What is the definition of time?
One of the earlier views was presented by the ancient Greek philosopher Aristotle (384-322 BC), who defined time as "a number of movement in respect of the before and after." Essentially, Aristotle's view of time defined it as a measurement of change requiring the existence of some kind of motion or change. He also believed that time was infinite and continuous, and that the universe always did, and always will exist. Interestingly, he was also one of, if not the first person to frame the idea that time existing of two different kinds of non-existence, makes time existing at all, questionable. Aristotle's view is solely one amongst many in the discussion of time, the most controversial of which began with Sir Isaac Newton, and Gottfried Leibniz.
What does Leibniz believe about time?
Contrary to Newton's assertions, Leibniz believed that time only makes sense in the presence of objects with which it can interact.

It is simply the way in which humans subjectively perceive and sequence the objects, events, and experiences accumulated throughout their lifetimes.
Which calendar system was developed by Pope Gregory XIII?
