Time difference and jet lag: practical tips
In clock terms, going from the UK or the US East Coast to India 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 India
- Outbound from the UK or the US (flying east): you « lose » 5 hours 30 minutes from London in UK winter and 4 hours 30 minutes in summer, and 10 hours 30 minutes from New York in winter and 9 hours 30 minutes 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 04:30 – 12:30 in New Delhi, Mumbai from London in UK winter (03:30 – 11:30 during BST), and to 09:30 – 17:30 from New York during EST (08:30 – 16:30 during EDT): this is when your body will want to sleep for the first few days.
- Daylight on arrival: in New Delhi, the sun rises around 07:15 and sets around 17:46 in mid-January, and around 05:33 and 19:21 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.
