What year was I born if I'm 46?
1979 or 1980
Anyone who is 46 today, Thursday, September 24, 2026, was born between Tuesday, September 25, 1979 and Wednesday, September 24, 1980. The boundary falls in the middle of the year, so the answer spans two of them.
- Earliest birth date
- September 25, 1979
- Latest birth date
- September 24, 1980
- Birth years
- 1979 or 1980
- Age today
- 46
Which year, exactly
Someone born on Wednesday, September 24, 1980 turns 46 today. Someone born a day later, on Thursday, September 25, 1980, is still 45 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 46 today, a date of birth has to fall on or after Tuesday, September 25, 1979 and on or before Wednesday, September 24, 1980.
That window contains 29 February 1980, so some people who are 46 today were born on a date that only comes round every four years — 46 years old with 11 birthdays behind them rather than 46. The next 29 February is when they have another.
