Time difference between London and Mexico City

Right nowLoading current times…

Mexico City is 6 hours behind London at the start of the year; the gap changes 2 times during 2026 because the two cities change their clocks on different dates. London uses Europe/London (UTC+0 standard); Mexico City uses America/Mexico City (UTC−6 standard). The live line above shows the gap at this moment.

How this is calculated

difference = offset(America/Mexico_City, t) − offset(Europe/London, t), evaluated at each instant t — it is not a constant when the two cities change clocks on different dates

The difference is the gap between the two cities’ UTC offsets at a given instant, taken from the IANA time zone database via the Intl API. It is recomputed live for the current moment, and for the year’s schedule below it is evaluated across every clock change in either city — which is why some pairs have several values a year and others one.

The overlap grid uses September 3, 2026 and 9-to-5 working hours; open the meeting planner for any other date or hours.
