On 15 January 2027, office hours (09:00–17:00) overlap for 5 hours with London and for 0 hours with New York. Aim for the very start or end of the day, and always state the time zone in your meeting invitations.
Time difference and jet lag: practical tips
With a gap of at most 3 hours from London, the trip does not disrupt your rhythm much; the main trap is forgetting to set your watch or calendar to local time for a booked train, tour or meeting. From North America the gap is larger (+8 hours from New York in winter), so 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 Turkey
- Outbound from the UK (flying east): you « lose » 3 hours in UK winter and 2 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 (flying west): the opposite applies. Flying west is generally considered easier to cope with: you just need to stay up a little later.
- From New York (flying east): you « lose » 8 hours in winter (EST) and 7 hours in summer (EDT); your arrival day is shortened and you need to go to bed earlier than your body clock expects.
- Your usual night at home (23:00 – 07:00) corresponds to 02:00 – 10:00 in Istanbul from London in UK winter (01:00 – 09:00 during BST), and to 07:00 – 15:00 in Istanbul from New York during EST (06:00 – 14:00 during EDT): this is when your body will want to sleep for the first few days.
- Daylight on arrival: in Ankara, the sun rises around 08:08 and sets around 17:47 in mid-January, and around 05:32 and 20:17 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.
