Same problem with my sites.
For example – https://ld-landscape.co.il/public/
when the week start on Sunday, you still color Saturday and Sunday as the weekend. I think it should be Friday and Saturday (It will simplify your code).
RTL – I’m still checking why the text is not justified to the right.
No really helps.
It’s better putting “DEFAULT CHARSET=utf8;” in every “CREATE TABLE”.
