Best Meeting Time: London to Mexico City
🕐 Live Timezone Overlap: London & Mexico City
London and Mexico City sit 7 hours apart, which makes scheduling a live call genuinely difficult. Mexico City is behind, so when London's working day (9am–6pm) opens, Mexico City is still in the small hours. The two cities share only 2 hours of mutual working time each day: 4pm–6pm in London and 9am–11am in Mexico City. That narrow window demands careful planning, particularly on Fridays, when London offices often wind down by 4pm.
Time Difference: London and Mexico City
Mexico City is currently 7 hours behind London. The live offsets are London UTC+1 and Mexico City UTC-6. London observes daylight saving and Mexico City does not, so the offset shifts twice a year if both sides aren't already aligned.
London currently runs at UTC+1, having moved to British Summer Time. Mexico City stays at UTC−6 all year: Mexico discontinued daylight saving in most of the country in 2022 and no longer observes it. That means the gap shifts twice a year. When London reverts to UTC+0 in autumn, the difference between London and Mexico City widens from 7 hours to 8 hours. The changeover happens in late October, so check the date before booking calls that month.
Best Times to Meet
The 2-hour overlap runs 4pm–6pm in London and 9am–11am in Mexico City. Inside that 2-hour window, 4pm–5pm London time is generally the cleaner slot. London's cultural notes flag that informal meetings between 5pm and 6pm are common in finance, so a 4pm London start respects both cities' rhythms. In Mexico City, mornings before the long business lunch (which often runs 2pm–4pm local time) tend to be receptive for formal calls, making the 9am–10am Mexico City slot particularly suitable.

Tips for Scheduling Across London and Mexico City
- Book calls at 4pm London time: it catches Mexico City at 9am, before their long business lunch begins.
- When London reverts to UTC+0 in late October, the gap widens to 8 hours, cutting the overlap further.
- Avoid scheduling Mexico City calls on or around 16 September (Independence Day) and 1–2 November (Day of the Dead).
- London offices often clear out by 4pm on Fridays, so Friday calls risk a distracted or absent UK participant.
- Mexico City aligns with Chicago's Central Time, so a call that works for Chicago will also suit Mexico City.
Public Holidays and Working Weeks
Both London and Mexico City follow a standard Monday-to-Friday working week, 9am–6pm. Meetings should account for public holidays in both countries. London's next notable holidays are the May Bank Holiday and Christmas Day (25 December). Mexico City observes Independence Day on 16 September and Day of the Dead on 2 November. Clustering deadlines or recurring calls around those dates risks low attendance, so build both calendars into any standing meeting series.
