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 +5h Gap: Nigeria vs Dhaka

Nigeria runs on West Africa Time (WAT) at UTC+01:00. Dhaka runs on Bangladesh Standard Time (BDST) at UTC+06:00. That puts Nigeria 5 hours ahead of Dhaka — a difference of +5h at the current offsets.

In practice, when it is 9:00 AM in Nigeria it is 2:00 PM in Dhaka. Midnight in Nigeria is 5:00 AM in Dhaka. Neither zone observes daylight saving time, so the offset between them stays constant all year.

Why people convert Nigeria to Dhaka time

Scheduling a call from Nigeria to Dhaka: a 10:00 AM start in Nigeria lands at 3:00 PM in Dhaka, so you can confirm the slot without doing the arithmetic yourself.
Finding shared working hours: both Nigeria and Dhaka are inside the 9-to-5 working day between 9:00 AM and 12:00 PM WAT time (2:00 PM–5:00 PM BDST). That is roughly 3 hours of usable overlap.
Coordinating a Nigeria-based team with Dhaka 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 WAT" is unambiguous; "3 PM" across a +5h gap is not.
Block 9:00 AM–12:00 PM WAT as the recurring meeting window if you work primarily from Nigeria and need Dhaka colleagues present.

About WAT (West Africa Time)

West Africa Time (WAT) is used across much of West and Central Africa, including Nigeria, the most populous country in Africa. WAT does not observe daylight saving time and shares the same offset as Central European Time (CET).

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 Nigeria and Dhaka

Both Nigeria and Dhaka sit inside the 9 AM – 5 PM working day between 9:00 AM–12:00 PM WAT, which is 2:00 PM–5:00 PM BDST. That gives roughly 3 hours of shared time — the safest window for a live call or meeting.

Business hours overlap

Nigeria and Dhaka overlap for about 3 hours during the working day — enough for meetings if you avoid the edges of the window.

Nigeria is 5 hours ahead of Dhaka (WAT UTC+01:00 → BDST UTC+06:00). The shared working window is 9:00 AM–12:00 PM WAT. Remember to re-check around daylight-saving transitions.
