In the UK this would probably be explained by saying something like:
"Wednesdays are overtime-free days."
However, what is more important is why these days are free of overtime? Was iot a management decision - or perhaps a union decision? In the UK such comment would immediately give rise to the question: "Why?'
"Wednesdays are always overtime-free because the workers union forced the company to ban overtime on Wednesdays."
イギリスでは、おそらくこのように表現できると思います。
"Wednesdays are overtime-free days."
水曜日は、ノー残業デー。
ただ、「水曜日はノー残業デー」とイギリスで話すと、どうしてこの日だけ残業がないの？会社のルールなの？労働組合のルールなの？という疑問があがるはずです。国によって働く環境は違いますから、このように少し説明を付け足すといいかもしれません。

水曜日は、労働組合が残業を禁止しているから、ノー残業デーなんだ。
