*And* it’s the sum of all single digit numbers cubed:
1³+2³+3³+4³+5³+6³+7³+8³+9³ = 2025

Happy 2025 = 45², the first “square” year since 1936, the next being 2116. Its digit sum is also a square: 2+0+2+5 = 9 = 3². This last happened in 1681 and next occurs in 2304. And not since 900 has the year divided by the digit sum been a square too: 900/9=100 = 10² & 2025/9=225 = 15² QED. 👀🎉😁
