We must no longer keep the Holy Days of God just due to the Law. We must keep the Holy Days / Holidays of God, Of the Government/Kingdom of God because we desire and look forward to these days and a closer intimate relationship with God. We should count the days to Pentecost. We SHOULD count the days to Pentecost! Not because it's a law. But because we should be looking forward to this celebration. As other people count the days to Christmas, Christians should count the days to Gods Appointed Feast.

Pentecost represents the Firstfruits of Gods Harvest. The First Harvest. The Spring Harvest. The ekkelsia that is being grown and gathered in this time. The Glorified Power of the Holy Ghost was given on the day of Pentecost in Acts. They were told by Jesus to wait there for the Power from on High. They were gathered together. They were there to keep the Feast of Weeks / Feast of Firstfruits as instructed in Lev. 23 and other places in the Bible. They were in obedience to the Law of God. They received the Gift of the Holy Ghost, filled with Supernatural Power from Heaven, spoke with the gift of unknown tongues and began what is known today as the Church on that day of Pentecost. This year, Let's be gathered together, waiting (in prayer) for the Power from Heaven to pour out on us!

HOW TO COUNT Pentecost:

Lev 23:15 And ye shall count unto you from the morrow after the sabbath (during week of unleavened bread), from the day that ye brought the sheaf of the wave offering; seven sabbaths shall be complete:
Lev 23:16 Even unto the morrow after the seventh sabbath shall ye number fifty days; and ye shall offer a new meat offering unto the LORD.
Lev 23:20 And the priest shall wave them with the bread of the firstfruits for a wave offering before the LORD, with the two lambs: they shall be holy to the LORD for the priest.
Lev 23:21 And ye shall proclaim on the selfsame day, that it may be an holy convocation unto you: ye shall do no servile work therein: it shall be a statute for ever in all your dwellings throughout your generations.
-Therefore it is very easy to see that the Pentecost/Feast of Firstfruits/Feast of Weeks always occurs on Sunday, the morrow after the 7th Sabbath counting from the sabbath of Unleavened bread.

ANY other day is in rebellion to Gods Written Word!

Gods Word has authority OVER any tradition of man or publication of man.

To understand more about Pentecost:
The following is a quotation from: http://www.ptgbook.org/index.html and I do agree FOR THE MOST PART with what he says about this particular issue except that it is NOT even to even. To learn Why it is NOT even to even, please read the When Does the Day start article. Also, the first day of the month when to start counting the days of the month should be according to the New Moon events.

