Thanks for the question.
We're still learning about setting up the listing. Somehow we stumbled on the rule setting. We set the rule up and called it "weekend". Then we clicked on one Saturday. We could remember the steps wrongly. Later on we found all the Fridays and Saturdays selected though we thought it should be Saturdays and Sundays. How did it know that when we called it "weekend" it meant Fridays and Saturdays. We are now not too sure what step we did though.
So if we want a different rate for public holidays, should we set it on the eve of the public holidays or on the very days?
We tested it yesterday. We also found that turning on the smart pricing seems to restoring the rate to its pre-set minimum if the rate had been manually set. We're still not too sure. It is very confusing. There is no guide. To the programmer, that might be self-explanatory but they are not. They are busy people but they forget we're busy people too.
