@nikitonsky It's just how the week was from the Babylonian times 🤷 Weekend is a relatively new invention, and it covers Saturday to suit Jews and Sunday to suit Christians.

Realistically though, I totally agree that it is as insane as the imperial measurement system :) Luckily, ISO-8601 defines the first day of the week as Monday.

My comment referenced this proposed calendar: https://en.wikipedia.org/wiki/International_Fixed_Calendar , which makes a lot of sense, apart from the chosen week start day.