Pentecost - "In the Old Testament, it is called the Feast of Weeks (Deuteronomy 16:9-11) and is sometimes called the Feast of Firstfruits (Numbers 28:26). It's description is given in Leviticus 23:15-21. It is observed 50 days from the Sabbath that falls during the Days of Unleavened Bread, so it always falls on a Sunday. In the New Testament, it is called Pentecost (Acts 2:1), which means, I believe, "count fifty". In the Old Testament, it is connected with the small, early summer harvest. In the New Testament, it is associated with the coming of the Holy Spirit. Before Jesus was crucified, He told His disciples that they would receive the gift of the Holy Spirit. "These things I have spoken to you while being present with you. But the Helper, the Holy Spirit, whom the Father will send in My name, He will teach you all things, and bring to your remembrance all things that I said to you" (John 14:25-26). After His resurrection and before His ascension into heaven, Jesus told His disciples to wait for the Holy Spirit. "And being assembled together with them, He commanded them not to depart from Jerusalem, but to wait for the Promise of the Father, 'which,' He said, 'you have heard from Me; for John truly baptized with water, but you shall be baptized with the Holy Spirit not many days from now' " (Acts 1:4-5). The actual coming of the Holy Spirit is recorded in Acts 2:1-4, "When the Day of Pentecost had fully come, they were all with one accord in one place. And suddenly there came a sound from heaven, as of a rushing mighty wind, and it filled the whole house where they were sitting. Then there appeared to them divided tongues, as of fire, and one sat upon each of them. And they were all filled with the Holy Spirit and began to speak with other tongues, as the Spirit gave them utterance." The Holy Spirit helps a person understand the Bible and understand spiritual knowledge in a way that the natural mind of man is not able to do. I already covered the verse above where Jesus said that the Holy Spirit would help His disciples to remember the things Jesus taught them. Note also these scriptures. "But God has revealed them to us through His Spirit. For the Spirit searches all things, yes, the deep things of God. For what man knows the things of a man except the spirit of the man which is in him? Even so no one knows the things of God except the Spirit of God" (1 Corinthians 2:10-11). Note that Paul said that there is a spirit in man. Mr. Armstrong explained that the vast difference in intelligence between humans and that of animals such as dogs, chimpanzees, elephants, and dolphins is due to a spirit in every human that God has added to the human brain to empower the human mind with a quality of intellect that animals do not have. He called this the "human spirit". But just as the human spirit empowers humans to understand physical knowledge, such as knowledge about science, engineering, literature, and languages, in a way that animals are not able to understand, so the Spirit of God empowers a Christian to understand, as Paul put it, "the deep things of God" in a way that the human mind, apart from God's Spirit, cannot understand. The Holy Spirit also empowers a Christian. "For God has not given us a spirit of fear, but of power and of love and of a sound mind" (2 Timothy 1:7). You can study the gospel accounts and the book of Acts to see how the disciples behaved differently, more courageously for example, after they received the Holy Spirit than before. When Jesus was taken to be crucified, almost all His disciples left Him, even though they previously said they would die with him, and even Peter denied Christ. But after they received the Holy Spirit they were willing to suffer and even die for Christ. It is actually the presence of the Holy Spirit in the mind that makes one a Christian and a member of God's true Church. Paul wrote, "But you are not in the flesh but in the Spirit, if indeed the Spirit of God dwells in you. Now if anyone does not have the Spirit of Christ, he is not His. And if Christ is in you, the body is dead because of sin, but the Spirit is life because of righteousness. But if the Spirit of Him who raised Jesus from the dead dwells in you, He who raised Christ from the dead will also give life to your mortal bodies through His Spirit who dwells in you" (Romans 8:9-11). The conditions for receiving the Holy Spirit are repentance and faith in God and in Christ, and baptism by immersion in water as a symbol of our faith in the sacrifice and resurrection of Christ for the forgiveness of sins and a symbol of the burial of the old self. God then gives the gift of His Holy Spirit upon the laying on of hands by the ministry. Notice, "Then Peter said to them, 'Repent, and let every one of you be baptized in the name of Jesus Christ for the remission of sins; and you shall receive the gift of the Holy Spirit' " (Acts 2:38). On the subject of baptism see also Colossians 2:11-12, Matthew 28:18-20, and Acts 8:36-39. On the subject of the laying on of hands and the receiving of the Holy Spirit, see Acts 8:14-17 and 1 Timothy 4:14. After one receives the gift of the Holy Spirit, he is a Christian, and must then live a life of spiritual growth, developing God's righteous character with God's help, and overcoming sin. Those who overcome and endure to the end will be saved (Matthew 24:13, Mark 13:13, Matthew 10:22, Revelation 2:11, 3:5). The Church of God encourages its members to spend time on a regular basis in prayer, Bible study, fasting, and meditation as a way of drawing closer to God. Meditation in this sense is basically thinking about God and His laws, learning how to apply spiritual principles to everyday decisions, thinking about the lessons of the Bible, thinking about God's creation, etc., as David did (Psalm 119:97, Psalm 1:2). Prayer is talking to God in prayer, but not repeating memorized prayers (Matthew 6:7). It is obvious that the Day of Pentecost represents the next step in God's plan after repentance, the gift of the Holy Spirit (Acts 2:37-39). The Church keeps Pentecost today to commemorate the gift of the Holy Spirit and the founding of the New Testament Church. But is there a connection between the meaning of the "first fruits" harvest and the coming of the Holy Spirit to the Church? Yes there is, but this will take some explaining. There is truth about this that most traditional churches do not know. Most traditional Christian churches believe that this is the time when God is trying to save all mankind. Some believe that those who do not accept Jesus Christ in this life, in this age, are forever lost. But this is not the case. God has provided a plan for EVERY human that has ever lived to exercise free moral agency to repent, to believe God and Christ, to accept Jesus Christ as savior, and to be converted and be saved. But this plan is being worked out in stages. This six thousand