Chinese numbers the days of the week, starting from 1 for Monday, but with a special name for Sunday, it seems.

I don't speak, or read, Chinese, but translate.google.com confirms this.

I am often curious about how Chinese expresses something, so I ask translate.google.com to translate an expression into Chinese, then I change the direction of translation and insert newlines between the Chinese characters. It's not a very reliable way of investigating how Chinese works, of course, but it's a lot faster than trawling through wiktionary.org. If anyone knows of a better way of getting an answer to that sort of question, please reply here!

The Quakers numbered their weekdays and also their months, to avoid referencing foreign gods in their calendar. https://www.swarthmore.edu/friends-historical-library/quaker...

Days of the week in Hebrew are numbered from Sunday "Yom Rishon" (First day, lit. "Head Day") to Friday "Yom Shishi" (Sixth Day). "Saturday" is "Shabbat" ("sabbath")

Czech but only for Thursday and Friday. And they're fourth and fifth, so it's off by one.
