What year was I born if I'm 90?
1935 or 1936
Anyone who is 90 today, Friday, November 13, 2026, was born between Thursday, November 14, 1935 and Friday, November 13, 1936. The boundary falls in the middle of the year, so the answer spans two of them.
- Earliest birth date
- November 14, 1935
- Latest birth date
- November 13, 1936
- Birth years
- 1935 or 1936
- Age today
- 90
Which year, exactly
Someone born on Friday, November 13, 1936 turns 90 today. Someone born a day later, on Saturday, November 14, 1936, is still 89 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 90 today, a date of birth has to fall on or after Thursday, November 14, 1935 and on or before Friday, November 13, 1936.
That window contains 29 February 1936, so some people who are 90 today were born on a date that only comes round every four years — 90 years old with 22 birthdays behind them rather than 90. The next 29 February is when they have another.
