What year was I born if I'm 77?
1948 or 1949
Anyone who is 77 today, Thursday, September 24, 2026, was born between Saturday, September 25, 1948 and Saturday, September 24, 1949. The boundary falls in the middle of the year, so the answer spans two of them.
- Earliest birth date
- September 25, 1948
- Latest birth date
- September 24, 1949
- Birth years
- 1948 or 1949
- Age today
- 77
Which year, exactly
Someone born on Saturday, September 24, 1949 turns 77 today. Someone born a day later, on Sunday, September 25, 1949, is still 76 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 77 today, a date of birth has to fall on or after Saturday, September 25, 1948 and on or before Saturday, September 24, 1949.
There is no 29 February in that window, so everyone who is 77 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.
