The calendar year 1945
1945 was a common year: 365 days, with 28 days in February. It opened on a Monday.
1945 is The Silent Generation
Births from 1928 to 1945 fall inside The Silent Generation, putting 1945 18 of 18 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.

| 65 | 2010 | Medicare eligibility begins |
| 66 | 2011 | Full Social Security retirement age (66) |

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.
