Telling time in France is just like telling time in the military. A
twenty-four hour clock is used for just about all scheduling. Trains,
buses, or airline schedules for example will, after 12:59, use this
format. For example, instead of 1:00 p.m. it would be 13:00. This is
also true of appointments, doctors or dentists and so on. If you are not
use to telling time this way, it can be confusing, especially if you are
being told a time in French - it's like you have to do two translations.
I have on more than one occasion misunderstood an appointment and not
been where I should be at the right time. Luckily, I usually
misunderstand in such a way that I am early. The way I figure out what
time it is: if someone tells me I have an appointment at 15:45, I drop
the 1 and take 2 off the 5. It works most times, probably the best
solution would be to buy a clock that tells military time. Below is
twenty-four hours in US and French time. The h stands for heure or hour.
