Tomorrow is St. Joseph’s Day, which, being a Solemnity, means that all normal Lenten rules are set aside. But liturgically, Solemnities begin the evening before. In the universal Church, St. Joseph’s Day is a Holy Day of Obligation, though not in the USA. Going to Mass this evening would satisfy the obligation.
So, could one argue that after 4:00 p.m. today, it would be permissible to eat meat, or to set aside any other Lenten penances? Well, yes, one could argue that. But would the argument hold?
Methinks the answer is no.
