In this article, we'll look at each day of the week, explore their interesting etymology, and compare them with their English counterparts. By learning about the days of the week, you'll be able to confidently use them in all kinds of conversations!

Etymology of the Days of the Week in Spanish

The Spanish language has seven days of the week:

Lunes Monday
Martes Tuesday
Miércoles Wednesday
Jueves Thursday
Viernes Friday
Sábado Saturday
Domingo Sunday
Lunes Monday
Martes Tuesday
Miércoles Wednesday
Jueves Thursday
Viernes Friday
Sábado Saturday
Domingo Sunday

And, all of them have a very interesting etymology.

  1. Lunes is derived from the Latin ‘dies Lunae,’ literally meaning “Day of the Moon.”
  2. Similarly, Martes comes from “dies Martis” or “Day of Mars,” which is in reference to the Roman god of war and agriculture.
  3. Miércoles originates from the Latin “dies Mercurii” meaning “Day of Mercury,” referencing the messenger god of the Roman pantheon.
  4. Meanwhile, Jueves is derived from “dies Jovis” or “Day of Jupiter,” who was the chief deity in the Roman pantheon.
  5. Viernes comes from Latin “dies Veneris” or “Day of Venus,” who was goddess of love and beauty.
  6. Also, Sábado is derived from “dies Saturni” or the “Day of Saturn,” god of agriculture and time in Roman mythology.
  7. Lastly, Domingo comes from “dies solis,” meaning “Day of the Sun.”

Comparison With the Days in English

The English language has different roots from Spanish, and so the origins of this vocabulary is completely different. The English days of the week have been derived from Germanic traditions, with their names all having Anglo-Saxon roots.

  • Sunday is derived from the Old English "sunnandæg" (meaning day of the sun), and Monday, from "mōnandæg" (which translates to "moon day).
  • Tuesday comes from the Old English word "Tiwesdæg," which means "Tiw's day." Tiw was the name of a Germanic god of war, who was later identified with the Norse god Tyr.
  • Wednesday has roots from the Middle English “wednesdei” and the Old Germanic translation of “Wodanaz dagaz,” both referring to Woden or Odin, who was a chief god in Norse mythology.
  • Thursday comes from the Old English word "Þunresdæg," which means "Thor's day." Thor was the god of thunder and lightning in Norse mythology and was one of the most important gods in the pantheon. He was known for his strength, courage, and his mighty hammer Mjölnir.
  • Friday has its roots coming from Old English and Old High German translations of “frigedæg," or "Frigg's day.” Frigg was the wife of Odin and is often compared to the Greek goddess Hera.
  • Finally, Saturday means “Saturn’s day," in reference to the Roman deity of agriculture, Saturn.

Overall, although the English days of the week have their roots in Anglo-Saxon, Spanish days of the week have both Germanic and Latin origins. In comparison to English terms, some words are very similar, such as the Spanish word “lunes,” which means moon day in both languages.

How to Ask ¿Qué Día Es Hoy?

Now, let's cut to the chase and understand the best phrases to say the days of the week. In Spanish, there are different ways to ask "what day is it today?". Let's have a look at some examples:



¿Qué día es hoy?

What day is it today?

¿Qué día es hoy de la semana?

What day of the week is today?

¿En qué día estamos?

What day is it today?

¿En qué fecha estamos?

What date is it today?

Note: You may have noticed that both "¿qué día es hoy?" and "¿en qué día estamos?" have the same translation in English. This happens because the second example is a very common way to ask what day is it today (particularly in South America), though the grammar is not totally correct. A literal translation would be "in what day are we today?".
