Verify Age for Legal Requirements

Legal age thresholds (18, 21, 65) are checked to the day. Use this to calculate the exact date someone reaches a legal age milestone.

Retirement age calculations: enter your birth date and today's date to see exact years until retirement at 62, 65, or 67.

The "as of" date field lets you calculate age on any specific date — useful for verifying someone's age on a document date, not today.
