This year will be the year when the date of the 11th of November 2011 will be 11/11/11. So, what year were *you* born? 1993 (93), maybe? Or 1981 (81)? Or maybe 1960 (60)? Whatever your birthdate, when you have your birthday, this year - as long as you are born in the 20th century - your current age plused with the last two digits of your birthdate will amount to 111. But only this year - not last year, and not next year. Next time this will happen will be the year 2111.
Coincidence?
no. it is just a simple value that is inevitable given the inputs.
the same thing can be said for every year.
last century, if this process was performed, then it would not have seemed very interesting.
example: in 1980, everyone's answer would have been 80. (if you were born in 1950 ('50), then you would have been 30 in 1980. 30+50=80......wow... if your were born in '40, then you would be 40 in 1980 ('80) and 40+40=80....wow..). what ever the year you were born plus your age "this year" is obviously going to be "this year". it is the same as saying "this year minus my age will be the year in which i was born"
however, because the century is ignored in your example, there is going to be 100 (years) added to the value of the result of everyone born last century, and nothing added to the result for people born this century. that is because there is no reset to zero at he turn of the century in reality as there is in years represented by only the last 2 digits (as in your example).
example: "a 2 year old in 2001 was born in 1999" is reduced to "a 2 year old in '01 was born in '99" when the century is ignored.
if '99 became '100 instead of '00, then the 100 year value increase would not occur because all the values are absolute, so 99+2=101 (not -1+2='01)
whatever.
