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 Philippines to Honolulu time

Scheduling a call from Philippines to Honolulu: a 10:00 AM start in Philippines lands at 4:00 PM in Honolulu the previous day, so you can confirm the slot without doing the arithmetic yourself.
Handling a -18h gap: Philippines and Honolulu 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 Honolulu is 3:00 PM in Philippines.
Coordinating a Philippines-based team with Honolulu 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 -18h gap is not.
With a -18h gap there is no shared 9-to-5 window, so alternate the early start: one week Philippines takes the early slot, the next week Honolulu does.

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 HST (Hawaii Standard Time)

Hawaii Standard Time (HST) is used in the state of Hawaii and does not observe daylight saving time. This makes HST one of the most consistent time zones in the US. The Hawaiian Islands are among the last places on Earth to see a new calendar day.

Best time to call between Philippines and Honolulu

With a -18h offset there is no overlap inside a normal 9 AM – 5 PM day. Honolulu opens at 9:00 AM HST, which is 3:00 PM in Philippines, so real-time calls need an early-morning or late-evening slot on one side.

Business hours overlap

Philippines and Honolulu have no shared working hours because of the -18h gap. Teams need to alternate early starts or rely on asynchronous handovers.

Philippines is 18 hours behind Honolulu (PHT UTC+08:00 → HST UTC-10:00). There is no shared 9-to-5 window, so plan around an early or late slot. Remember to re-check around daylight-saving transitions.
