The Scriptures teach that there are seven annual feasts and holy days which were ordained by God to be observed as special commanded convocations. These feasts and holy days portray God’s plan of salvation for mankind. The observance of these holy convocations is a sign between God and His people. God’s annual feasts and holy days were observed by His people during the Old Testament times. In the New Testament, we find that Jesus Christ’s entire ministry was centered around the spiritual meaning of these holy days. The New Testament apostolic Church faithfully observed these annual feasts and holy days. The Scriptures reveal that they will be observed by all mankind after the return of Jesus Christ.
As the holy days are annual Sabbath days, they may fall on any day of the week (except Pentecost, which always falls on a Sunday). When a holy day falls on a weekly Sabbath, the special observance of the annual holy day takes precedence. God’s feasts and holy days are to be observed from sunset to sunset in accordance with the Calculated Hebrew Calendar as preserved by the Levitical Jews. The seven annual feasts and holy days are as follows:
