Days of the Week in Spanish: ¡Aprende Rápido!
Learning the days of the week is one of the first essential steps in mastering Spanish. They are crucial for making plans, understanding schedules, and talking about daily life.
The great news is that, unlike in English, the days of the week in Spanish are not capitalized (unless they start a sentence). Also, most of the days are named after planets and Roman gods!
The Days of the Week
Here is the full list of the seven days, along with their pronunciation and a note on their origin:
| Day | Spanish Word | Pronunciation (IPA) | Origin |
| Monday | lunes | /ˈlu.nes/ | Moon’s Day ($Luna$) |
| Tuesday | martes | /ˈmaɾ.tes/ | Mars’ Day ($Marte$) |
| Wednesday | miércoles | /ˈmjeɾ.ko.les/ | Mercury’s Day ($Mercurio$) |
| Thursday | jueves | /ˈxwe.βes/ | Jupiter’s Day ($Júpiter$) |
| Friday | viernes | /ˈbjeɾ.nes/ | Venus’ Day ($Venus$) |
| Saturday | sábado | /ˈsa.βa.ðo/ | Sabbath/Saturn |
| Sunday | domingo | /doˈmiŋ.ɡo/ | Day of the Lord ($Dominus$) |
Key Rules to Remember
-
Capitalization: Remember, only capitalize the days of the week when they start a sentence.
-
Gender: All days of the week are masculine (el lunes, el martes, etc.).

-
lunes, martes, miércoles, jueves, viernes are the same in both singular and plural forms. You change the article to plural: el lunes (Monday) → los lunes (Mondays).
-
sábado → sábados
