-minu was born on June 16, 1947.
The subtraction is 71. A person that was born in 1938 and has already had his birthday (January or February) is 71 yrs old. If he didn't have a birthday yet he is 70 until his birthday, then he's 71.
Statistically speaking, you are going to find people who have the same birthday. For example, in a classroom of 30 students, you have a 40% chance to have the same birthday as someone else in the classroom.
2011 minus 1995 = 16. You would be 16 unless your birthday is after today, then you would still be 15.
20 years old in July 2010. (2010 minus 1990 = 20)
2014 minus 1938 is 76. If you were born in 1938 and had a birthday this year then you would be 76 years old.
To find out how old you are you need to subtract 1990 from 2017 2017 minus 1990 = 27
