Temporal conjunctions in Spanish with cuando mientras antes de que despues de que and hasta que
Temporal conjunctions connect actions in time: cuando, mientras, antes de que, después de que, hasta que.

Why temporal conjunctions matter

Temporal conjunctions are essential for telling stories, giving instructions, describing routines and talking about future plans. They show whether one action happens before, after, during or until another action. They also introduce one of the most important grammar decisions in Spanish: indicative or subjunctive after time expressions.

How to use this page

Use this page after learning basic sentence structure and before studying more advanced subordinate clauses. First learn the meaning of each conjunction. Then focus on the verb mood: factual or repeated actions normally use the indicative, while future or not-yet-real actions often use the subjunctive.

Facts and routines

Use the indicative when the action is real, repeated or factual.

Cuando llego a casa, descanso.
When I get home, I rest.

Future actions

Use the subjunctive when the action is expected but not yet completed.

Cuando llegue a casa, descansaré.
When I get home, I will rest.

Same subject

With the same subject, Spanish often uses antes de or después de + infinitive.

Antes de salir, llamo a Ana.
Before leaving, I call Ana.

Main temporal conjunctions in Spanish

Temporal conjunctions can express when something happens, how long it lasts, what happens before or after it, and what event must happen first.

Spanish conjunction English meaning Example Use
cuando when Te llamo cuando llego. Connects an action with a time or event.
mientras while Escucho música mientras estudio. Two actions happen at the same time.
antes de que before Llámame antes de que salgas. One action happens before another.
después de que after Descansamos después de que llegamos. One action happens after another.
hasta que until Espero hasta que terminas. Action continues until another action happens.
en cuanto as soon as Te escribo en cuanto llego. One action follows immediately after another.
tan pronto como as soon as Salimos tan pronto como termina la clase. Immediate time sequence.
desde que since Vivo aquí desde que llegué. Starting point in time.
Memory line: temporal conjunctions answer time questions: when, while, before, after, until, since and as soon as.

Indicative or subjunctive after temporal conjunctions

The most important grammar point is not the conjunction itself, but the verb that follows it. Use the indicative for real, factual, habitual or past actions. Use the subjunctive when the action is future, expected, planned or not yet completed.

Meaning Indicative Subjunctive Difference
When Cuando tengo tiempo, leo. Cuando tenga tiempo, leeré. Habit now vs future condition.
After Después de que llegó, cenamos. Después de que llegue, cenaremos. Past fact vs expected future event.
Until Espero hasta que termina. Esperaré hasta que termine. Known repeated event vs future event.
As soon as Te llamo en cuanto llego. Te llamaré en cuanto llegue. Routine vs future action.

Cuando: when

Cuando means “when”. It can take the indicative or the subjunctive depending on whether the event is factual, habitual or future.

Spanish English meaning Verb mood Reason
Cuando estudio, escucho música. When I study, I listen to music. Indicative Habit or repeated action.
Cuando estudié en Madrid, vivía cerca del centro. When I studied in Madrid, I lived near the centre. Indicative Past fact.
Cuando estudie mañana, apagaré el teléfono. When I study tomorrow, I will turn off the phone. Subjunctive Future event not yet completed.

Mientras: while

Mientras means “while” and connects two simultaneous actions. It often appears with the present, imperfect or another tense that describes an ongoing action.

Spanish English meaning Use
Escucho música mientras cocino. I listen to music while I cook. Two habitual or present actions.
Leía mientras mi hermano estudiaba. I was reading while my brother was studying. Two ongoing past actions.
Mientras esperas, puedes leer. While you wait, you can read. Action during another action.

Be careful with mientras que. It can also mean “whereas” in contrastive sentences: Yo prefiero café, mientras que Ana prefiere té.

Antes de que and después de que

Antes de que means “before” and usually introduces a subordinate clause with the subjunctive. Después de que can take the indicative for factual events and the subjunctive for future or not-yet-completed events.

