To make up for this lost time, we of course have added the idea of a "leap year" in which every 4 years we add an extra day. But if you do the math, that "leap year" does not fully account for every last second & as time continues to add... Those seconds become minutes, hours, days.... And of course, what about all the years before the calender included a "leap year"....
Err - do you not know why we have a leap year?
We say there are 365 days in the year and by this we mean that it takes the earth 365 days to make its annual trip around the sun. Actually, though, it takes the earth 365-1/4 days to make this trip. This means that every year we gain one-fourth of a day and every four years we gain one full day.
If we did nothing about this, our calendar would move backward one full day every four years relative to our seasons. To keep this from happening, we capture the extra day every four years and put it into our smallest month, February.
Something like that.
