Everyone born in 2025 turns 1 on their birthday in 2026. By October 29, people with birthdays from January 1 to October 29 are already 1, and the rest are still 0.

Retirement and Medicare ages for 2025
People born in 2025 can start Social Security at 62, in 2087, at a reduced rate. Their full retirement age is 67, which they reach in 2092. Each year they wait after that, up to 70 in 2095, raises the monthly amount. A January 1, 2025 birthday counts as 2024 for this rule.
Medicare starts at 65, in 2090. You can sign up in the 3 months before your birthday month, in that month or in the 3 months after.
Required minimum distributions from IRAs start at 75 for anyone born in 1960 or later, so 2100 for this group. That rule comes from the SECURE 2.0 Act of 2022.
| Milestone | Age | Year |
|---|---|---|
| Earliest Social Security retirement benefits | 62 | 2087 |
| Medicare eligibility | 65 | 2090 |
| Social Security full retirement age | 67 | 2092 |
| Social Security stops growing for delay | 70 | 2095 |
| Required minimum distributions start | 75 | 2100 |
