No. "Lent" is part of Christendom's "Easter" commemoration, which has no actual connection with true Christianity or the Bible.
In fact, the Bible is rather obvious in demonstrating that there are fundamental differences between the Memorial which Christ Jesus instituted and the so-called "Easter" which Christendom adopted from pagan worship of the Anglo-Saxon goddess Eostre (or Oestre). While most Easter celebrations merely repackage pagan fertility festivals and concentrate on eating, decorating, and frivolity, the Last Supper focuses on the value of Christ's sacrifice and the sober obligation of Christianity.
.. ..(Matthew 15:6-9) You have made the word of God invalid because of your tradition. 7 You hypocrites, Isaiah aptly prophesied about you when he said, 8 ‘This people honors me with their lips, yet their heart is far removed from me. 9 It is in vain that they keep worshiping me, because they teach commands of men as doctrines.’”
The most significant "Memorial" one could observe is, of course, the Memorial of Christ's death. It is sometimes called "the Last Supper" or "the Lord's Evening Meal".
.. ..(1 Corinthians 11:23-25, NWT) The Lord Jesus in the night in which he was going to be handed over took a loaf... Keep doing this in remembrance of me.” 25 He did likewise respecting the cup.. Keep doing this... in remembrance of me.”
.. ..(1 Cor 11:24, 25, NEB) "Do this as a memorial of me.”
Christ Jesus himself personally celebrated and explained the significance of that Last Supper to his followers (see Matthew 26:26-29). Apparently Jesus Christ established the occasion to supercede the Jewish Passover, which occurs after sunset on the 14th of Nisan (a month of the Jewish calendar).
.. ..(Luke 22:14-16) At length when the hour came, he reclined at the table, and the apostles with him. 15 And [Jesus] said to them: “I have greatly desired to eat this passover with you before I suffer; 16 for I tell you, I will not eat it again until it becomes fulfilled in the kingdom of God.
Sadly, it is only a minority of professed Christians who follow the BIBLICAL pattern for the Last Supper which was established by Christ himself. Sadly, most of Christendom ignores Christ's celebration and instead follow unrelated human traditions which purport to honor Christ, but in ways unconnected with what Jesus Christ established.
