- Place 'when' immediately after a time noun like 'day', 'year', or 'moment'. Example: 'The year when we met.'
- The clause following 'when' must contain a subject and a verb. Example: '...when the sun sets.'
- In informal English, 'when' can often be replaced by 'that' or omitted entirely. Example: 'The day (that) we left.'

Common Mistakes
which o that en lugar de when sin una preposición.- The Preposition Trap: Los estudiantes a menudo dicen, 'The day
whichI met her.' (¡Incorrecto!) Necesitaswhenuon which. Si usaswhich, debes tener la preposición: 'The dayon whichI met her.' Perowhenes mucho más natural. - Double Time: Evita decir 'The time
whenit happenedthen.' No necesitasthenal final de la cláusula porquewhenya hizo el trabajo. Es como usar dos pares de gafas de sol: redundante y un poco raro. - Confusing with 'Where': Asegúrate de que tu sustantivo sea realmente un tiempo. A veces la gente dice 'The place
whenI was born.' A menos que hayas nacido dentro de un reloj gigante, probablemente querías decir 'The placewhereI was born.' - Forgetting the Noun:
Whennecesita un 'sustantivo de tiempo' al cual referirse en estas cláusulas relativas. Si dices 'I rememberwhenwe met,' esa es una estructura ligeramente diferente (una cláusula sustantiva). Para una cláusula relativa, necesitas el sustantivo: 'I remember thetimewhenwe met.'

Delete the preposition immediately. 'When' does all the work by itself.

Preguntas frecuentes (8)
Yes, in informal English, `that` is very common, especially after 'day' or 'time'. Example: 'The day `that` we met.'
Yes, if the time noun is the object of the main clause. 'I remember the day (when) we met.' This is very common in spoken English.
`In which` is much more formal. You would use it in an academic essay, whereas `when` is used in daily conversation.
Absolutely. You can say 'The very second `when` the bomb exploded.' It works for any duration of time.
Because `when` already acts as the prepositional phrase 'on which'. Adding 'on' again is like saying the same thing twice.
As a relative adverb, yes. If there is no noun, it is likely a subordinating conjunction or a question word.
No, `where` is strictly for locations. However, some languages (like French) use the same word for both, which causes confusion.
It is not redundant; it is grammatically standard. While you can say 'I remember when...', adding 'the time' makes it a relative clause.
