La Conversion

AM/PM → 24h : 1h-11h AM = 01:00-11:00. 12 PM (midi) = 12:00. 1h-11h PM = 13:00-23:00. 12 AM (minuit) = 00:00. En France, le format 24h est le standard au quotidien — le format AM/PM est une spécificité anglo-saxonne.

Astuce

Après midi : soustrayez 12 pour obtenir l'heure PM. 15:00 - 12 = 3 PM. Avant midi : ajoutez « du matin ». Le format 24h élimine toute ambiguïté — impossible de confondre 8h du matin et 8h du soir.

⚡ CalcWolf Insight

The most common military time mistake: saying "fourteen hundred hours" when you mean 1400. In military parlance, it is "fourteen hundred" (no "hours"). Adding "hours" at the end is technically civilian speech, though widely accepted outside formal military contexts.

Frequently asked questions
Comment convertir 15:00 ?
15 - 12 = 3 PM.
Et minuit ?
Minuit = 00:00 en format 24h. 12:00 = midi. Ne confondez pas 12 AM (minuit) et 12 PM (midi) — c'est l'erreur la plus courante.
