Every day is Sunday. > > What day it it? It's sunday. > > Clocks count events of supposedly even frequency. There are many different types of clocks. The most simple clock counts only years. A little more advanced is a calendar, which is used to count days. But better clocks do exist, which could count much shorter intervals. But they all have in common, that they are essentially counters, which multiply the base frequency with that number and 'compute' some sort of human readable time values. Time is now, what makes these events flow in equal intervals. That is actually hard to measure, because if time would start to flow faster or slower, our clocks wouldn't notice that, because they depend on time, however fast time flows. TH
