How old are you if you were born in 2015?
The year on its own only narrows the answer to two numbers. Which one applies depends on whether this year’s birthday has already come around.

The calendar year 2015
2015 was a common year: 365 days, with 28 days in February. It opened on a Thursday.
2015 is Generation Alpha
Births from 2013 to 2024 fall inside Generation Alpha, putting 2015 3 of 12 years into the cohort.
Pew Research Center has not defined this cohort, so the years above reflect common usage rather than a single research definition. Treat them as a label, not a measurement.
Milestone years for someone born in 2015
Each row is a US age threshold and the calendar year a 2015 birth reaches it. Exact dates depend on the birthday itself.
| Age | Year | What happens |
|---|---|---|
| 16 | 2031 → | Old enough to drive in most states |
| 18 | 2033 → | Legal adult — eligible to vote |
| 21 | 2036 → | Legal drinking age nationwide |
| 25 | 2040 → | Most car-rental young-driver surcharges end |
| 30 | 2045 → | Turns 30 |
| 40 | 2055 → | Turns 40 |
| 50 | 2065 → | Turns 50 |
| 62 | 2077 → | Earliest age to claim Social Security retirement benefits |
| 65 | 2080 → | Medicare eligibility begins |
| 67 | 2082 → | Full Social Security retirement age (67) |

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.
