What is the Age Calculator & How does it work?
The Age Calculator determines the exact age from a birthdate to today. It breaks down the age into years, months, and days. Additionally, it provides a countdown to the next birthday and calculates the total number of days, weeks, and months lived.To calculate the age, subtract the birth year from the current year, then adjust for months and days. The formula for calculating the difference in years is: Years = Current Year – Birth Year. Adjustments are made for months and days to ensure accuracy.
Years = C_y – B_y; Months = (C_m – B_m) mod 12; Days = (C_d – B_d) mod 30
C_y = Current Year, B_y = Birth Year, C_m = Current Month, B_m = Birth Month, C_d = Current Day, B_d = Birth Day
