Lillius was not a cleric of any sort let alone a Jesuit. His scheme was examined, contemplated and finally recommended by a committee that met irregularly over a period of more than ten years. The exact composition of this committee is not known, as it varied over the years, but nine members signed the final recommendation to the Pope of whom only one, the least significant member Christoph Clavius, was a Jesuit. Following the introduction of the calendar by the Catholic Church Clavius, at the request of the Pope, took over the defence of the new system of time measurement against its many critics, writing six books on the subject over the next thirty odd years, thus becoming closely associated with the calendar although he did not create it.
