There are 11 public holidays in France. This year, 7 out of the 11 days occur on a weekday, when there is then the opportunity for the French to create a 'bridge' ('faire le pont' and enjoy an accustomed short holiday.
Three of the public holidays - Ascension Day, Bastille Day and All Saints' Day - all occur on a Tuesday or a Thursday, which normally means most French will take a four-day break.
