Does any denomination commemorate as Feast, events of the Old Testament?

Muslims across the world celebrated on 10th July, the Eid al-Adha to commemorate the obedience that Abraham showed to God's Will,by almost sacrificing his son. Abraham's obedience would later be perfected by Jesus who sacrificed himself on the Cross. So we have the Good Friday. On Maundy Thursday, we remember the Passover of the Israel by virtue of Jesus having celebrated it. Other than that, the Catholic Church is not known to have been commemorating OT events, say the Feast of the Commandments. My question therefore is: **Are there any denominations which commemorate as Feast, events of the Old Testament?**