Conjunction Spanish example English meaning Grammar point
antes de que Llámame antes de que salgas. Call me before you leave. Subjunctive after antes de que.
antes de + infinitive Antes de salir, cierro la puerta. Before leaving, I close the door. Same subject: use infinitive.
después de que Después de que llegó, cenamos. After he/she arrived, we had dinner. Indicative for past fact.
después de que Después de que llegue, cenaremos. After he/she arrives, we will have dinner. Subjunctive for future event.
después de + infinitive Después de comer, salimos. After eating, we go out. Same subject or general action.

Hasta que, en cuanto and tan pronto como

These conjunctions are common when one action depends on another. The same indicative/subjunctive logic applies: factual or habitual action takes indicative; future action takes subjunctive.

Conjunction Indicative example Subjunctive example Meaning
hasta que Espero hasta que termina. Esperaré hasta que termine. until
en cuanto Te llamo en cuanto llego. Te llamaré en cuanto llegue. as soon as
tan pronto como Salimos tan pronto como termina la clase. Saldremos tan pronto como termine la clase. as soon as
apenas Apenas llega, empieza a trabajar. Apenas llegue, empezará a trabajar. as soon as / just as

Other useful temporal expressions

Some temporal expressions are especially useful for stories, routines and more precise time relationships.

Expression English meaning Example Note
desde que since Vivo aquí desde que llegué. Starting point in time.
cada vez que every time that Cada vez que viajo, aprendo algo. Repeated event.
siempre que whenever / provided that Siempre que puedo, leo en español. Can be temporal or conditional.
una vez que once Una vez que termine, te aviso. Often future + subjunctive.
al + infinitive upon / when Al llegar, vi a Ana. Compact alternative to a time clause.

Word order and commas

Temporal clauses can come before or after the main clause. When the temporal clause comes first, a comma is often helpful in writing.

Order Spanish example English meaning
Main clause first Te llamo cuando llego. I call you when I arrive.
Temporal clause first Cuando llego, te llamo. When I arrive, I call you.
Future temporal clause first Cuando llegue, te llamaré. When I arrive, I will call you.
Infinitive phrase first Antes de salir, cierro la puerta. Before leaving, I close the door.

Typical mistakes with Spanish temporal conjunctions

  • Using the future after cuando in future time clauses: say cuando llegue, not cuando llegará.
  • Forgetting the subjunctive after antes de que: say antes de que salgas.
  • Using que with the same subject unnecessarily: say antes de salir, not usually antes de que salgo.
  • Confusing mientras and mientras que: mientras often means “while”; mientras que can mean “whereas”.
  • Translating English word order too directly: Spanish often uses subjunctive where English uses a present form for future time: when I arrive = cuando llegue.
  • Forgetting mood changes with the same conjunction: cuando llego and cuando llegue are both correct, but they mean different things.

FAQ: temporal conjunctions in Spanish

What are temporal conjunctions in Spanish?

Temporal conjunctions are words or phrases that connect actions in time. Examples include cuando, mientras, antes de que, después de que, hasta que and en cuanto.

What does cuando mean in Spanish?

Cuando means “when”. It can take the indicative for facts and routines or the subjunctive for future events that have not happened yet.

Do temporal conjunctions need the subjunctive?

They need the subjunctive when the action is future, expected or not yet completed. They take the indicative when the action is factual, habitual or already completed.

Why is it cuando llegue and not cuando llegará?

In Spanish, future time clauses after cuando normally use the subjunctive, not the future tense: cuando llegue means “when I arrive”.

What is the difference between antes de and antes de que?

Antes de is followed by an infinitive when the subject is the same: antes de salir. Antes de que introduces a clause with a conjugated verb, usually in the subjunctive: antes de que salgas.

What is the difference between mientras and mientras que?

Mientras usually means “while” in a time sense. Mientras que can also mean “whereas” when it contrasts two ideas.
