When to use lower case letters in Spanish

We have seen the main uses of the capital letters in Spanish. Now you may wonder, what about the days of the week? Or the months of the year? Aren’t they on this list? Exactly, they are not, because they are not capitalized in Spanish, unlike English.

So now we are going to see in which cases you must not use the capital letter in Spanish.


Days of the week. Do not use capital letters in the days of the weeks in Spanish. Use lower case: lunes, martes, miércoles, jueves, viernes, sábado y domingo.

Months of the year in Spanish are also in lower case: enero, febrero, marzo, abril, mayo, junio, julio, agosto, septiembre, octubre, noviembre y diciembre.

❌ And seasons with lower case too… primavera, verano, otoño e invierno.

The cardinal points: norte, sur, este y oeste. And also their combinations: noroeste, sureste and so on.

Religions also in lower case, e.g. Ella es musulmana y él es budista.
