A Brief Overview of The Apostolic Festivals
Throughout the New Testament writings we see the Apostles celebrating and teaching the faith from the original Biblical festivals including Passover, Firstfruits, and Pentecost. At no point do we read that they adopted a different calendar or set of festivals.
Overview & Calculation
Below are the biblical festivals as calculated by the CACI Apostolic Council. To arrive at these dates, we use the "first light" of the New Moon to find the 1st day of the new month. After finding the 1st day, we count to the day of the month recorded in the Torah (14th, 15th, 10th, Etc).
The dates promoted by Rabbinic Judaism are no longer calculated according to Torah. They are often 24 to 48 hours off in an attempt to align more seamlessly to the western calendar. The result is, the festivals often will not reflect the correct placement of the Moon as they do when calculated according to scripture. To address this, rabbinic tradition has extended many celebrations by adding additional days to the festival.
It is important to note the dates below may be altered slightly if the moon is actually sighted 24 hours before or after the expected date. Also, the dates may shift by a complete month in the event that the barley in Israel is not green in time for Aviv. This is not unusual, occurring every few years.
All dates are calculated according to the recognized Covenant Calendar of the CACI Ecclesiastical Body. Observance begins at sunset on the date specified for the evening preceding the Holy Day. Please consult your local congregational calendar for precise service times and location information.
