This is usually memorized as 365 for ordinary years. IF the two terminal numbers of the year number are divisible by 4, THEN it is a Leap Year, and has 366 days. e.g. the year 2016 is so, and is a leap year. AND IF the two terminal numbers are 00, THEN IF the first pair of numbers is divisible by 4 then it it is a leap year. Thus 1600 and 2000 were leap years, but 1700, 1800 and 1900 were not.

It's possible that diamonds were discovered in India as long ago as 6,000 years. Without documentation, it might be difficult to settle on a precise year in which diamonds were first mined. Initially, it's understandable that diamonds were found far from their point of origin, having been washed into riverbeds by water running over the diamond pipe.