year age of man is not the main spiritual harvest. This is not the time when God is trying to save everyone. Ancient Israel never had access to God's Spirit or to spiritual salvation. They never had the opportunity to accept Jesus Christ as their personal savior. They were never promised eternal life. They were promised physical protection and blessings if they obeyed God's law, but not eternal life. Even since the death and resurrection of Jesus Christ and the founding of the Church of God, most of the billions of people that have lived on this earth never heard the true gospel or had an opportunity for salvation. The fact is, God has allowed Satan to blind and deceive the whole human race for this six thousand year age of man. It is God's purpose to allow man to write the painful lesson in history that Satan's way of "get" and being independent of God's rule, with each person deciding for himself what is right and wrong, is a way that leads to suffering and destruction. Those lessons are being written in history right now, and according to prophecy the suffering of this world is going to increase even more before Christ returns. This is Satan's world right now, not God's. Satan can only do what God allows, and in God's time Satan and his evil influence will be put away, but right now it suits God's purpose to allow Satan to deceive the majority of mankind. There is no "contest" between God and Satan over the salvation of men with God trying to save as many as possible right now and Satan opposing Him. Satan has absolutely NO POWER against God, and can do NOTHING apart from what God allows according to His will. For proof of this, read the first two chapters of the book of Job. Satan could not go one millimeter beyond what God allowed Him to go in attacking Job. If God wanted to open salvation to all mankind at this time, He would do it and Satan has no power to hinder God's efforts in the slightest. God has allowed Satan to blind the minds and hearts of most people to God's truth so they CANNOT understand the truth and be converted. Only the few that God specifically calls and "draws" can be converted at this time. Jesus said, "No one can come to Me unless the Father who sent Me draws him; and I will raise him up at the last day" (John 6:44). Jesus did not try to save everyone, but rather He often spoke in parables, not to make the meaning clear, but to HIDE the meaning from all except those few who were His disciples, whom the Father was drawing to Christ. Notice what Jesus said. "But when He was alone, those around Him with the twelve asked Him about the parable. And He said to them, 'To you it has been given to know the mystery of the kingdom of God; but to those who are outside, all things come in parables, so that "Seeing they may see and not perceive, And hearing they may hear and not understand; Lest they should turn, And their sins be forgiven them" ' " (Mark 4:10-12). Here is a plain statement from Jesus that He spoke in parables to the crowds for the purpose of PREVENTING them from understanding so that they would NOT turn and have their sins forgiven them. It was NOT the Father's will that the crowds repent and receive forgiveness of their sins, AT THAT TIME. But for His disciples, Jesus explained the parables because they were the few that God was calling and drawing to Christ at that time. But not the majority. I do not say that every parable told by Jesus was for the purpose of hiding the meaning. There were some parables Jesus spoke for the purpose of making His teachings clear. Often these had to do with expounding on God's law and teaching right from wrong. For example, the parable of the good Samaritan recorded in Luke 10:25-37 was given to make clear how men should live. It is obvious that the parable was given to make the meaning of God's commandment to love your neighbor as yourself clear to the one who asked Jesus "who is my neighbor?", and it is equally clear that the man got the point, because Jesus said, "You have answered rightly". Nevertheless, Jesus did often speak in parables to hide His meaning from the majority, and when it came to the secrets of the Kingdom of God, these things were revealed only to the disciples, not the crowds. Herbert W. Armstrong taught that from the time before man existed, Lucifer was on a throne of the earth. This is consistent with Isaiah 14:12-14, which says, "How you are fallen from heaven, O Lucifer, son of the morning! How you are cut down to the ground, You who weakened the nations! For you have said in your heart: 'I will ascend into heaven, I will exalt my throne above the stars of God; I will also sit on the mount of the congregation On the farthest sides of the north; I will ascend above the heights of the clouds, I will be like the Most High.' " When Jesus was tempted by Satan, Satan, as ruler over the earth, offered to give his kingdom to Jesus if Jesus would worship him. "Then the devil, taking Him up on a high mountain, showed Him all the kingdoms of the world in a moment of time. And the devil said to Him, 'All this authority I will give You, and their glory; for this has been delivered to me, and I give it to whomever I wish. Therefore, if You will worship before me, all will be Yours.' And Jesus answered and said to him, 'Get behind Me, Satan! For it is written, "You shall worship the Lord your God, and Him only you shall serve" ' " (Luke 4:5-8). Before He was crucified, Jesus said, "I will no longer talk much with you, for the ruler of this world is coming, and he has nothing in Me" (John 14:30). This is Satan's world, his civilization, his system, his way of life that men practice, not God's. But God is calling a few now into His true Church to learn and live a different way of life. Eventually, God will remove Satan and make salvation available to every human that has ever lived. That will be the great spiritual harvest. I will go into more detail about that later. But right now, in this age of man, is the smaller spiritual harvest of the few that God is saving now. Christians in this age are called "firstfruits" (James 1:18, Revelation 14:4). These are the firstfruits, the early harvest, as pictured in the Old Testament Feast of Weeks or Feast of Firstfruits, and this is the connection between the coming of the Holy Spirit on the Day of Pentecost in the book of Acts, and the same day picturing the early summer harvest in the Old Testament. And this is another valuable lesson God uses His holy days to teach us. Jesus Christ is also called the firstfruits in 1 Corinthians 15:23, and he is pictured in the wave sheaf offering in Leviticus 23:9-11. Christ is the first of the firstfruits, and after Him are those called and drawn by God to Christ to be saved in this age. But the majority of mankind is not now being offered salvation. God is only saving a few now. But why? This will become clear as we go through the rest of God's holy days.
