What year was I born if I'm 78?
1947 or 1948
Anyone who is 78 today, Friday, November 13, 2026, was born between Friday, November 14, 1947 and Saturday, November 13, 1948. The boundary falls in the middle of the year, so the answer spans two of them.
- Earliest birth date
- November 14, 1947
- Latest birth date
- November 13, 1948
- Birth years
- 1947 or 1948
- Age today
- 78
Which year, exactly
Someone born on Saturday, November 13, 1948 turns 78 today. Someone born a day later, on Sunday, November 14, 1948, is still 77 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 78 today, a date of birth has to fall on or after Friday, November 14, 1947 and on or before Saturday, November 13, 1948.
That window contains 29 February 1948, so some people who are 78 today were born on a date that only comes round every four years — 78 years old with 19 birthdays behind them rather than 78. The next 29 February is when they have another.
