What year was I born if I'm 55?
1970 or 1971
Anyone who is 55 today, Friday, November 13, 2026, was born between Saturday, November 14, 1970 and Saturday, November 13, 1971. The boundary falls in the middle of the year, so the answer spans two of them.
- Earliest birth date
- November 14, 1970
- Latest birth date
- November 13, 1971
- Birth years
- 1970 or 1971
- Age today
- 55
Which year, exactly
Someone born on Saturday, November 13, 1971 turns 55 today. Someone born a day later, on Sunday, November 14, 1971, is still 54 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 55 today, a date of birth has to fall on or after Saturday, November 14, 1970 and on or before Saturday, November 13, 1971.
There is no 29 February in that window, so everyone who is 55 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.
