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).

Comparing Time Zones: PST and BRT

PST runs on Pacific Standard Time (PST) at UTC-08:00. BRT runs on Brasilia Time (BRT) at UTC-03:00. That puts PST 5 hours ahead of BRT — a difference of +5h at the current offsets.

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

Why people convert PST to BRT time

Scheduling a call from PST to BRT: a 10:00 AM start in PST lands at 3:00 PM in BRT, so you can confirm the slot without doing the arithmetic yourself.
Finding shared working hours: both PST and BRT are inside the 9-to-5 working day between 9:00 AM and 12:00 PM PST time (2:00 PM–5:00 PM BRT). That is roughly 3 hours of usable overlap.
Booking travel or deliveries: tracking BRT local time against PST keeps pickup windows and arrival estimates honest across the +5h offset.

Always state the zone abbreviation, not just the hour. "3:00 PM PST" is unambiguous; "3 PM" across a +5h gap is not.
Block 9:00 AM–12:00 PM PST as the recurring meeting window if you work primarily from PST and need BRT colleagues present.

About PST (Pacific Standard Time)

Pacific Standard Time (PST) covers the west coast of North America, including tech hubs like San Francisco and Seattle, and entertainment capital Los Angeles. The Pacific Time Zone is home to Silicon Valley and the world's largest technology companies. During summer, clocks advance to Pacific Daylight Time (PDT, UTC-07:00). PST is also observed in Baja California, Mexico.

About BRT (Brasilia Time)

Brasilia Time (BRT) is the standard time in the most populous regions of Brazil, including São Paulo, Rio de Janeiro, and the capital Brasília. Brazil abolished daylight saving time in 2019, so BRT is now observed year-round in these regions. Brazil spans four time zones in total.

Best time to call between PST and BRT

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

Business hours overlap

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

PST is 5 hours ahead of BRT (PST UTC-08:00 → BRT UTC-03:00). The shared working window is 9:00 AM–12:00 PM PST. Remember to re-check around daylight-saving transitions.
