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 AKST time

Scheduling a call from São Paulo to AKST: a 10:00 AM start in São Paulo lands at 4:00 AM in AKST, so you can confirm the slot without doing the arithmetic yourself.
Finding shared working hours: both São Paulo and AKST are inside the 9-to-5 working day between 3:00 PM and 5:00 PM BRT time (9:00 AM–11:00 AM AKST). That is roughly 2 hours of usable overlap.
Booking travel or deliveries: tracking AKST local time against São Paulo keeps pickup windows and arrival estimates honest across the -6h offset.

Always state the zone abbreviation, not just the hour. "3:00 PM BRT" is unambiguous; "3 PM" across a -6h gap is not.
Block 3:00 PM–5:00 PM BRT as the recurring meeting window if you work primarily from São Paulo and need AKST colleagues present.

About BRT (Brasilia Time)

About AKST (Alaska Standard Time)

Alaska Standard Time (AKST) is used in nearly all of Alaska. Due to Alaska's vast geographic size, the Aleutian Islands use Hawaii-Aleutian Standard Time instead. During summer months, Alaska switches to Alaska Daylight Time (AKDT, UTC-08:00).

Both São Paulo and AKST sit inside the 9 AM – 5 PM working day between 3:00 PM–5:00 PM BRT, which is 9:00 AM–11:00 AM AKST. That gives roughly 2 hours of shared time — the safest window for a live call or meeting.

Business hours overlap

São Paulo and AKST overlap for about 2 hours during the working day — enough for meetings if you avoid the edges of the window.
