A period cannot be a point in time - it is the time elapsed between two points in time. Period does not imply any form of delimiting event or circumstance - it just refers to time itself. 26 days or 11 minutes is a period. Stage and phase both refer to some sort of process. When referring to time, they imply a beginning and an end but also some process outside that period of which the stage or phase forms part.
