Here are four questions about being born in 1940, answered.
- How old am I if I was born in 1940?
- In 2026 you are 86 if your birthday has already passed this year and 85 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 86) and one from October 27 on is still to come (you are 85).
- How old will I be on December 31, 2026 if I was born in 1940?
- You will be 86. Every birthday of 2026 has happened by December 31, so everyone born in 1940 is 86 on the last day of 2026, and 87 on December 31, 2027.
- What year was I born if I am 86 in 2026?
- You were born in 1940 if your birthday has already passed this year, or in 1939 if it has not come round yet. 2026 minus 1940 is 86, and someone born in 1939 is still 86 until their birthday this year.
- When can I get full Social Security retirement benefits if I was born in 1940?
- The SSA table gives a full retirement age of 65 and 6 months for people born in 1940, which you reach in 2005 or 2006. The earliest age retirement benefits can start is 62, which you reach in 2002.
