Days of the Week in Spanish

The Spanish week starts on Monday, and the days are never capitalised. The article in front of the day decides whether you mean one Monday or every Monday.

On Monday, and every Monday

Spanish uses the article instead of a preposition. El lunes means on Monday, one specific Monday. There is no word for on.

Make it plural and it becomes a habit: los lunes means on Mondays, every Monday.

Only sábado and domingo add an s in the plural. The five weekdays already end in s and do not change, so el lunes and los lunes differ by one letter at the front.

Days are never capitalised in Spanish, even at the start of a date.

  • Nos vemos el viernes.See you on Friday.
  • Los domingos no trabajo.I don't work on Sundays.
