Customize weekend days

[Franklyn-S]

I'd like to customize weekend days, for example, disable them and/or change their color. How can I do this? Thanks in advance.

I found a way to change the layout of the weekend days: .calendar__day:nth-child(7n+1), .calendar__day:nth-child(7n) { background-color: yellow; }
