The notion of 'cyclical' time confuses processes with time. Time is the dimension along which processes unfold. A year is the temporal duration of a cyclical process: one revolution of the Earth around the Sun. A day labels the temporal duration of a cyclical process: one rotation of the Earth on its axis. Seconds, minutes, hours, days, months, seasons and years label time intervals of cyclical processes. It is not time that is cyclical but the process that unfolds in time.
