The Social Security age of retirement used to be straightforward and the same for everyone. Not anymore.
From the first Social Security Act back in 1935 through 1983, the full Social Security age of retirement was 65. Then things got a little confusing. Due to the 1983 Amendments to the Social Security Act, the full retirement age began to gradually increase from age 65 to 67. However, it took 22-years to adjust! It slowly increased from 65 to 66, stayed at 66 for 11 years, and then began to move slowly to 67.
Whew! No wonder everyone is confused about their Social Security age of retirement.
Thankfully, these changes have mostly worked themselves through the system and now the full retirement age is based on your year of birth.
