What is bonne fete translated in English?

Answer 1

In Canada and other non-France French speaking areas, bonne fete is usually translated as happy birthday, although the locals will also understand you if you say "Joyeaux Anniversaire" or "Bon Anniversaire".

However, in France, bonne fete is usually written on a card to celebrate someone's feast day of their Patron Saint. This is a little abstract, but it works like this:

If you're name is Rachel, for example, then you refer to the Saint Calendar and you find that Saint Rachel's birthday was on the 15 January. You therefore celebrate your fete on the 15 January. (Note: Bonne only means happy, or good.)
