Pentecost
The biblical definition of the Pentecost is given in Lev 23:15-16 "And you shall count for yourselves from the day after the Sabbaths [the day after is Sunday], from the day of your bringing the wave offering's sheaf - there shall be seven full weeks. Until the day after the seventh Sabbath you shall count fifty days; then you shall present a new grain offering for KYRIOS."
The application of this verse to the biblical calendar is best understood when comparing it with the Jubilee year.
A Jubilee Year had been
- Announced in the year before the Jubilee Year (Day of Atonement).
- Announced in the 49th year after the Sabbath Year preceding the previous Jubilee Year.
- Celebrated in the 50th year after the Sabbath Year preceding the previous Jubilee Year.
- Celebrated every 49th year, always in the year following the 7th Sabbath Year (7-14-21-28-35-42-49).
The exact same pattern applies for Pentecost. It is celebrated on the 49th day after the First Fruits which occurs 1 day after the Weekly Sabbath, therefore on the 50th day after this Weekly Sabbath immediately following the Passover week.
The Jubilee Year occurs in the first year after the 7th Sabbath Year, while the Pentecost occurs on the first day after the 7th Sabbath Day.
