✕Common Mistakes
Me acuesto en las 10 de la noche.
The preposition *en* means ‘at’ for exact times, not ‘around’. Use *sobre* or *alrededor de* for approximations.
Me acuesto sobre 10 de la noche.
When using *sobre*, you still need the article *las* before the hour.
Me duermo sobre las 10 de la noche.
While *dormir* means ‘to sleep’, the reflexive form *acostarse* is the natural verb for ‘to go to bed’. Saying *Me duermo sobre…* sounds unnatural.

Cultural Tip
In many Spanish‑speaking countries people still refer to the time of day with *de la mañana*, *de la tarde* and *de la noche* rather than using ‘a.m.’/‘p.m.’. Using *sobre* for an approximate hour is common in casual conversation, but in formal contexts you might prefer *alrededor de* or simply state the exact hour.
