Age by birth year
Here are four questions about being born in 1978, answered.
How old am I if I was born in 1978?
In 2026 you are 48 if your birthday has already passed this year and 47 if it has not. Today is Tuesday, November 3, 2026, counted in US Eastern time, so a birthday on or before November 3 has passed (you are 48) and one from November 4 on is still to come (you are 47).
How old will I be on December 31, 2026 if I was born in 1978?
You will be 48. Every birthday of 2026 has happened by December 31, so everyone born in 1978 is 48 on the last day of 2026, and 49 on December 31, 2027.
What year was I born if I am 48 in 2026?
You were born in 1978 if your birthday has already passed this year, or in 1977 if it has not come round yet. 2026 minus 1978 is 48, and someone born in 1977 is still 48 until their birthday this year.
