The solar calendar version Gregorian Calendar (aka Christian calendar which is different from Islamic calendar) had a discrepancy. The Christians bishops were aware of the problem but had no solution. A Muslim scholar Omar Khayyam measured the length of the year too accurately in 10th Century! His length - 365.242198581 days - was an accuracy which exceeds the very gradual slowing of the rotation of the earth. It has since been discovered that the number changes in the 6th decimal place over a person's lifetime. For comparison of Khayyam's accuracy, the length of one year at the end of the 19th century was 365.242196 days, and today it is 365.242190. However he was not only an astronomer but also a well-known mathematician, philosopher, and poet. I read a few of his Rubaiyat during high school. One stanza that i could not forget and i just love it is:

There was a Door to which I found no Key:
There was a Veil through which I could not see:
Some little Talk awhile of Me and Thee
There seemed -- and then no more of Thee and Me.
