"Our planet rotates in full orbit around the sun, in a year it lasts 365 days, 5 hours, 48 minutes and 56 seconds, not 365.
Emperor Julius Caesar proposed the leap year. If we count those 365 days every year, those 5 hours that we will have to recover will be missing.
For three years we counted those 365 and in the fourth we recovered the day that is missing, the 29 days that has February, the leap year.
If we did not add a full day every four years, the seasons would end up unpacked from the calendar, so that after about 700 years, in the northern hemisphere Christmas would fall in the middle of summer.
Scientifically and mathematically, it takes a day in time, We know that God is the creator of the universe and everything there is, and although some scientists, mathematicians and philosophers, have not been able to deny the bible nor its veracity. Then let's see what the Bible says about that missing day.
Then spake Joshua to Jehovah in the day when Jehovah delivered up the Amorites before the children of Israel; and he said in the sight of Israel,
Sun, [a]stand thou still upon Gibeon;
And thou, Moon, in the valley of Aijalon.
And the sun stood still, and the moon stayed,
Until the nation had avenged themselves of their enemies.
Is not this written in the book of Jashar? And the sun stayed in the midst of heaven, and hasted not to go down about a whole day.
Joshua 10:12-13 American Standard Version
