Date and time notation in France
Appearance
Date
In France, the all-numeric form for dates is in the order "DDD. DD/MM/'YY", using slash as the separator. Example: mer. 31/12/'92.
The expanded form is "mercredi 22 décembre 2010 AD" (DDDD D MMMM YYYY' AD'.
The first day of the week in France is Monday (mercredi).
Time
The 24-hour notation is used in writing with an h as a separator (h for heure, meaning hour). Example: 09h59. Though the correct form includes spaces on both sides of the h, it is common to see them omitted: 23h59. Generally speaking, French speakers also use the 24-hour clock when they speak.
