Frequently Asked Questions
What is the time difference between HKT and MDT?
During standard time, Mountain Daylight Time is 14 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.
When does MDT start and end?
MDT begins on the second Sunday in March at 02:00 local MST time, when clocks spring forward one hour from MST (UTC-7) to MDT (UTC-6). It ends on the first Sunday in November at 02:00 local MDT time, when clocks fall back to MST. In 2026, MDT runs from March 8 through November 1, covering the majority of the calendar year.
Is Arizona on MDT?
Most of Arizona — including Phoenix and Tucson — does not observe Daylight Saving Time and remains on MST (UTC-7) year-round under a state law in effect since 1968, meaning Arizona does not advance to MDT each March. The significant exception is the Navajo Nation, a sovereign territory spanning parts of northeastern Arizona, southeastern Utah, and northwestern New Mexico, which does observe DST and shifts to MDT on the standard federal schedule.
