jour vs journée (and matin/matinée, soir/soirée, an/année)
Summary
French has two words for each unit of time: the short masculine form (jour, matin, soir, an) names the unit as a countable point, while the feminine -ée form (journée, matinée, soirée, année) names the whole span as it is filled and experienced.
Explanation
French offers a pair of words for the same stretch of time: jour / matin / soir / an on one side, and journée / matinée / soirée / année on the other. English has only one word for each ("day", "morning", "evening", "year"), so learners must actively choose. The short masculine forms name the unit as a discrete, countable point or slot; the feminine -ée forms name the same period seen as a duration, a container you fill with activity or that has a quality.
Use the short form (jour, an…) when you count units or locate a point: trois jours (three days), deux ans (two years), un jour sur deux (every other day), le premier jour (the first day). It is also the form in fixed greetings and calendar labels: Bonjour, le jour de Noël, ce matin, ce soir, tous les ans. Think of it as the number-and-calendar word.
Use the -ée form when you look at the whole span as it unfolds, especially with toute (all) or with an adjective describing how it went: toute la journée (all day long), une belle soirée (a lovely evening), une année difficile (a difficult year), passer la matinée à lire (to spend the morning reading). This is why you wish someone Bonne journée / Bonne soirée: you are wishing them a good span of time to live through, not merely marking the calendar slot.
Two contrasts make the split vivid. Greeting vs. wish: Bonjour is the fixed hello, but Bonne journée sends someone off into their whole day. Counting vs. describing time: l'année dernière (last year) and il y a deux ans (two years ago) — the -ée form appears when année is felt as a lived stretch or carries an adjective (dernière), while the bare count after a number takes an (deux ans).
Watch the traps for English speakers. Because English collapses the pair, learners often reach for the -ée form everywhere (*trois journées for "three days") or the short form everywhere (*bon jour ! for a farewell). Note also the gender flip: jour, matin, soir, an are masculine (un beau jour), but journée, matinée, soirée, année are feminine (une belle journée) — the adjective must agree accordingly.
Rule of thumb: if you are counting units or pointing at a calendar slot, use the short masculine form (jour, matin, soir, an); if you mean the filled, experienced span — often with toute or a descriptive adjective — use the feminine -ée form (journée, matinée, soirée, année). "How many?" → short form; "what was it like / all of it?" → -ée form.
Examples
J'ai travaillé toute la journée. — I worked all day long. (The filled, experienced span -> journée, reinforced by toute.)
Je reviens dans trois jours. — I'll be back in three days. (Counting units after a number -> the short form jour.)
Bonjour ! — Merci, bonne journée ! — Hello! — Thanks, have a good day! (Fixed greeting Bonjour vs. the wish Bonne journée (a whole span to live).)
Nous avons passé une très belle soirée. — We had a very lovely evening. (An adjective describing how the span went -> soirée.)
L'année dernière, il y a eu beaucoup de neige. — Last year there was a lot of snow. (année carries the adjective dernière; contrast with the bare count il y a deux ans.)
Le train part tous les matins à huit heures. — The train leaves every morning at eight. (A recurring calendar point -> the short form matin.)
Common mistakes
J'ai travaillé tout le jour.
J'ai travaillé toute la journée.
to describe the whole span of a day filled with an activity, especially with tout(e), French uses the feminine -ée form journée, not the short counting form jour; note also the agreement toute la (feminine), not tout le.
