People born in 1977 are Generation X, which Pew Research Center dates from 1965 to 1980.

1977 is the 13th of the 16 birth years in that span. The range comes from Pew Research Center.

Here are the years in which someone born in 1977 reaches each milestone age.

A birthday in 1977 plus the age gives the year, and the birthday itself decides whether it is the earlier or the later of two years where the table shows both.

The age calculator gives your exact age from a full birth date, with the days to your next birthday, and the days between dates calculator counts the gap between any two dates.

Here are four questions about being born in 1977, answered.

How old am I if I was born in 1977?
In 2026 you are 49 if your birthday has already passed this year and 48 if it has not. Today is Monday, October 26, 2026, counted in US Eastern time, so a birthday on or before October 26 has passed (you are 49) and one from October 27 on is still to come (you are 48).
How old will I be on December 31, 2026 if I was born in 1977?
You will be 49. Every birthday of 2026 has happened by December 31, so everyone born in 1977 is 49 on the last day of 2026, and 50 on December 31, 2027.
What year was I born if I am 49 in 2026?
You were born in 1977 if your birthday has already passed this year, or in 1976 if it has not come round yet. 2026 minus 1977 is 49, and someone born in 1976 is still 49 until their birthday this year.
When can I get full Social Security retirement benefits if I was born in 1977?
The SSA table gives a full retirement age of 67 for people born in 1977, which you reach in 2044. The earliest age retirement benefits can start is 62, which you reach in 2039.
