Most people know that the Earth takes 365.25 rotations (called "days") to complete one revolution around the sun (called 1 "year"). More accurately (according to wikipedia) the Earth takes 365.256363004 days to revolve.

My quick math (which could be horribly mistaken) leads me to believe that we are going to need to have an extra leap year once every ~160 years to account for the extra 0.006363004 "days". Otherwise, the Gregorian calendar will start becoming offset from the seasons.

Am I mistaken about this concept or the math? Are there plans for a Feb 30th to occur sometime soon?

I think the official policy is that its too small of a difference for anyone to care about.

If that does happen though with delayed seasons or anything, we'll probably do what the church did in 1582 and skip a random 10 calendar days to achieve the normal calendar's astronomical balance.

So every 160 years it gets out of date by 1 day.
Now the question is, has it been always like this?
Do they know this since Jesus times? Or when did they find out about this?
etc..

Im sure theres entities taking care of all of this shit, you got more important stuff to worry about your life than with the job of others right?

Thank you for proving the OP thinks hes Einstein.

Also interesting to note is that if a year is a multiple of 100 but NOT a multiple of 400, we don't have a leap year. 1700, 1800, and 1900 were not leap years. 2000 was.
