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).

Everything You Need to Know About GST and NZST Time

GST runs on Gulf Standard Time (GST) at UTC+04:00. NZST runs on New Zealand Standard Time (NZST) at UTC+12:00. That puts GST 8 hours ahead of NZST — a difference of +8h at the current offsets.

In practice, when it is 9:00 AM in GST it is 5:00 PM in NZST. Midnight in GST is 8:00 AM in NZST. Neither zone observes daylight saving time, so the offset between them stays constant all year.

Why people convert GST to NZST time

Scheduling a call from GST to NZST: a 10:00 AM start in GST lands at 6:00 PM in NZST, so you can confirm the slot without doing the arithmetic yourself.
Handling a +8h gap: GST and NZST 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 NZST is 5:00 PM in GST.
Watching a live event or market open: GST viewers need 5:00 PM in NZST to catch a 9:00 AM start there, and 4:00 PM if the event is anchored to GST.

Always state the zone abbreviation, not just the hour. "3:00 PM GST" is unambiguous; "3 PM" across a +8h gap is not.
With a +8h gap there is no shared 9-to-5 window, so alternate the early start: one week GST takes the early slot, the next week NZST does.

About GST (Gulf Standard Time)

Gulf Standard Time (GST) is the time zone used in the United Arab Emirates, Oman, and other Gulf states. GST does not observe daylight saving time. Dubai and Abu Dhabi, major international business and tourism hubs, operate on GST.

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).

Best time to call between GST and NZST

With a +8h offset there is no overlap inside a normal 9 AM – 5 PM day. NZST opens at 9:00 AM NZST, which is 5:00 PM in GST, so real-time calls need an early-morning or late-evening slot on one side.

Business hours overlap

GST and NZST have no shared working hours because of the +8h gap. Teams need to alternate early starts or rely on asynchronous handovers.

GST is 8 hours ahead of NZST (GST UTC+04:00 → NZST UTC+12:00). There is no shared 9-to-5 window, so plan around an early or late slot. Remember to re-check around daylight-saving transitions.
