Just in case - comparing the day of week in a string format (like “Monday” in your example) most probably won’t work correctly if user locale (e.g. language) is different from English. The reason is that the date will be written in user’s language and comparison won’t work.
I’d suggest calculating DayID and make the visibility condition based on that, see here for example: API to get day of week? (Monday, Tuesday, etc) - #3 by Victor
