Subtract 20-2017. Easy you should be able to figure that out at 20 years old.
If you are 20 in 2017, then you were born in 1997.
This year is 2017, so 2017-20 = 1997
1997 was 20 years before 2017.
A person turning 20 in 2014 was born in 1994.
2001 is the birth year for 20 yr olds the year of 2021!
As of January 2010 the year of birth would be 1989 and will turn 21 on April 1st.
If a person turns 21 next year, they were born in the year 2002. This is because turning 21 next year means they will be 20 years old this year. Therefore, subtracting 20 from the current year gives us their birth year.
People born in 1999 will always be one year older than the current year, making them 18 in 2017 and 19 in 2018.
The next presidential term will start on 17 January 2017.
At the moment she is 20. She'll turn 21 on December 22. She is born in the year 1989.
I think this person is asking what the last date that a sitting president is in office and if so, it is January 20 of the year following an election that he did not win.
You would be 11 or 12 yeah
