Two birthdates → the exact gap in years, months, days, plus total days and weeks — and who is older.
How to use

- Calculate.
- Read the broken-down gap and totals.
What it supports
Calendar-broken-down difference (the way ages count), plus plain day and week totals. Dates between year 1 and 9999. Order does not matter — 'who is older' is part of the result.
