The Messianic Jewish calendar typically includes both Jewish and Christian holidays, as well as events that are significant to the history and theology of the movement.

Some of the major Jewish holidays observed by Messianic Jews include:

• Rosh Hashanah: the Jewish New Year, which is observed in the fall and marks the beginning of the High Holy Days.
• Yom Kippur: the Day of Atonement, which is observed ten days after Rosh Hashanah and is a time for reflection and repentance.
• Sukkot: the Feast of Tabernacles, which is observed in the fall and commemorates the Israelites’ journey through the wilderness.
• Hanukkah: the Festival of Lights, which is observed in the winter and commemorates the rededication of the Temple after the Maccabean revolt.
• Passover: the holiday that commemorates the Israelites’ liberation from slavery in Egypt.
• Shavuot: the holiday that commemorates the giving of the Torah at Mount Sinai.

In addition to these Jewish holidays, Messianic Jews also observe Christian holidays such as Christmas and Easter, as well as events that are significant to the history and theology of the movement. These may include:

• The Feast of Firstfruits: a holiday that celebrates the resurrection of Jesus and is observed on the Sunday after Passover.
• Pentecost: a Christian holiday that commemorates the descent of the Holy Spirit on the disciples of Jesus.
• The Feast of Trumpets: a holiday that is associated with the return of the Messiah and is observed on Rosh Hashanah.
• The Day of Atonement: a holiday that is associated with the forgiveness of sins and is observed on Yom Kippur.

Messianic Jews may also observe other events that are significant to the history and theology of the movement, such as the anniversary of the founding of the first Messianic Jewish congregation in the United States in 1968.

It’s important to note that the specific practices and observances of Messianic Judaism can vary depending on the individual or community. Some Messianic Jewish communities may follow a more traditional Jewish approach, while others may incorporate more Christian practices.
