Calculating age seems simple at first glance: subtract the year you were born from the current year. However, real chronological time demands higher precision.

Months in the Gregorian calendar span 28, 29, 30, and 31 days. Simply multiplying elapsed years by 365 produces significant drift over a lifetime.

Ageify uses discrete monthly milestone detection to guarantee that your completed months, weeks, and days always align with the legal calendar.
