Of course it does. Hebrews does not indicate the day was merely changed. It indicates the day was abolished with the passing away of the old covenant with the priesthood and sacrificial rituals.
"For I will be merciful to their unrighteousness, and their sins and their lawless deeds I will remember no more." In that He says, "A new covenant," He has made the first obsolete. Now what is becoming obsolete and growing old is ready to vanish away." (Heb. 8:12,13)
All of the pold covenant ritual days passed away. There is no other way to read the words written in Hebrews.
There is another way to read Hebrews, the proper way. You're passing away things that Hebrews does not.
The Levitical priesthood is changed. Animal sacrifices are changed. These are LISTED in Hebrews. For whatver reason, you wish to add God's holy days to this list without any biblical justification.
The fault of the "old covenant" wasn't with God's end of the deal. A perfect God does nothing wrong. The fault was with the people who were part of God's covenant:
Heb 8:7 For if that first covenant had been faultless, then should no place have been sought for the second.
Heb 8:8 For finding fault with them, he saith, Behold, the days come, saith the Lord, when I will make a new covenant with the house of Israel and with the house of Judah:
Heb 8:9 Not according to the covenant that I made with their fathers in the day when I took them by the hand to lead them out of the land of Egypt; because they continued not in my covenant, and I regarded them not, saith the Lord.
Heb 8:10 For this is the covenant that I will make with the house of Israel after those days, saith the Lord; I will put my laws into their mind, and write them in their hearts: and I will be to them a God, and they shall be to me a people:
Under the new covenant, with the sacrifice of Christ, man becomes able to obey the laws of God by relying on the spirit of God.

BTW, do you celebrate Christmas and Easter? If so, wny? If not, why not?
I also understand, through the letters of Paul, that those who confess the name of Jesus Christ as Lord and Savior are thus adopted into the promise made to Abraham. Abraham was saved by faith. He demonstrated his faith through works. This is a good pattern to live by.
Once I came to the truth about the man made, Rome decreed holidays of this world, I could no longer keep them. It is not lineear to me to "protest" Rome's authority, yet keep to its practices.
