The user is asking for information about the change of time (likely daylight saving time) in different languages or contexts: “on change quand d heure” which translates roughly to “when do we change the time” in French, and the sequence of words suggests a request for when the clock changes, perhaps in France. Direct answer
- In France for 2025, the transition to winter time occurs in the night from Saturday to Sunday, October 25–26. At 3:00 a.m. local time, clocks are set back one hour to 2:00 a.m. This means you gain one hour of sleep on that night. [En France en 2025, le passage à l’heure d’hiver a lieu dans la nuit du samedi 25 au dimanche 26 octobre, à 3 heures du matin, il sera 2 heures.](javascript:void(0))
If you need the information for other countries or years, I can provide concise notes for each location (e.g., start/end dates, spring vs. autumn transitions) and include simple mnemonics to remember the direction of the change.
