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 -11h Gap: Singapore vs Brazil

Singapore runs on Singapore Standard Time (SGT) at UTC+08:00. Brazil runs on Brasilia Standard Time (BRT) at UTC-03:00. That puts Singapore 11 hours behind Brazil — a difference of -11h at the current offsets.

In practice, when it is 9:00 AM in Singapore it is 10:00 PM in Brazil on the previous day. Midnight in Singapore is 1:00 PM in Brazil. Neither zone observes daylight saving time, so the offset between them stays constant all year.

Why people convert Singapore to Brazil time

Scheduling a call from Singapore to Brazil: a 10:00 AM start in Singapore lands at 11:00 PM in Brazil the previous day, so you can confirm the slot without doing the arithmetic yourself.
Handling a -11h gap: Singapore and Brazil have no overlap inside a normal 9-to-5 day, so real-time meetings need an early-morning or late-evening slot on one side. 9:00 AM in Brazil is 10:00 PM in Singapore.
Watching a live event or market open: Singapore viewers need 10:00 PM in Brazil to catch a 9:00 AM start there, and 11:00 AM if the event is anchored to Singapore.

Always state the zone abbreviation, not just the hour. "3:00 PM SGT" is unambiguous; "3 PM" across a -11h gap is not.
With a -11h gap there is no shared 9-to-5 window, so alternate the early start: one week Singapore takes the early slot, the next week Brazil does.

About SGT (Singapore Standard Time)

About BRT (Brasilia Time)

Best time to call between Singapore and Brazil

With a -11h offset there is no overlap inside a normal 9 AM – 5 PM day. Brazil opens at 9:00 AM BRT, which is 10:00 PM in Singapore, so real-time calls need an early-morning or late-evening slot on one side.

Business hours overlap

Singapore and Brazil have no shared working hours because of the -11h gap. Teams need to alternate early starts or rely on asynchronous handovers.

Singapore is 11 hours behind Brazil (SGT UTC+08:00 → BRT UTC-03:00). There is no shared 9-to-5 window, so plan around an early or late slot. Remember to re-check around daylight-saving transitions.
