How this is calculated
- Age is measured on October 24, 2026 in Eastern Time (America/New_York). February 29 birthdays clamp to February 28 in non-leap years. This is a calendar calculation, not a legal age determination.
- Year-only mode reports a range. Birth dates later than today are not included.
- For an earlier birth year, a birthday on or before today gives the older age; a birthday later in the year gives the younger age. On December 31, all birthdays for that year have occurred.
- Month rows cover only possible birth dates on or before today. Milestones show the year of that birthday, not an exact date.
