The Jewish “Feast of Weeks (Shavuot)” (May 30 – June 1) and the Christian feast of Pentecost (June 4) are celebrated on different days due to the 360 day Jewish calendar.
For the Jews, this time of celebration is known as Shavuot, which is the Hebrew word meaning “weeks.” This is one of three separate names that are used in Scripture to refer to this important Jewish feast. Each name emphasizes an important aspect of the feast as well as its religious and cultural significance to both Jews and Christians.
Besides being called the Feast of Weeks in Leviticus 23, this special feast celebration is called the “Day of the Firstfruits” in Numbers 28:26 and the “Feast of Harvest” in Exodus 23:16.
This important feast gets its name from the fact that it starts seven full weeks, or exactly 50 days, after the Feast of Firstfruits. Since it takes place exactly 50 days after the previous feast, this feast is also known as “Pentecost” (Acts 2:1), which means “fifty.”
It normally occurs in late spring, either the last part of May or the beginning of June. Unlike other feasts that began on a specific day of the Hebrew calendar, this one is calculated as being “fifty days to the day after the seventh Sabbath” (Leviticus 23:15–16; Deuteronomy 16:9–10).
Like other Jewish feasts, the Feast of Weeks is important in that it foreshadows the coming Messiah and His ministry. Each and every one of the seven Jewish Feasts signifies an important aspect of God’s plan of redemption through Jesus Christ.
In the New Testament, fire is associated with the presence of God (Hebrews 12:29) and the purification He can bring about in human life (Revelation 3:18). God’s presence and holiness are implied in the Pentecostal tongues of fire.
Indeed, fire is identified with Christ Himself (Revelation 1:14; 19:12); this association naturally underlies the Pentecost gift of the Holy Spirit, who would teach the disciples the things of Christ (John 16:14).
