What year was I born if I'm 20?
2005 or 2006
Anyone who is 20 today, Friday, November 13, 2026, was born between Monday, November 14, 2005 and Monday, November 13, 2006. The boundary falls in the middle of the year, so the answer spans two of them.
- Earliest birth date
- November 14, 2005
- Latest birth date
- November 13, 2006
- Birth years
- 2005 or 2006
- Age today
- 20
Which year, exactly
Someone born on Monday, November 13, 2006 turns 20 today. Someone born a day later, on Tuesday, November 14, 2006, is still 19 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 20 today, a date of birth has to fall on or after Monday, November 14, 2005 and on or before Monday, November 13, 2006.
There is no 29 February in that window, so everyone who is 20 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.
