Logics tells us that time should be either linear, cyclical or circular. Either it begins and ends. Or it repeats itself endlessly. Or it does not begin nor end but is a loop. These 3 states are mutually exclusive. However, our individual experience tells us something different.
Our experience tells us that time can be linear and cyclical and circular. Time does begin and end every year, from the first of January to the 31st of December. A measurable unique timeline, i.e., time is linear. Simultaneously, time moves from winter to spring, summer, then fall, and then back into winter again. A chain of events, i.e. cyclical time. On top of this, we also experience time as being circular, as in, the 1st of January follows again after the 31th of December. An endless loop.
