HOW TO MEASURE TIME WITHOUT A CLOCK

Clocks divide the day into hours, minutes and seconds. But, would it be possible to calculate time without a clock? Yes, based on the change-interval duality. The repetition of a process with constant duration is taken. All processes have a start, an end and an evolution. An example of this process is a musical song. Considering the lyrics and notes of a song you can determine the specific moment in the evolution of the song. The duration of the song is the unit of time. Although the use of a song is not useful, at least we know that we can estimate time without using a clock.
