There is a difference between (some regions of) France and Switzerland :
Switzerland :
In the morning we eat "le déjeûner".
In the midday we eat "le dîner".
In the evening we eat "le souper".
France :
In the morning they eat "le petit déjeûner".
In the midday they eat "le déjeûner".
In the evening they eat "le dîner".
Like :
In all french-speaking regions (Belgian, Quebecer, French, etc.), people say - for "eighty" - "quatre-vingt", except in Switzerland... where we say "huitante".
(Switzerland / out-of-Switzerland)
seventy : septante / soixante-dix
seventy-one : septante et un / soixante et onze
...
eighty : huitante / quatre-vingt
eighty-one : huitante et un / quatre vingt un
...
ninety : nonante / quatre-vingt dix
ninety-one : nontante et un / quatre vingt onze
...

We - Swiss - often say that "Les Français ne parlent pas français." (French people don't speak french. For example : they say "soixante-dix" but they say "la guerre de septante".)
