The core principle is subtracting the age from a known date (usually today's date) to arrive at the birth date. Sounds easy, right? It can be, but accounting for months and days makes it slightly more complex. Here’s a breakdown:
- Years: Subtract the age in years from the current year.
- Months: Adjust the month accordingly. If the current month is before the birth month, you'll need to adjust the year.
- Days: Similarly, adjust the day. If the current day is before the birth day, you'll adjust both the month and potentially the year.
Manual Calculation: A Step-by-Step Guide
Let's say today is October 26, 2024, and you know someone is 25 years old. Here’s how you'd calculate:
- Start with the current date: October 26, 2024.
- Subtract the age in years: 2024 - 25 = 1999.
- Keep the month and day the same initially: October 26, 1999.
- Check if adjustments are needed: Since we don't know the exact birth month and day, this is our best estimate.
If you knew the person was *going* to turn 25 on December 10, 2024, then their birth date would be December 10, 1999. Knowing the birth *month* and *day* significantly increases accuracy.
