You implemented an incremental absence plan with a waiting period of three months and a vesting rule of three months. The leave year runs from 1st of January. There is a flat accrual rate of five hours per month.

If an employee was hired on 01 April, which month should you run the process for in order for this employee to have 20 hours available in their absence entitlement?
