Frequently asked
How is the year/month/day breakdown calculated?
Calendar-correct: months are counted whole, then remaining days. Not a simple divide by 30 or 365. This matches how you'd normally state someone's age ("32 years, 4 months, 12 days").
Does it handle leap years?
Yes. Total days are computed from actual millisecond difference, and the year/month breakdown respects each month's real length.
Can I calculate age at a specific date?
Yes — fill in the "Age at date" field. Leave it blank to keep it live-updating against right now.
