Yes. There are three current ones, and one that was present in Christianity in the past.
First, the 7-say week ending with a Sabbath is a Jewish tradition practiced by Christians. The Christians changed the last day of the week from Saturday to Sunday, but still celebrate a weekly holy day, and some call it a Sabbath Day.
Second, the Last Supper was a Passover (Pesach) feast, and each Easter is a commemoration of that Passover. Also, each communion is a remembrance of Passover and of the traditional Jewish blessings of wine and bread as God's gifts. (When Jesus raised the wine and bread, he said the traditional Jewish blessings, and we remember this at each communion.)
Third, Pentecost is a Jewish holiday. Greek Jews called it Pentecost (50 days after Passover) (the day God gave the Pentateuch, the original Jewish bible, the five books of Moses. At the first Pentateuch after the first Easter (Jesus' death and resurrection), the Holy Spirit descended on the congregation of Jewish Christians. So, the Christian Pentecost is the celebration of the arrival of God's Word, the Torah, and also the Holy Spirit.
Fourth, early Christians celebrated the end of the old year and beginning of the new year with Yom Kippur (the day of Atonement) and Rosh Hashanah (the head of the year) in the fall, as Jewish people still do.
