## People born in 1978 are Generation X, which Pew Research Center dates from 1965 to 1980.

1978 is the 14th of the 16 birth years in that span. The range comes from [Pew Research Center](https://www.pewresearch.org/short-reads/2019/01/17/where-millennials-end-and-generation-z-begins/).

_Figure: The birth years 1930 to 2025 in five bands: before 1946, Baby Boomers 1946 to 1964, Generation X 1965 to 1980, Millennials 1981 to 1996, and Generation Z from 1997. 1978 is marked in the Gen X band._

## Here are the years in which someone born in 1978 reaches each milestone age.

A birthday in 1978 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.

## 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 Monday, October 26, 2026, counted in US Eastern time, so a birthday on or before October 26 has passed (you are 48) and one from October 27 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.

When can I get full Social Security retirement benefits if I was born in 1978?

The SSA table gives a full retirement age of 67 for people born in 1978, which you reach in 2045. The earliest age retirement benefits can start is 62, which you reach in 2040.
