What is involved here?
The USCCB says:
Fridays Throughout the Year In memory of Christ's suffering and death, the Church prescribes making each Friday throughout the year a penitential day. All of us are urged to prepare appropriately for that weekly Easter that comes with each Sunday.
While that's a bit vague, even weak in merely "urging" us, the Code of Canon Law is not so weak:
Canon 1251: Abstinence from meat, or from some other food as determined by the Episcopal Conference, is to be observed on all Fridays, unless a solemnity should fall on a Friday.
And, keeping in mind that Canon 1251 has never been abrogated:
Canon 33 §1 General executory decrees, even if published in directories or other such documents, do not derogate from the law, and any of their provisions which are contrary to the law have no force.
§2 These decrees cease to have force by explicit or implicit revocation §2 These decrees cease to have force by explicit or implicit revocation by the competent authority, and by the cessation of the law for whose execution they were issued. They do not cease on the expiry of the authority of the person who issued them, unless the contrary is expressly provided.
So, enjoy that cheeseburger today - but do keep in mind WHY you would normally NOT have that cheeseburger and that a solemnity is a "gift" as every Sunday is.
