When the difference changes
Atlantic Time and Hong Kong Time do not change their clocks on the same dates, so the gap between them is not the same all year. Most converters show only today’s figure. These are the periods ahead:
- Now – March 14, 2027Hong Kong Time is 12 hours ahead
- March 14, 2027 – November 7, 2027Hong Kong Time is 11 hours ahead
- November 7, 2027 – onwardsHong Kong Time is 12 hours ahead
Periods shorter than a day are not listed. Each zone changes at its own local time, so on a date when both move there are a few hours when the gap is briefly something else.
Daylight saving
Atlantic Time
Clocks go forward one hour — 2:00 am becomes 3:00 am local time, and the zone is on ADT after that.
Hong Kong Time
Hong Kong Time stays on HKT all year, so its offset from UTC never moves.

Scheduling between the two
There is no overlap between a nine-to-six working day in Halifax and one in Hong Kong — the gap is too wide. A call has to sit early or late for one side. Early morning in Halifax is the usual compromise, since that is late afternoon or evening in Hong Kong.
A note on AST: it can also mean Arabia Standard Time (UTC+3). This page means Atlantic Time.
Atlantic Time (AST) is used in Nova Scotia, New Brunswick and Puerto Rico
