And what exactly does that have to do with where the specific word “Pentecost” originated and became known for that event? Is Shavout somehow connected to 50 days after Easter timeline? I’m missing the context in your reply of how that event became named as “Pentecost”?

Pentecost happened on Shavout. 50 Days after YESHUA was raised from the dead

• Pentecost, or the Feast of Weeks (in Hebrew, Shavout), was one of three major Jewish pilgrim feasts, celebrated seven weeks after Passover (Deuteronomy 16:16). Devout Jews from all over the known world would be in Jerusalem for these two feasts (verses 9-11). Originally a harvest festival where God’s people would offer him the first fruits (best part) of the harvest, it came to be also a commemoration of the giving of the Law to Moses on Mt. Sinai on the fiftieth day after the Exodus from Egypt (from the Greek Petekoste, meaning “fiftieth”).
• So there was a Jewish feast of Pentecost before there was a Christian one. The Jewish feast was celebrated 50 days after Passover, but the Christian feast is celebrated 50 days after Easter. Christians now celebrate Pentecost as the “birthday” of the Church, and a celebration of the giving of the New Law of the Spirit written on the hearts of believers (Jeremiah 31:31-34; 2 Corinthians 3:4-6) as was promised to the Apostles by Our Lord (John 15:26;16:13; 20:22, Luke 24:49).
