Frequently Asked Questions

What is the time difference between HKT and GMT?

During standard time, Greenwich Mean Time is 8 hours behind Hong Kong Time.

Does Hong Kong observe Daylight Saving Time?

Hong Kong does not observe Daylight Saving Time and has not done so since 1979, remaining permanently fixed at UTC+8:00 throughout the year. This means the offset between Hong Kong and any DST-observing country shifts by one hour twice annually when those countries change their clocks — but HKT itself never moves.

Are HKT and SGT the same time?

Yes, Hong Kong Time (HKT) and Singapore Time (SGT) share the identical UTC+8:00 offset, and neither territory observes Daylight Saving Time, making the two cities permanently synchronized on the same clock year-round. The same alignment holds with mainland China (CST), Taiwan, Malaysia (MYT), and Western Australia (AWST) — placing Hong Kong and Singapore at the heart of the world's largest permanent UTC+8 economic bloc.

What is the difference between GMT and BST?

GMT (Greenwich Mean Time) is the UK's standard winter offset at UTC+0, observed from the last Sunday in October through the last Sunday in March. BST (British Summer Time) is the daylight saving offset at UTC+1, applied each summer when clocks advance one hour.

Is GMT the same as UTC?

GMT and UTC share exactly the same numerical offset — both represent UTC+00:00 — but they are fundamentally different in nature. UTC is an atomic-clock-based international time standard used as the global reference, while GMT is a geographic time zone legally observed by specific countries including the United Kingdom and Ireland during winter months.
