The calendar year 1975
1975 was a common year: 365 days, with 28 days in February. It opened on a Wednesday.
1975 is Generation X
Births from 1965 to 1980 fall inside Generation X, putting 1975 11 of 16 years into the cohort.
Those cut-offs are the Pew Research Center definitions, which are the ones most US reporting follows. Pew itself notes that generational boundaries are a convention, not a hard science.
Milestone years for someone born in 1975

|---|---|---|
| 16 | 1991 | Old enough to drive in most states |
| 18 | 1993 | Legal adult — eligible to vote |
| 21 | 1996 | Legal drinking age nationwide |
| 25 | 2000 | Most car-rental young-driver surcharges end |
| 30 | 2005 | Turns 30 |
| 40 | 2015 | Turns 40 |
| 50 | 2025 | Turns 50 |
| 62 | 2037 → | Earliest age to claim Social Security retirement benefits |
| 65 | 2040 → | Medicare eligibility begins |
| 67 | 2042 → | Full Social Security retirement age (67) |
| 70 | 2045 → | Delayed retirement credits stop accruing |
Full retirement age by year of birth follows the Social Security Administration schedule set by the 1983 amendments. Driving, drinking, and rental thresholds are the common US rules and vary by state and company.
