The other day, I heard the loveliest phase – “Month of May, gruyère month”, or as the lovely woman shared with me, “mai gruyère”. This refers to the fact that in France (and much of Europe), the month of May is packed with public holidays, turning the calendar into a block of Swiss cheese—well, Gruyère, to be precise. And the gruyère cheese – if you can imagine it – is full of holes. So, May has many public holidays, just like the holes in gruyère cheese.
