What year was I born if I'm 10?
2015 or 2016
Anyone who is 10 today, Friday, November 13, 2026, was born between Saturday, November 14, 2015 and Sunday, November 13, 2016. The boundary falls in the middle of the year, so the answer spans two of them.
- Earliest birth date
- November 14, 2015
- Latest birth date
- November 13, 2016
- Birth years
- 2015 or 2016
- Age today
- 10
Which year, exactly
Someone born on Sunday, November 13, 2016 turns 10 today. Someone born a day later, on Monday, November 14, 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 Saturday, November 14, 2015 and on or before Sunday, November 13, 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.
