Understanding the Basics

The relationship between age and date of birth is straightforward: your age marks the passage of time *since* your birthdate. So, to find a possible birthdate, you essentially subtract the age from the current date. However, there are nuances to consider, such as leap years and varying days in different months.

Manual Calculation: A Step-by-Step Guide

While manual calculation is possible, it can be tricky. Here's a simplified approach:

  1. Start with a Reference Date: This is typically the current date or any date for which you know the person's age.
  2. Subtract the Years: Subtract the person's age (in years) from the year of the reference date.
  3. Consider the Month and Day: This is where it gets more complex. You'll need to account for whether their birthday has already occurred in the reference year. If not, you'll need to adjust the month and possibly the year.

Example: Suppose today is July 20, 2024, and you know someone is 30 years old. Subtracting 30 years gives you the year 1994. However, if their birthday is in November, they are still technically 29, and their birth year would be 1993. You will be off by one!
