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 São Paulo to NST time

Scheduling a call from São Paulo to NST: a 10:00 AM start in São Paulo lands at 9:30 AM in NST, so you can confirm the slot without doing the arithmetic yourself.
Finding shared working hours: both São Paulo and NST are inside the 9-to-5 working day between 9:30 AM and 5:00 PM BRT time (9:00 AM–4:30 PM NST). That is roughly 7 hours 30 minutes of usable overlap.
Keeping family and friends in sync: knowing that 8:00 PM in São Paulo is 7:30 PM in NST makes it easy to avoid calling at 3 AM.

Always state the zone abbreviation, not just the hour. "3:00 PM BRT" is unambiguous; "3 PM" across a -0h 30m gap is not.
Block 9:30 AM–5:00 PM BRT as the recurring meeting window if you work primarily from São Paulo and need NST colleagues present.

About BRT (Brasilia Time)

About NST (Newfoundland Standard Time)

Newfoundland Standard Time (NST) is one of the few half-hour offset time zones in the world. It covers the island of Newfoundland in Canada and is 30 minutes ahead of Atlantic Standard Time. This unique offset exists because Newfoundland was an independent country until 1949.
