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 Santiago to HKT time

Scheduling a call from Santiago to HKT: a 10:00 AM start in Santiago lands at 9:00 PM in HKT, so you can confirm the slot without doing the arithmetic yourself.
Handling a +11h gap: Santiago and HKT 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 HKT is 8:00 PM in Santiago.
Watching a live event or market open: Santiago viewers need 8:00 PM in HKT to catch a 9:00 AM start there, and 1:00 PM if the event is anchored to Santiago.

Always state the zone abbreviation, not just the hour. "3:00 PM CLST" is unambiguous; "3 PM" across a +11h gap is not.
With a +11h gap there is no shared 9-to-5 window, so alternate the early start: one week Santiago takes the early slot, the next week HKT does.
Santiago: Clocks fall back on Sun, Apr 4, 2027. Re-check this page after that date because the offset changes and so does the +11h gap.

As a major financial centre, Hong Kong's trading hours set the rhythm for markets across Asia, opening at 09:30 HKT which is 01:30 in London and 20:30 the previous evening in New York.

Best time to call between Santiago and HKT

With a +11h offset there is no overlap inside a normal 9 AM – 5 PM day. HKT opens at 9:00 AM HKT, which is 8:00 PM in Santiago, so real-time calls need an early-morning or late-evening slot on one side.

Business hours overlap

Santiago and HKT have no shared working hours because of the +11h gap. Teams need to alternate early starts or rely on asynchronous handovers.

Santiago is 11 hours ahead of HKT (CLST UTC-03:00 → HKT UTC+08:00). There is no shared 9-to-5 window, so plan around an early or late slot. Remember to re-check around daylight-saving transitions.
