According to John 20:1, Mary approached Jesus on the first day of the week. This is the first day (Sunday) after Passover and, according to Lev 23:9-14, the feast of firstfruits takes place on the day after the Sabbath following Passover.
The high priest would wave the sheaf of the firstfruits before the Lord. In waving the sheaf, it was a symbolic gesture of dedicating the harvest to the Lord.
Leviticus 23:14 And ye shall eat neither bread, nor parched corn, nor green ears, until the selfsame day that ye have brought an offering unto your God
The children of Israel could not partake of the harvest until after the high priest completed the wave of the firstfruits offering.
When Mary met Jesus, He was on His way to fulfill the offering of the firstfruits to His Father. Just as no one could partake of the grain until the wave offering had been completed, no one could partake in the joy of our resurrected Lord and Savior until He had appeared before His Father.
The waving of the sheaf also marked the start of counting the seven Sabbaths to Pentecost (Lev 23:15-22).
On the Day of Pentecost in the year our Lord and Savior Jesus Christ was resurrected from the grave, we have the first outpouring of Holy Spirit – Acts 2:1-4.
What a harvest hast been reaped from that offering of the firstfruits by our Lord and Savior Jesus Christ to our day and time. In fulfilling the feast of firstfruits, Jesus dedicated the harvest (all born again believers) to His Father.
(Don't know if this addresses the point in the OP, but it's what came to my mind as I read through the thread.)
