Answer 1

You can attach a tag to the particular day using calevent_create() and then use tag_config() to change the background color using the tag:

Below is an example:

import datetime

...

day = datetime.date(2020, 7, 20)
cal.calevent_create(day, "", tags="hi")
cal.tag_config("hi", background="red")
