The Babylonians were the first authors of our modern week, naming their days after the planets. Then came the Anglo-Saxons who took over and named Tuesday to Friday after their gods, while keeping the Roman's names for the other days.
Monday gets its name from the Anglo-Saxon word "mondandaeg" which translates to "the moon's day". Despite what we believe, Monday is actually the second day of the week. That's right, second. Which brings us to the third day of the week:
Tuesday is the third day of the week, even though we all like to think of it as the second. Tuesday gets its name from the Anglo-Saxon’s god of war Tiu, also known as Tyr to the Vikings. The Romans named their third day of the week after their god of war, Mars. That is why romantic languages like Spanish, French and Italian all have similar names for Tuesday: martes, mardi, and martedi. When the Anglo-Saxons took up the seven-day week, they acted like super big copy cats and named their third day of the week after their god of war as well. Or maybe there is just something about Tuesdays that makes calendar-makers super feisty?
