The letter J does not appear anywhere on the periodic table of the elements
In 2012, December has 5 Saturdays, and 5 Sundays,and 5 Mondays. ( TRUE.... I checked it ! )
This apparently happens once every 823 years! ( Meaning in 823 years December will have 5 Saturdays 5 Sundays 5 Mondays again and not till then)
I updated this due to everybody reading into it wrong sorry.
