Question

1. what do we do with the extra 0.24 days each year upon the completion of earths revolution?

we move our clocks back an hour in the fall and ahead an hour in the spring.
nothing is done with them, and our yearly calendar always has 365 days.
every year on new years day, we get an extra 4 hours added to our day.
every 4 years they are put together, and we add one day to our yearly calendar.

Explanation:

The Earth's revolution around the Sun takes approximately 365.24 days. The extra 0.24 days each year accumulate. Over 4 years, \(0.24\times4 = 0.96\approx1\) day. So, every 4 years (leap year), an extra day (February 29) is added to the calendar. Moving clocks back/forward (Day - light Saving Time) is not related to this 0.24 - day accumulation. A year always having 365 days ignores the extra time. Adding 4 hours on New Year’s Day is not a standard practice.

Answer:

Every 4 years they are put together, and we add one day to our yearly calendar.
