How the 15‑year calculation works
Subtracting 15 years is straightforward with our JavaScript engine. It handles leap years automatically—for example, February 29, 2020 minus 15 years lands on February 29, 2005? Wait, 2005 was not a leap year, so the date rolls to March 1. Our calculator shows that adjustment.
If you start on February 29 and go back to a non‑leap year, the result becomes March 1. We display the correct adjusted date.
