Age By Weeks Formula
The following equation is used to calculate the total number of weeks lived.
W = (CD - BD) / (1000 * 60 * 60 * 24 * 7)
- Where W is your age in weeks
- CD is the calculation date
- BD is your birth date
- (1000 * 60 * 60 * 24 * 7) is the number of milliseconds in one week
To calculate your age in weeks, subtract your birth date from the calculation date and then divide by the number of milliseconds in a week.

How to Calculate Age in Weeks?
Example Problem:
The following example outlines the steps and information needed to calculate your total weeks lived.
First, determine your birth date. In this example, it is January 1, 1990.
Next, determine the calculation date. In this example, it is January 1, 2020.
Finally, calculate your age in weeks using the formula above:
W = (CD - BD) / (1000 * 60 * 60 * 24 * 7)
W = (January 1, 2020 - January 1, 1990) / (1000 * 60 * 60 * 24 * 7)
W ≈ 1565.286 weeks
