This day has a dual meaning
This feast day however has a dual meaning, because it is related to Shavuot / Pentecost.
During Shavuot, all Jewish men had to go to Jerusalem for the feast of weeks. About 200 years before Yeshua, the rabbis added another meaning to Shavuot. They started linking it to the event on Mount Sinai where Yahweh gave the law (Torah) to Moses.
The authors of the New Testament linked the pouring out of the Holy Spirit on Pentecost (which they called Shavuot) with the events on Mount Sinai. At both these events there were visible signs. We further know there will be visible signs with the return of our Messiah.
(Exo 19:17) And Moses brought forth the people out of the camp to meet with God; and they stood at the nether part of the mount.
(Exo 19:18) And mount Sinai was altogether on a smoke, because the LORD descended upon it in fire: and the smoke thereof ascended as the smoke of a furnace, and the whole mount quaked greatly.
(Exo 19:19) And when the voice of the trumpet sounded long, and waxed louder and louder, Moses spake, and God answered him by a voice.
(Act 2:2) And suddenly there came a sound from heaven as of a rushing mighty wind, and it filled all the house where they were sitting.
(Act 2:3) And there appeared unto them cloven tongues like as of fire, and it sat upon each of them.
(Act 2:4) And they were all filled with the Holy Ghost, and began to speak with other tongues, as the Spirit gave them utterance.
This dual meaning was therefore not questioned by the disciples of Yeshua, but accepted as a given. This is therefore the background in which the New Testament was drawn up.
For the Jewish believers, the events at Pentecost was therefore the second coming of the Law (Torah).
(Jer 31:32) Not according to the covenant that I made with their fathers in the day that I took them by the hand to bring them out of the land of Egypt; which my covenant they brake, although I was an husband unto them, saith the LORD:
(Jer 31:33) But this shall be the covenant that I will make with the house of Israel; After those days, saith the LORD, I will put my law in their inward parts, and write it in their hearts; and will be their God, and they shall be my people.
(Jer 31:34) And they shall teach no more every man his neighbour, and every man his brother, saying, Know the LORD: for they shall all know me, from the least of them unto the greatest of them, saith the LORD: for I will forgive their iniquity, and I will remember their sin no more.
(Jer 32:37) Behold, I will gather them out of all countries, whither I have driven them in mine anger, and in my fury, and in great wrath; and I will bring them again unto this place, and I will cause them to dwell safely:
(Jer 32:38) And they shall be my people, and I will be their God:
(Jer 32:39) And I will give them one heart, and one way, that they may fear me for ever, for the good of them, and of their children after them:
(Jer 32:40) And I will make an everlasting covenant with them, that I will not turn away from them, to do them good; but I will put my fear in their hearts, that they shall not depart from me.
The "new covenant" was therefor given to the house of Israel and the house of Judah.
At first the Torah was given on Mount Sinai (written on 2 tablets of stone), and the second Torah was written on the hearts (inward parts) of men.
To whom is this new covenant given?
We receive access to this new covenant through Yeshua our Messiah.
(Heb 10:11) And every priest standeth daily ministering and offering oftentimes the same sacrifices, which can never take away sins:
(Heb 10:12) But this man, after he had offered one sacrifice for sins for ever, sat down on the right hand of God;
(Heb 10:13) From henceforth expecting till his enemies be made his footstool.
(Heb 10:14) For by one offering he hath perfected for ever them that are sanctified.
(Heb 10:15) Whereof the Holy Ghost also is a witness to us: for after that he had said before,
(Heb 10:16) This is the covenant that I will make with them after those days, saith the Lord, I will put my laws into their hearts, and in their minds will I write them;
(Heb 10:17) And their sins and iniquities will I remember no more.
(Heb 10:18) Now where remission of these is, there is no more offering for sin.
Yeshua told His disciples to wait in Jerusalem for the Promise from the Father.
The disciples were all in one accord on the Day of Pentecost where they received the Holy Spirit.
This is then the reason why this day must be remembered as a Feast Day unto Yahweh. Just as the people of Israel were fed with Manna from the heaven in the wilderness, so are we daily fed with the spirit of Yahweh which he poured out on Yeshua when he was baptised.
(Mat 3:17) And lo a voice from heaven, saying, This is my beloved Son, in whom I am well pleased.
(Luk 3:22) And the Holy Ghost descended in a bodily shape like a dove upon him, and a voice came from heaven, which said, Thou art my beloved Son; in thee I am well pleased.
(Joh 1:33) And I knew him not: but he that sent me to baptize with water, the same said unto me, Upon whom thou shalt see the Spirit descending, and remaining on him, the same is he which baptizeth with the Holy Ghost.
(Joh 1:34) And I saw, and bare record that this is the Son of God.
Yeshua poured this same Spirit out on His disciples when he sent them to proclaim the gospel of the Kingdom of His Father.
(Joh 20:22) And when he had said this, he breathed on them, and saith unto them, Receive ye the Holy Ghost:
(Joh 20:23) Whosoever sins ye remit, they are remitted unto them; and whosoever sins ye retain, they are retained.
On the Day of Pentecost many of the people present were filled with the same Spirit.

We all thus follows Yahweh through Yeshua
The people of Israel lived under different circumstances and had to keep the feasts according to prescribed methods.
All the feasts pointed to the Promised Messiah and is all fulfilled by Yeshua with His death and resurrection. We must remember the feast days and show our gratitude for what Yeshua has done for us.
The feast days which are followed according to the solar/lunar calendar is therefore not according to our Creators Calendar and therefore not His feast days.
Commemorate at least the feast days on the correct day,
