Of course we can’t even agree if it’s the third or the fourth day
Most of my life I wondered why it’s called “middle of the week” when actually Thursday’s the day with an equal number of days in a week coming before and after. I often thought maybe weekend’s subtracted. Only in my late 20s I learned that there are places where the first day of the week is Sunday lol
The funny part is the green countries in this map don’t start the week on a sunday. I guess they used to and the name stayed
Estonia is incorrect as well, in Estonian Wednesday would be “kolmapäev”, which translates to “third day”
In Basque language the third day of the week is called asteazkena, “the last day” (aste=week azken=last) because the ancient Basque weeks only had three days. So astelehena= first day of the week = Monday. Asteartea=middle day = Thursday.
In Kosovo the majority is Albanian so they would say Merkure.
For Northern Africa it’s Fourth day too (in Arabic)
