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 -10h Gap: NZST vs SAST

NZST runs on New Zealand Standard Time (NZST) at UTC+12:00. SAST runs on South Africa Standard Time (SAST) at UTC+02:00. That puts NZST 10 hours behind SAST — a difference of -10h at the current offsets.

In practice, when it is 9:00 AM in NZST it is 11:00 PM in SAST on the previous day. Midnight in NZST is 2:00 PM in SAST. Neither zone observes daylight saving time, so the offset between them stays constant all year.

Why people convert NZST to SAST time

Scheduling a call from NZST to SAST: a 10:00 AM start in NZST lands at 12:00 AM in SAST, so you can confirm the slot without doing the arithmetic yourself.
Handling a -10h gap: NZST and SAST 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 SAST is 11:00 PM in NZST.
Watching a live event or market open: NZST viewers need 11:00 PM in SAST to catch a 9:00 AM start there, and 10:00 AM if the event is anchored to NZST.

Always state the zone abbreviation, not just the hour. "3:00 PM NZST" is unambiguous; "3 PM" across a -10h gap is not.
With a -10h gap there is no shared 9-to-5 window, so alternate the early start: one week NZST takes the early slot, the next week SAST does.

About NZST (New Zealand Standard Time)

New Zealand Standard Time (NZST) is the standard time zone for New Zealand and its dependencies. New Zealand is among the first countries to see a new calendar day. During summer (September to April), clocks advance to New Zealand Daylight Time (NZDT, UTC+13:00).

About SAST (South Africa Standard Time)

South Africa Standard Time (SAST) is used in South Africa, Lesotho, and Eswatini. SAST does not observe daylight saving time. Johannesburg and Cape Town are major economic hubs in Africa.

Best time to call between NZST and SAST

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

Business hours overlap

NZST and SAST have no shared working hours because of the -10h gap. Teams need to alternate early starts or rely on asynchronous handovers.

NZST is 10 hours behind SAST (NZST UTC+12:00 → SAST UTC+02:00). There is no shared 9-to-5 window, so plan around an early or late slot. Remember to re-check around daylight-saving transitions.
