If you were born today what age would you be in 2045?

Answer 1

36 years old (2045-2009) A more pedantic or detailed answer is as follows: Today is 13 August. Assume this is the date of posting the question, though that does not alter the answer substantially. From 1 January 2045 to 12 August 2045 you would consider yourself to be 35 years old. Your 36th birthday would fall on 13 August 2045 and from that date to the end of the year you would consider yourself 36.

Answer 2

If you were born today, you would be considered 0 years old in 2021. In 2045, you would be 24 years old. This is because you would have lived through 24 full years from your birth year to 2045.
