1967
In 2010 their age will be twenty-four years.
1914
As today is 1st January 2010 and you are 26 years old you were born in the year 1983.
Their birthday in 2010 would put them at 19 years old.
The perfect age varies from person to person, regardless of what year they were born in. It will start when it is supposed to, and end when it it supposed to.
You would be (as of 2014, when this question was answered) 17 years old.Age Now = Year Now - Year of Birth (if the person has had their birthday this year, and one less if they have not).
The year they were born
The year they were born
Age Now = Year Now - Year of Birth (if the person has had their birthday this year, and one less if they have not).
Subtract the year they were born from the current year.
If it's 2014 and you're 36 years old, you would have been born in 1978. You can find this answer by taking the current year and subtracting the age, which will give you the birth year. Of course, depending on when the person's birthday is your answer could be off by a year.
current year - your age = birth year
