Yet, in the traditional Hebrew calendar, there have been postponements made because of human traditions: (a) one guarding against Rosh Hoshana falling on Wednesday or Friday because it will cause Yom Kippur to fall on Friday or Sunday and require two days of prohibition against food preparation and (b) another guarding against the celebration of Hoshanah Rabbah (a traditional Jewish observance during Sukkoth -- like Purim and Chanukkah) falling on the weekly Sabbath during the Feast of Tabernacles (Sukkoth) because it would require work to be done in gathering the willow twigs needed for beating on the ground during the ceremony (A Book of Jewish Concepts, Philip Birnbaum; New York: Hebrew Publishing Co., 1964). These postponements can move back the normal observance of God's Holy Days by as much as two days. In the years when there are no postponements, the TSDCA calendar coincides with the traditional Hebrew calendar and former WCG churches. In the years when there are postponements, TSDCA observes God's Holy Days 1-2 days earlier than others.
Second, if Passover is observed on the weekly Sabbath, TSDCA does not begin its count of 50 days toward Pentecost on the Sunday that immediately follows. We begin the count just like we do in all other years: From the Sabbath within the Feast of Unleavened Bread -- even if it is the last day of the Feast of Unleavened Bread. During those years, TSDCA will observe Pentecost a week later than the others. Mr. Armstrong admitted in his writings that such a determination depended on who controlled the Temple -- Sadducees or Pharisees. TSDCA reasons that Passover might be a day of unleavened bread, but it is a separate observance from the Feast of Unleavened Bread. Therefore, we follow the instructions as given in Leviticus 23:6-16.
Because there is no precise, specific instruction in scripture about how to determine God's Holy Days (for example: how one determines the new moon), TSDCA does not claim to have the exact formula required by God. We do not rail against those who do not comply with our method. We simply live by the light that we believe to be correct. Part of that light makes no room for human traditions.
