The Accrue From date is used to determine when the accrual calculation starts for a particular accrual rule. For example, if a rule starts on April 1, 2014, time recorded prior to this date will not be included in the calculation for available hours left (displayed in the Accrual Information box).
The default Accrue From Date for the rule is the day it was assigned to an employee. For example, if a rule is assigned to Juan on June 1, the Accrue From Date for Juan will be June 1. If the same rule is assigned to Mary on July 15, the Accrue From Date for Mary will be July 15.
