Time is a human construct. From planck time to supereons. They are relative units of measure. Likewise, hours and years are something humans created to keep track/record, predict and categorize based on Earth’s orbit and its revolution around the Sun. There is not a static number of hours in a year, for instance, if you consider leap years, they are 24 hours longer. So approximately 8784 hours in a leap year on Earth. If we lived on Mars, we would experience 16,500 hours in a year.
