How This Works
This adds each milestone (a round number of years or days) to the birth date to find the exact calendar date it falls on — a fun way to plan celebrations for round-number ages or day counts like turning 10,000 days old.
Formula
Milestone Date = Birth Date + Milestone (years or days)
Example
Someone born May 14, 1990 turns 10,000 days old on December 27, 2017, and their 50th birthday falls on May 14, 2040.
