What year was I born if I'm 10?

2015 or 2016

Anyone who is 10 today, Thursday, September 24, 2026, was born between Friday, September 25, 2015 and Saturday, September 24, 2016. The boundary falls in the middle of the year, so the answer spans two of them.

Which year, exactly

Someone born on Saturday, September 24, 2016 turns 10 today. Someone born a day later, on Sunday, September 25, 2016, is still 9 until tomorrow. That is why “what year” has two answers rather than one, and why a birth date rather than a year is what settles it.

Read the other way round: to be exactly 10 today, a date of birth has to fall on or after Friday, September 25, 2015 and on or before Saturday, September 24, 2016.

That window contains 29 February 2016, so some people who are 10 today were born on a date that only comes round every four years — 10 years old with 2 birthdays behind them rather than 10. The next 29 February is when they have another.
