This year we're going to experience four unusual dates: 1/1/11, 1/11/11, 11/1/11, 11/11/11. On top of that, this year, July has 5 Fridays, 5 Saturdays and 5 Sundays. This happens once every 823 years.
And here's a neat trick that will work for everyone: Take the last two digits of the year in which you were born - now add the age you will be this year. The results will be 111 for everyone in whole world if you're born in the "1900's". If you were born in the "2000's" then the number is only 11, i.e. 2000 + 11 years old.
