Exodus 12:14
“This day shall be for you a memorial day, and you shall keep it as a feast to the Lord; throughout your generations, AS A STATUTE FOREVER, you shall keep it as a feast.
The Catholics are right!
What propaganda ever led you to believe the Jewish festivals were only for a time and a season?
Gal 4:8-11
8 Formerly, when you did not know God, you were slaves to those who by nature are not gods. 9 But now that you know God—or rather are known by God—how is it that you are turning back to those weak and miserable forces? Do you wish to be enslaved by them all over again? 10 You are observing special days and months and seasons and years! 11 I fear for you, that somehow I have wasted my efforts on you.
