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 PHT to Santiago time

Scheduling a call from PHT to Santiago: a 10:00 AM start in PHT lands at 11:00 PM in Santiago the previous day, so you can confirm the slot without doing the arithmetic yourself.
Handling a -11h gap: PHT and Santiago 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 Santiago is 10:00 PM in PHT.
Coordinating a PHT-based team with Santiago 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 PHT" 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 PHT takes the early slot, the next week Santiago does.
Santiago: Clocks fall back on Sun, Apr 4, 2027. Any meeting series spanning that date will shift by an hour in local time.

About PHT (Philippine Time)

Philippine Time (PHT) is fixed at UTC+08:00 all year. The Philippines has not observed daylight saving time since 1978, apart from a brief trial in 1990. PHT shares its offset with China Standard Time, Hong Kong Time, Singapore Time, Malaysian Time and Australian Western Standard Time, which makes Manila a convenient bridge for scheduling across East and Southeast Asia. As one of the world's largest centres for business process outsourcing, Manila keeps overlapping hours with both Australia and, on early shifts, the United States, and its contact-centre schedules are usually planned around Manila local time.

About CLT (Chile Standard Time)

Chile Standard Time (CLT) is the standard time in Chile. During summer months (October to March), Chile switches to Chile Summer Time (CLST, UTC-03:00). Chile is the longest north-south country in the world.
