When did the "Holy Spirit descend?" I mean the date.
7 weeks after the start of Passover - at the Jewish Pentecost celebration. That year it was a few weeks after Jesus' resurrection. The disciples were gathered for the feast when the Spirit came on them. The Christian Pentecost is now celebrated 40 days after Easter to celebrate that. The dates aren't exact but close enough.
Since nobody knows what year that happened, figuring the exact date is impossible.
