What year was I born if I'm 80?
1945 or 1946
Anyone who is 80 today, Thursday, September 24, 2026, was born between Tuesday, September 25, 1945 and Tuesday, September 24, 1946. The boundary falls in the middle of the year, so the answer spans two of them.
- Earliest birth date
- September 25, 1945
- Latest birth date
- September 24, 1946
- Birth years
- 1945 or 1946
- Age today
- 80
Which year, exactly
Someone born on Tuesday, September 24, 1946 turns 80 today. Someone born a day later, on Wednesday, September 25, 1946, is still 79 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 80 today, a date of birth has to fall on or after Tuesday, September 25, 1945 and on or before Tuesday, September 24, 1946.
There is no 29 February in that window, so everyone who is 80 today has had a birthday every year since they were born. Twenty-five of the hundred ages on this site do span a leap day; this is not one of them.
