French: Cinq à sept (in French sɛ̃k a sɛt/, literally 'five to seven') is a French-language term for activities taking place after work and before returning home (sometimes using overtime as an excuse), or having dinner (roughly between 5 and 7 p.m.). It may also be written as French: 5 à 7 or 5@7.
In Quebec French, the term stands for a social gathering. It may bring together friends or colleagues or may be organized around a specific event, such as a book launch or vernissage. Wine, beer, and cocktails are served along with finger foods and other hors d'oeuvres. Such a party held later may be named for the specific time (e.g. French: six à huit, meaning "six to eight").
A French: cinq à sept can be a formal gathering held in a wide range of public and private spaces, such as art galleries, university campuses, and places of work, but it is also commonly used more informally as a promotion in bars to attract patrons.[1] The English equivalent might be a semi-formal "wine and cheese" gathering or an informal "happy hour".
French: Cinq à sept originally referred to a time for a tryst, and consequently is a metonym for a visit to one's mistress, an extramarital affair, and the mistress involved. It derived from the time of day French people would make such a visit. It is still commonly considered as the time of day to meet one's mistress or lover, and the term implies a sexual liaison (as opposed to the Québécois habit).
