San Luis Potosí does not change its clocks
A fixed offset, all year round
San Luis Potosí stays on Central Standard Time at UTC-06:00 every day of the year. There is no spring-forward or fall-back here, which puts it with the majority: most of the world's time zones do not observe daylight saving.
That sounds like it makes scheduling simpler, and locally it does — but it introduces a different trap for anyone working with San Luis Potosí from a country that does change clocks. The offset between you and San Luis Potosí is not constant: it changes when your clocks move, even though nothing changed here. A recurring call that has run at the same local time for months will shift by an hour, from your side, without anyone editing the invite.
When the gap to San Luis Potosí changes
Dates in the next year where the difference shifts, by counterpart city
The difference between two cities is not a constant. It changes whenever either side moves its clocks — and because regions switch on different dates, there are short windows each year when the usual gap is wrong. These are the dates that matter for San Luis Potosí:
London (United Kingdom)
- From 25 October 2026: San Luis Potosí is 6 hours behind London
- From 28 March 2027: San Luis Potosí is 7 hours behind London
Frankfurt (Germany)

- From 28 March 2027: San Luis Potosí is 8 hours behind Frankfurt
Tokyo (Japan)
Neither San Luis Potosí nor Tokyo changes its clocks in the next year, so the gap between them stays fixed. One less thing to track.
