The maths behind this project is quite simple: ([floor v] of ((days since 2000) / (365))) Basically, it's rounding down the result of dividing (days since 2000) by 365 (which should probably be 365.242, as that is the exact number of rotations the Earth makes during its orbit around the Sun).
I was inspired by "_ since 2000" by @INSERT-USER_NAME. The original project didn't have a 'years since 2000' variable, so I decided to make my own 'years since 2000' variable.
