Names of the Days of the Week in Spanish

In Spanish, the week consists of seven days. Many names came from Latin and preserved their ancient origin.
In Spanish, the days of the week are written with a lowercase letter. For many students this seems unusual because in some languages such words are written with a capital letter.
For example:
  • Hoy es martes.
  • El viernes tengo clases.
Trabajo los lunes.
How the Days of the Week Are Used
Days of the week in Spanish are often used together with the article:
  • el lunes;
  • el jueves;
  • los domingos.
When talking about a regular action, the plural form is usually used.
For example:
  • Estudio los martes.
  • Trabajamos los viernes.
At the same time, lunes, martes, miércoles, jueves and viernes do not change in the plural.
Abbreviated Forms
In schedules, calendars, and apps, shortened forms can be found.
Such forms are often used:
  • in class schedules;
  • in electronic calendars;
  • in tickets;
in work schedules.
During conversations, native speakers regularly use simple constructions.
For example:
  • ¿Qué día es hoy?
  • ¿Qué haces el sábado?
  • ¿Trabajas los lunes?
Such phrases help people get used to the topic faster and begin using new words in everyday speech.
Questions with Days of the Week

Origin of the Names

Many Spanish days of the week appeared back in Ancient Rome. Their names are connected with planets, deities, and religious traditions.
  • Lunes
The word lunes is connected with the Moon. In Latin, the expression Lunae dies was used, which meant “day of the Moon.”

  • Martes
The name martes is connected with Mars, the god of war. That is why the word resembles the name of the planet Mars.

  • Miércoles
Miércoles comes from the name Mercury. In ancient Roman tradition, this day was dedicated specifically to him.

  • Jueves
Jueves is connected with Jupiter. The Latin form contained the name of the supreme god of Roman mythology.

  • Viernes
The name viernes is connected with Venus, the goddess of love and beauty.

  • Sábado
The word sábado has a different origin. It is connected with the Hebrew Sabbath.

  • Domingo
Domingo comes from the Latin word Dominicus. The meaning is connected with the “day of the Lord.”
Why the Origin Helps Memorization
When a student understands where the days of the week came from, the words begin to be memorized much faster. This especially helps people who find it difficult to learn vocabulary from lists.
For example:
  • martes → Mars;
  • viernes → Venus;
  • miércoles → Mercury.
Such associations help people navigate conversational speech faster.

How to Quickly Learn and Memorize the Names of the Days of the Week in Spanish

Many people try to learn the days of the week in one evening, but after a few days the words start getting mixed up. Regular repetition and using vocabulary in real life work much better.

  • Use the Days of the Week Every Day
The most effective way is to start regularly using the new words.
For example:
  • Hoy es lunes.
  • Mañana es martes.
  • El viernes descanso.
Even short phrases help people get used to new constructions faster.

  • Connect the Days of the Week with Habits
Memorization becomes easier if the words are connected with specific events.
For example:
  • lunes — beginning of the working week;
  • viernes — end of work;
  • domingo — rest.
This way the brain creates associations faster.

  • Repeat the Words Out Loud
Spanish pronunciation plays an important role. Simply reading is not enough.
It is useful to:
  • pronounce the days of the week;
  • listen to audio;
  • repeat phrases;
  • read the calendar in Spanish.
After some time the words start being perceived automatically.

  • Switch Your Phone to Spanish
Many students memorize the days of the week faster after changing the language of their phone or calendar.
When words constantly appear before the eyes, the brain naturally gets used to them.

It is better to memorize not separate words but the entire week:
  • lunes;
  • martes;
  • miércoles;
  • jueves;
  • viernes;
  • sábado;
  • domingo.
This makes it much easier to catch the sequence.
