Time difference and jet lag: practical tips
In clock terms, going from the UK or the US East Coast to Indonesia means travelling east: your day is shortened and you will need to go to bed earlier than usual. A few simple rules help you adjust to local time:
- Set your watch and phone to local time as soon as you board.
- Align meals and bedtime with local time from the first day.
- Plan a light first day, with no important meetings or long drives.
- Get out in daylight when you arrive and avoid long naps.
- If you take medication at fixed times, ask your doctor how to adapt the schedule to the time difference.

Jet lag: how flight direction affects you in Indonesia
- Outbound from the UK or the US (flying east): you « lose » 7 hours from London in UK winter and 6 hours in summer, and 12 hours from New York in winter and 11 hours in summer; your arrival day is shortened and you need to go to bed earlier than your body clock expects.
- Return to the UK or the US (flying west): the opposite applies. Flying west is generally considered easier to cope with: you just need to stay up a little later.
- Your usual night at home (23:00 – 07:00) corresponds to 06:00 – 14:00 in Jakarta, Java, Sumatra (WIB) from London in UK winter (05:00 – 13:00 during BST), and to 11:00 – 19:00 from New York during EST (10:00 – 18:00 during EDT): this is when your body will want to sleep for the first few days.
- Daylight on arrival: in Jakarta, the sun rises around 05:49 and sets around 18:15 in mid-January, and around 06:05 and 17:52 in mid-July (table above). After flying east, seek morning light and avoid it late in the day; this is the standard advice for shifting your body clock.
