How old are you if you were born in 2000?
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.
Find your birth month below. Months that share a row with two ages are the ones the birthday falls inside right now.

The calendar year 2000
2000 was a leap year: 366 days, with 29 days in February. It opened on a Saturday.
2000 is Generation Z
Births from 1997 to 2012 fall inside Generation Z, putting 2000 4 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 2000
Each row is a US age threshold and the calendar year a 2000 birth reaches it. Exact dates depend on the birthday itself.
| Age | Year | What happens |
|---|---|---|
| 16 | 2016 | Old enough to drive in most states |
| 18 | 2018 | Legal adult — eligible to vote |
| 21 | 2021 | Legal drinking age nationwide |
| 25 | 2025 | Most car-rental young-driver surcharges end |
| 30 | 2030 → | Turns 30 |
| 40 | 2040 → | Turns 40 |
| 50 | 2050 → | Turns 50 |
| 62 | 2062 → | Earliest age to claim Social Security retirement benefits |
| 65 | 2065 → | Medicare eligibility begins |
| 67 | 2067 → | Full Social Security retirement age (67) |
| 70 | 2070 → | 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.
