Datewise Age & Date Calculator

Datewise handles three things people constantly need to calculate about
dates, with real calendar math — not rough estimates.

AGE: enter a birth date, get a precise years/months/days breakdown, plus
total days, weeks, and months lived.

DIFFERENCE: pick any two dates and see exactly how far apart they are —
both as a clean breakdown and as total days, weeks, and hours.

COUNTDOWN: track any anniversary or recurring date and see exactly how
many days until it comes around again. Save the ones you want to keep an
eye on.
