What is the time difference between KST and HKT?

Hong Kong Time (HKT) is 1 hour behind Korea Standard Time (KST). KST uses a UTC offset of UTC+9, while HKT uses UTC+8. For example, when it's 9:00 AM in KST, it's 8:00 AM in HKT. This difference remains constant year-round since neither timezone observes daylight saving time. Use the conversion table above to see the exact time for each hour of the day.

How do I convert KST to HKT?

To convert KST to HKT, subtract 1 hour from the KST time. For example, 9:00 AM KST is 8:00 AM HKT, and 5:00 PM KST is 4:00 PM HKT. Since neither timezone observes DST, this conversion stays the same all year. You can also use the interactive converter above for quick, accurate results.

What time is it in HKT when it's noon in KST?

When it's 12:00 PM (noon) in KST, it's 11:00 AM in HKT. This is because HKT is 1 hour behind KST. Similarly, when it's 6:00 PM in KST, it's 5:00 PM in HKT. This relationship is constant throughout the year. The color-coded conversion table above shows every hour mapped between both timezones.

How many hours behind is HKT from KST?

HKT is 1 hour behind KST. This means when it's 9:00 AM in KST, it's 8:00 AM in HKT, and when it's midnight in KST, it's 11:00 PM in HKT. This offset is constant throughout the year since neither timezone uses daylight saving time. The conversion table above provides a complete hour-by-hour mapping.

Is HKT ahead or behind KST?

HKT is behind KST by 1 hour. Clocks in HKT show an earlier time than KST, meaning the day starts later in HKT relative to KST. For example, when it's noon in KST, it's still 11:00 AM in HKT. This difference stays the same year-round.
