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 Seoul time

Scheduling a call from Philippines to Seoul: a 10:00 AM start in Philippines lands at 11:00 AM in Seoul, so you can confirm the slot without doing the arithmetic yourself.
Finding shared working hours: both Philippines and Seoul are inside the 9-to-5 working day between 9:00 AM and 4:00 PM PHT time (10:00 AM–5:00 PM KST). That is roughly 7 hours of usable overlap.
Watching a live event or market open: Philippines viewers need 10:00 AM in Seoul to catch a 9:00 AM start there, and 11:00 PM if the event is anchored to Philippines.

Always state the zone abbreviation, not just the hour. "3:00 PM PHT" is unambiguous; "3 PM" across a +1h gap is not.
Block 9:00 AM–4:00 PM PHT as the recurring meeting window if you work primarily from Philippines and need Seoul colleagues present.

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 KST (Korea Standard Time)

Korea Standard Time (KST) is the time zone used in South Korea. It shares the same UTC offset as Japan Standard Time but is a distinct time zone. South Korea does not observe daylight saving time. Seoul, the capital, is a major global tech and business hub.
