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 NZDT to São Paulo time

Scheduling a call from NZDT to São Paulo: a 10:00 AM start in NZDT lands at 6:00 PM in São Paulo the previous day, so you can confirm the slot without doing the arithmetic yourself.
Handling a -16h gap: NZDT and São Paulo 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 São Paulo is 5:00 PM in NZDT.
Coordinating a NZDT-based team with São Paulo contacts: quoting times in the other side's local clock — not your own — removes the single biggest source of missed meetings.

Always state the zone abbreviation, not just the hour. "3:00 PM NZDT" is unambiguous; "3 PM" across a -16h gap is not.
With a -16h gap there is no shared 9-to-5 window, so alternate the early start: one week NZDT takes the early slot, the next week São Paulo does.

About NZDT (New Zealand Daylight Time)

New Zealand Daylight Time (NZDT) is the summer time zone for New Zealand, one hour ahead of New Zealand Standard Time (NZST, UTC+12:00). It runs from the last Sunday in September to the first Sunday in April, so New Zealand shifts a week or two earlier in spring than Australia. At UTC+13:00, NZDT is among the earliest offsets in the world — only Samoa, Tonga and parts of Kiribati run further ahead at certain times of year. Auckland and Wellington are 13 hours ahead of UTC during NZDT, 12 hours ahead of Sydney, and 18 hours ahead of New York. The Chatham Islands, 45 minutes further east, move to UTC+13:45.

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.
