HKG-bound flights are the slower direction by about 30 minutes in our estimate: the route runs partly east–west through latitudes where the prevailing westerly winds at cruise height are strong, so heading east rides a tailwind and heading west fights a headwind. How we estimate it.

Time zones and jet lag

YYZAmerica/Toronto — UTC−4 now; UTC−5 standard time, UTC−4 during daylight saving time
HKGAsia/Hong_Kong — UTC+8 now; UTC+8 all year (no daylight saving time)
DifferenceHong Kong is 12 hours ahead of Toronto today; +13 h in January and +12 h in July because daylight saving time starts and ends on different dates (or not at all).

Jet lag, flying YYZ → HKG. A 12-hour shift turns day into night: the body clock is as far out as it can be, and it makes little difference which way it adjusts. A common rule of thumb is that it adjusts by roughly one time zone a day, so expect up to a week or more to feel fully normal. Flying the other way, the shift is reversed.
