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).

Key Facts about BDST

•Bangladesh uses a single time zone, UTC+06:00, across the entire country.
•Bangladesh does not observe daylight saving time, so the offset is fixed all year.
•Dhaka is one of the most densely populated cities globally.
•BDST is written here to distinguish it from British Summer Time (BST).

Key Facts about NPT

•Nepal Time is UTC+05:45 — a 45-minute offset, not a whole or half hour.
•The 45-minute offset was adopted in 1986 to match Kathmandu's solar time.
•Nepal does not observe daylight saving time.
•Nepal is 15 minutes ahead of India, despite sharing a long open border.

Comparing Time Zones: Bangladesh and Nepal

Bangladesh runs on Bangladesh Standard Time (BDST) at UTC+06:00. Nepal runs on Nepal Time (NPT) at UTC+05:45. That puts Bangladesh 15 minutes behind Nepal — a difference of -0h 15m at the current offsets.

In practice, when it is 9:00 AM in Bangladesh it is 8:45 AM in Nepal. Midnight in Bangladesh is 11:45 PM in Nepal. Neither zone observes daylight saving time, so the offset between them stays constant all year.

Why people convert Bangladesh to Nepal time

Scheduling a call from Bangladesh to Nepal: a 10:00 AM start in Bangladesh lands at 9:45 AM in Nepal, so you can confirm the slot without doing the arithmetic yourself.
Finding shared working hours: both Bangladesh and Nepal are inside the 9-to-5 working day between 9:15 AM and 5:00 PM BDST time (9:00 AM–4:45 PM NPT). That is roughly 7 hours 45 minutes of usable overlap.
Keeping family and friends in sync: knowing that 8:00 PM in Bangladesh is 7:45 PM in Nepal 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 -0h 15m gap is not.
Block 9:15 AM–5:00 PM BDST as the recurring meeting window if you work primarily from Bangladesh and need Nepal 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 NPT (Nepal Time)

Nepal Time (NPT) runs at UTC+05:45, one of only a handful of time zones worldwide that are not a whole or half hour from UTC. Nepal set its offset to 5 hours 45 minutes ahead of UTC in 1986 to mark the country's position between the 75°E and 90°E meridians; Kathmandu's solar time sits just over 5 hours 41 minutes ahead of Greenwich, so the 45-minute offset tracks the sun more closely than either 5:30 or 6:00 would. Nepal does not observe daylight saving time, so NPT is fixed all year. The offset makes Nepal 15 minutes ahead of India Standard Time (UTC+05:30) and 2 hours 15 minutes ahead of Dubai (UTC+04:00).

Best time to call between Bangladesh and Nepal

Both Bangladesh and Nepal sit inside the 9 AM – 5 PM working day between 9:15 AM–5:00 PM BDST, which is 9:00 AM–4:45 PM NPT. That gives roughly 7 hours and 45 minutes of shared time — the safest window for a live call or meeting.

Business hours overlap

Bangladesh and Nepal share 7 hours of working-hours overlap (9:15 AM–5:00 PM BDST), so scheduling a live meeting is straightforward.

Bangladesh is 15 minutes behind Nepal (BDST UTC+06:00 → NPT UTC+05:45). The shared working window is 9:15 AM–5:00 PM BDST. Remember to re-check around daylight-saving transitions.
