FAQ
How is age calculated exactly?
Whole years first, then whole months, then leftover days — the same way official forms count it.
Why does my age in months look odd?
Months differ in length, so '3 months' from Nov 30 lands on Feb 28/29 — we follow calendar rules, not 30-day months.
Can I calculate age at a past or future date?
Yes, change the 'as of' date.
