What year was I born if I'm 48?
1977 or 1978
Anyone who is 48 today, Friday, November 13, 2026, was born between Monday, November 14, 1977 and Monday, November 13, 1978. The boundary falls in the middle of the year, so the answer spans two of them.
- Earliest birth date
- November 14, 1977
- Latest birth date
- November 13, 1978
- Birth years
- 1977 or 1978
- Age today
- 48
Which year, exactly
Someone born on Monday, November 13, 1978 turns 48 today. Someone born a day later, on Tuesday, November 14, 1978, is still 47 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 48 today, a date of birth has to fall on or after Monday, November 14, 1977 and on or before Monday, November 13, 1978.
There is no 29 February in that window, so everyone who is 48 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.
