What year was I born if I'm 70?
1955 or 1956
Anyone who is 70 today, Thursday, September 24, 2026, was born between Sunday, September 25, 1955 and Monday, September 24, 1956. The boundary falls in the middle of the year, so the answer spans two of them.
- Earliest birth date
- September 25, 1955
- Latest birth date
- September 24, 1956
- Birth years
- 1955 or 1956
- Age today
- 70
Which year, exactly
Someone born on Monday, September 24, 1956 turns 70 today. Someone born a day later, on Tuesday, September 25, 1956, is still 69 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 70 today, a date of birth has to fall on or after Sunday, September 25, 1955 and on or before Monday, September 24, 1956.
That window contains 29 February 1956, so some people who are 70 today were born on a date that only comes round every four years — 70 years old with 17 birthdays behind them rather than 70. The next 29 February is when they have another.
