Hi everyone
Do you still remember when we were talking about the origin of the English weekdays? 
I’m sure the answer is ‘Yes’. That’s why I got this table for you.
The most important thing to take into account is the fact that in English we begin the week on Sunday and not on Monday as we do in Spanish. With regards to the origin of these words (their etymology), as you can see on the table, there’s a nice mixture of both Anglo-Saxon and Latin sources.
Hope you enjoy it!
