Confessions Are OK on Holy Saturday

The document Paschale Solemnitatis (75) explicitly permits the sacrament of confession on Holy Saturday, but it does not obligate priests to offer confessions on that day.

Of course, depending on how many priests are in a parish and how much help they have setting up and breaking down for all the days of the Triduum, it might not be feasible for the priest to hear confessions on that day.
