2025 is the only year this century that's a perfect square (45 x 45 = 2025), making it pretty special mathematically.
It's also the first year since 1520 divisible by 5, which is quite a long time between similar numbers!
There's even a unique equation where it's the result by adding 20 and 25 then squaring it.
This year inspires lots of fun math puzzles, like arranging queens and pawns on a 25-square grid, and creating triangles from a five-pointed star.
