Biblical festivals in the new testament

While the New Testament does not provide a comprehensive list of all the biblical festivals, it does mention several festivals that were observed during the time of Jesus and the early Christian church. Here are some of the biblical festivals mentioned in the New Testament:

1. Passover (Pesach): Celebrated on the 15th day of Nisan (March/April), Passover commemorates the Israelites' deliverance from slavery in Egypt. Jesus celebrated the Passover with his disciples in the Upper Room (Luke 22:7-20) and instituted the Lord's Supper.
2. Unleavened Bread (Chag HaMatzot): This festival, also known as the Feast of Unleavened Bread, was celebrated immediately after Passover. It lasted for seven days and was a time of remembrance for the Israelites' hasty departure from Egypt. The early Christian church observed this festival, as seen in 1 Corinthians 5:7-8.
3. Pentecost (Shavuot): Celebrated on the 50th day after Passover, Pentecost commemorates the giving of the Law on Mount Sinai. The New Testament records the events of Pentecost in Acts 2:1-47, where the Holy Spirit was poured out on the disciples and other believers.
4. Tabernacles (Sukkot): This festival, celebrated on the 15th day of Tishrei (September/October), commemorates the Israelites' journey through the wilderness and their dwelling in tents. Jesus attended the Tabernacles festival in Jerusalem (John 7:2-10) and engaged in a controversy with the Pharisees about the proper way to worship (John 7:14-24).
5. Dedication (Hanukkah): This eight-day festival, celebrated on the 25th day of Kislev (December), commemorates the rededication of the Temple in Jerusalem after the Maccabean Revolt. The New Testament does not mention Hanukkah specifically, but it is possible that Jesus and his disciples may have celebrated it.
6. Feast of the Tabernacles (Sukkot): This festival, celebrated on the 15th day of Tishrei, was a time of rejoicing and thanksgiving for the harvest. Jesus attended the Feast of Tabernacles in Jerusalem (John 7:2-10) and engaged in a controversy with the Pharisees about the proper way to worship (John 7:14-24).

It's worth noting that the New Testament does not provide a comprehensive list of all the biblical festivals, and some festivals may have been observed by the early Christian church without being explicitly mentioned in the New Testament. Additionally, the early Christian church began to observe new festivals, such as Easter and Christmas, which are not mentioned in the New Testament.
