You know, when you speak language where the word for Tuesday is literally "Seconder" and the word for Friday is "Fifter", it's really difficult to accept that starting to number the days of the week from Sunday is a sensible thing.
• Sunday: “no work”
• Monday: “[first] after Sunday”
• Tuesday: “second [after Sunday]”
• Wednesday: “middle”
• Thursday: “fourth [after Sunday]”
• Friday: “fifth [after Sunday]”
• Saturday: “sabbath”
Treating the work week as the start of the calendar week is a 20th century invention, as is the five‐day work week. Historically, Slavic calendars began on Sunday: https://www.russianhistorymuseum.org/wp-content/uploads/2025...
