According to the Bible, the only time(s) that should be recognized or worshiped are the Sabbaths, the Passover, Leviticus 23. Any other "holy days" such as Ash Wednesday, Valentine's Day, Easter, Lent, Christmas and Sunday are UNHOLY days and are the devil's creation and an abomination to the creator of the heaven's and earth. They are all mystery religions from Sumer or Mesopotamia and are detestable.
