What Is the 5 to 7 Rule in French?
Le cinq à sept literally means five to seven, and it refers to the window between finishing work and getting home. What people are assumed to be doing in that window depends entirely on which side of the Atlantic you are standing on.
In France, the phrase traditionally refers to a discreet meeting with a lover. In Quebec, it means after work drinks.
It is not a rule of French grammar, despite how the question tends to get typed into Google. It is a cultural expression, and it is one of the clearest examples of how the same French can mean opposite things in different places.
What does cinq à sept mean in France?
In French usage, un cinq à sept has long carried the sense of an extramarital affair. Larousse lists it as an invariable masculine noun in exactly this sense.
The logic behind it is practical and slightly bleak. The hours between leaving the office and arriving home are unaccounted for. Nobody expects you anywhere. So they became the traditional slot for a rendezvous.
The phrase is old. Time magazine was writing about the French cinq à sept as a recognised institution back in 1966, and Françoise Sagan used it in her fiction the following year. It belongs to a particular era and, by most accounts, a particular social class.
It is not vulgar and it is not quite slang. It is knowing. A French speaker who says it about someone is making an implication, not noting a time in a diary.
What does cinq à sept mean in Quebec?
Something completely different, and completely respectable.
In Quebec French, un 5 à 7 is happy hour. Colleagues going for a drink after work, a networking evening, a gallery opening with wine and canapés. Wiktionnaire records both senses side by side, with the Quebec meaning covering formal events like a vernissage as well as informal drinks between friends.
You will see it written as 5 à 7 or 5@7 on posters and invitations. It appears in bar promotions. It is entirely ordinary.
If the gathering starts later, the name simply shifts. A six à huit is the same idea, two hours later.
The hours are identical to the French version. The assumption about what happens in them is not.
How do I use it without embarrassing myself?
Match the country you are in.
In Montreal, inviting a colleague to un 5 à 7 is friendly and unremarkable. Not inviting them might be the bigger social error.
In Paris, saying the same thing to a colleague will land very differently, and you will find out how differently within about two seconds.
If you are unsure, use the neutral alternatives, which work everywhere:
- Prendre un verre après le travail, to have a drink after work. Completely safe, no second meaning
- L'apéro, the everyday French term for early evening drinks. Universal and slightly warmer
- Un pot, informal, often used for a drinks gathering marking an occasion at work
Why do phrases like this split between countries?
Quebec French and French French separated a few centuries ago and have been developing in different directions ever since.
Sometimes Quebec preserves an older meaning that France abandoned. Sometimes each side invents something new for the same words. Sometimes England and the United States happen to be involved, since Quebec sits in an English speaking continent and France does not.
Other splits worth knowing before they catch you out:
- Gosses. Kids in France. Testicles in Quebec. This one causes genuine problems and it comes up more often than you would think
- Blonde. A hair colour in France. Your girlfriend in Quebec
- Chum. Meaningless in France. Your boyfriend, or a male friend, in Quebec
- Dîner. Dinner in France. Lunch in Quebec, where the evening meal is souper
- Char. A tank or a chariot in France. Your car in Quebec
None of these are errors. They are two healthy versions of the same language, and knowing which one you are speaking is part of speaking it well.
Does anyone still use it in the French sense?
Hard to say, which is itself interesting.
The phrase is universally recognised in France among older speakers. Whether the practice it describes was ever as widespread as its reputation suggests is a different question, and one nobody is well placed to answer honestly.
Younger French speakers know the expression but are noticeably less likely to use it, and some of the very youngest do not know it at all. It reads as belonging to a previous generation, in the same way certain English euphemisms do.
The Quebec sense, meanwhile, is thriving and entirely current.
Why this matters beyond one phrase
The useful lesson here is not about cinq à sept specifically. It is that vocabulary carries culture, and translation alone will not warn you.
A dictionary can tell you that cinq à sept means five to seven. It cannot tell you that using it in the wrong country will make a colleague uncomfortable. That information lives in the context around the word, not in the word itself.
This is the strongest practical argument for learning vocabulary in sentences rather than in pairs, and for paying attention to which variety of French you are learning. A word list will happily hand you a phrase that is perfectly correct and completely wrong for the room.
