Jet lag from Sydney to Los Angeles
Flying from Sydney to Los Angeles is 5 to 7 hours east on the clock, depending on the date. Jetlag Away moves your body clock earlier, the harder direction, starting in the nights before you fly.
You land in Los Angeles on an earlier calendar date than you left Sydney, which feels like going back in time. For the body clock it is an eastbound trip: the shift is made by moving it earlier, which is the harder direction, and arriving in the morning means the first hours of local daylight need care.
The shift through 2027
The difference between the two clocks changes when either country changes its clocks, so the same flight is not the same trip all year. This is the shift for a departure at 10:00 Sydney time, measured at each end at the moment you are there, the way the app measures it.
| Departing | Shift | What the plan does |
|---|---|---|
| 1 January – 13 March | 5 hours east | Moves your clock earlier |
| 14 March – 3 April | 6 hours east | Moves your clock earlier |
| 4 April – 2 October | 7 hours east | Moves your clock earlier |
| 3 October – 6 November | 6 hours east | Moves your clock earlier |
| 7 November – 31 December | 5 hours east | Moves your clock earlier |
How long it takes
The plan moves your sleep a little each night before you fly, then sets light, sleep and caffeine on local time until the shift is made. How much it does before departure, and how many days after landing carry light instructions, depend on the intensity you choose. These are the app's figures with its default limits: never woken before 05:00, never kept up after 01:30. They are a schedule, not a promise of how you will feel.

Leaving Sydney at 10:00 on 3 July 2027 and landing in Los Angeles at 06:30 on 3 July, local time. 7 hours east, so the plan moves your clock earlier. Built at the moderate intensity for someone who usually sleeps 23:30 to 07:00.
