How Is Age Calculated? (The Logic)
Calculating age isn't just about subtracting years. Our tool handles the complex math behind the scenes:
The Leap Year Factor
Every 4 years, February adds a day. We account for all leap years since your birth to ensure day-perfect accuracy.
Month Adjustment
Since months have 28, 30, or 31 days, we calculate the exact difference based on calendar days, not just an average.
// The Formula
Age in Milliseconds = Compare Date (Timestamp) - Birth Date (Timestamp)
Total Days = Math.floor(Age in Milliseconds / (1000 * 60 * 60 * 24))
Chronological Age
"The count of time."
This is based purely on the calendar. It increases at the same rate for everyone—one year every 365.25 days.
Biological Age
"The health of your cells."
Based on how well your body functions. It can be higher or lower than your actual age depending on lifestyle and genetics.
