What year was I born if I'm 99?

1926 or 1927

Anyone who is 99 today, Thursday, September 24, 2026, was born between Saturday, September 25, 1926 and Saturday, September 24, 1927. The boundary falls in the middle of the year, so the answer spans two of them.

Which year, exactly

Someone born on Saturday, September 24, 1927 turns 99 today. Someone born a day later, on Sunday, September 25, 1927, is still 98 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 99 today, a date of birth has to fall on or after Saturday, September 25, 1926 and on or before Saturday, September 24, 1927.

There is no 29 February in that window, so everyone who is 99 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.
