Time expressions for past and future — French time travel (without the flux capacitor)

You already know how to say Im going to do something (futur proche) and I will do something (futur simple). Now let's give those verbs a calendar, a clock, and maybe an existential crisis about when exactly things happen.

Why this matters (quick, dramatic whisper)

If verbs are the engine, time expressions are the GPS. They tell listeners whether you mean yesterday, tomorrow, in two hours, or sometime during next summer when you finally decide to learn conjugations. Using the wrong expression ruins plans, confuses people, and makes your life story sound like a weird mashup of past and future.

This builds on your work with futur proche and futur simple: use those forms, but add the right time expression to be specific and natural.

Big categories at a glance

• Past markers: show that something already happened. Example words: hier, la semaine dernière, il y a, autrefois.
• Future markers: show that something will happen. Example words: demain, dans X, la semaine prochaine, d'ici.
• Duration and continuity: pendant, depuis, pour, en. These tell you how long or whether an action keeps going.

Common past time expressions (with when to use them)

• hier — yesterday
  • Hier, je suis allé au marché. (Yesterday I went to the market.)
• avant-hier — the day before yesterday
• la semaine dernière / le mois dernier / l'année dernière — last week / last month / last year
• il y a + duration — X ago
  • Il y a deux jours, j'ai rencontré Sophie. (Two days ago I met Sophie.)
• autrefois / autrefois / jadis — formerly, used for older stories or habits

Notes:

• Use these frequently with passé composé for completed actions: J'ai vu ce film hier.
• If you are giving background or descriptions in the past, pair with imparfait: Quand j'étais petit, je jouais dehors tous les jours.

Common future time expressions (and subtle differences)

• demain — tomorrow
  • Demain, je vais partir. (Tomorrow I am going to leave.)
• après-demain — the day after tomorrow
• la semaine prochaine / le mois prochain / l'année prochaine — next week / next month / next year
• dans + duration — in X time from now (count forward)
  • Je pars dans deux jours. (I leave in two days.)
• d'ici + duration — by/in at most (deadline sense)
  • D'ici vendredi, j'aurai terminé. (By Friday I will have finished.)
• à + day/time — see you/at (à demain, à lundi)
• ce + period — ce soir, ce week-end, ce matin (useful with futur proche)

Tip: Use futur proche for near future actions with ce soir / demain / dans une heure. Use futur simple for more remote or formal future references, or to sound a little more certain/official.

Duration words that trip learners up (and how to use them)

Quick memory trick:

• pendant = "for the whole sandwich"
• depuis = "start point to now"
• dans = "countdown"
• en = "how long it takes"

Positioning: where do time expressions go in the sentence?

• Time expressions are flexible. Common placements:
  • Beginning for emphasis: Hier, j'ai pris le bus.
  • End for a casual note: J'ai pris le bus hier.
  • Before infinitive with negatives/auxiliary: Je vais partir demain. Je ne vais pas partir demain.

Note on agreement: next/last with nouns agrees in gender/number. Example: la semaine prochaine, le mois dernier.

Everyday conversation examples (practical + a tiny bit dramatic)

Dialogue: making plans, uses both past and future markers

• A: Salut! Tu vas bien? Qu'est-ce que tu as fait hier soir?
  B: J'ai dîné avec Claire hier soir. Et toi?
  A: J'ai regardé la série que tu m'as recommandée. Demain, on se voit pour un café?
  B: Oui, je suis libre demain après-midi. On se retrouve à 15h?
  A: Parfait. À demain!

Notes:

• Hier (past), demain (future), demain après-midi (more precise future). Futur proche would be natural: Je vais te voir demain.

Practice: fill in the blanks

1. Je pars ___ deux jours. (in two days)
2. ___, j'ai rencontré mon prof. (two days ago)
3. J'etudie le français ___ 2018. (since)
4. Nous avons parlé ___ une heure. (for/length)
5. Il viendra ___ vendredi. (by/at the latest)

Answers: 1. dans 2. Il y a deux jours 3. depuis 2018 4. pendant 5. d'ici vendredi

Common learner mistakes (so you dont look like a time traveller who lost the manual)

• Using pendant when you mean depuis: Je l'attends depuis deux heures (Ive been waiting for two hours — still waiting). Saying pendant here could imply you waited then stopped.
• Mixing up dans and en: Je finis le travail en deux heures (it will take me two hours). Je finis dans deux heures (I finish two hours from now).
• Using dernier instead of prochain or vice versa: la semaine dernière = last week; la semaine prochaine = next week.

Little pro tip: When you say something like Je pars pour deux semaines, French often uses pour for planned durations. It sounds natural — not a mistake.

Wrap-up — the one-liner you should tattoo on your brain

• Use hier, la semaine dernière, il y a for the past; demain, dans X, la semaine prochaine, d'ici for the future.
• Use pendant for completed durations, depuis for ongoing durations, en for how long something takes, and dans for when something will start.

Practice by telling a friend a short story: one past event and one plan for the future, and pepper it with a duration and a deadline. If they understand you, congrats — you just time-traveled fluently.

Version: now go make confusingly accurate plans in French. Or at least sound like you know what day it is.
