In 1974, a quiet and ill-advised change was made to how Pentecost is counted, inadvertently aligning the toil of harvesting with a high holy day Sabbath.

According to the Scripture, the count to Pentecost must begin on the day after the Sabbath in the Days of Unleavened Bread, even in 'anomalous' years.

The Jews establishes a fixed date for Shavuot in contradiction to the instruction for counting to Pentecost. This is part of the leavening of the Pharisees.
