Avoid These Mistakes When Using Lunes
Capitalizing days of the week
Incorrect: Tengo clase el Lunes.
Correct: Tengo clase el lunes.
Spanish writes days of the week in lowercase, unlike English. Lunes, martes, miércoles, never capitalized except at the start of a sentence.
Adding a preposition like en or on
Incorrect: En lunes tengo cita.
Correct: El lunes tengo cita.
Spanish uses the article el (or los for habitual) without a preposition. Adding en or a is a common English transfer error.
