How Age is Calculated
Understanding the mechanics of time measurement
Years, Months, and Days
The most common way to express age is in full years, followed by full months, and then remaining days. This method matches how we intuitively think about age ("I am 25 years and 3 months old").
1. Count full years from birth date.
2. Add those years to birth date, then count full months to target date.
3. Add those months, and count remaining days.
The Leap Year Factor
Leap years (occurring every 4 years) add an extra day (February 29th) to the calendar. Age calculations must account for this to be precise.
For example, a person born on Feb 29, 2020, technically has their first "birthday" on Feb 28 or Mar 1 in 2021, depending on the legal definition in their region.
