 9 AM – 5 PM working day between 9:00 AM–2:00 PM EEST, which is 12:00 PM–5:00 PM BDST. That gives roughly 5 hours of shared time — the safest window for a live call or meeting.

Business hours overlap

Helsinki and BDST share 5 hours of working-hours overlap (9:00 AM–2:00 PM EEST), so scheduling a live meeting is straightforward.

Helsinki is 3 hours ahead of BDST (EEST UTC+03:00 → BDST UTC+06:00). The shared working window is 9:00 AM–2:00 PM EEST. Remember to re-check around daylight-saving transitions.
