The days of the week as we know them today in Portuguese, segunda-feira, terça-feira, quarta-feira, quinta-feira, sexta-feira, sábado and domingo originated in the city of Braga.
Most of the Latin languages have the days of the week dedicated to the Roman gods, as is the case of Spanish and English, for example, with Saturday (Saturn) or Miércoles (Mercury). This origin clearly comes from the Roman empire that dominated much of Europe and that had influence in countries like the United Kingdom or Spain that later became maritime powers, spreading its presence in practically the whole world. Portugal enters this equation as already mentioned. The Roman gods are replaced by São Martinho de Dume, the bishop of Braga who wanted to fight Roman paganism by changing the names for liturgical feasts.
The days began to have the word Feria which meant feast, and along with the numbers. The days were called Dominica dies, Feria Secunda, Feria Tertia, Feria Quarta, Feria Quinta, Feria Sexta, Sabbatum and they evolved so that Feria was transformed into Feira and passed after the number, Secunda to Segunda and so on. , with the exception of Tuesday which is not Terceira as it kept the original Latin pronunciation of Tertia.
Like Portugal’s maritime expansion, it was also the language and so the names of the week are the same in all Portuguese-speaking countries, from Brazil to Angola or Mozambique.
