2011 is a very special year

Did you know that the year 2011 is a very special year?
This phenomenon repeats only once every 823 years.
Firstly, the month of October has 5 Mondays, 5 Saturdays and 5 Sundays
Then we have the dates of 01/01/11, 1/11/11 then the then the 11/11/11 (if you use it in date/month/year order)
And what is even more interesting if you ad up your birth year and the years of age you become this year the result is 111
For example, you're born in 1970 then 70 plus 41 equals 111
This number is the same for all people this year.
Try it once with the data of your friends, it is always the 111 as a result.
