When to call Mexico from the UK or the US
To reach someone between 09:00 and 20:00 Mexico City time, call between 15:00 and 02:00 (running past midnight) London time in UK winter, and between 16:00 and 03:00 (running past midnight) during British Summer Time. From New York, call between 10:00 and 21:00 during EST, and between 11:00 and 22:00 during EDT.
With such a large gap, working days barely overlap: 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
Flying to Mexico from Europe means travelling west: your day is lengthened and you will need to stay up later than usual. From the US, the gap is small (Mexico City is 1 hour behind New York in winter and 2 hours behind New York in summer), so jet lag mostly affects travellers from the UK, Europe or Asia. 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 Mexico
- Outbound from the UK (flying west): you « gain » 6 hours in UK winter and 7 hours in summer; your arrival day is lengthened and tiredness hits early in the local evening.
- Return to the UK (flying east): the opposite applies. Flying east shortens the day: plan a quiet day when you get home.
- Your usual night at home (23:00 – 07:00) corresponds to 17:00 – 01:00 in Mexico City from London in UK winter (16:00 – 00:00 during BST), and to 22:00 – 06:00 in Mexico City from New York during EST (21:00 – 05:00 during EDT): this is when your body will want to sleep for the first few days.
- Daylight on arrival: in Mexico City, the sun rises around 07:13 and sets around 18:18 in mid-January, and around 06:07 and 19:18 in mid-July (table above). After flying west, make the most of late-afternoon light to stay up until the evening; this is the standard advice for shifting your body clock.
