Happy New Year! I was scrolling through Facebook when Maria O pointed out that 2023 is 717^2. That seems interesting. Are there other times in our lifetime that the year is NNN^N?
It last happened in 2020. We have a run of them, coming up:
But even cooler is 2025, which is the perfect square of 45^2. Unless you were alive in 1936 or will be alive in 2116, the square year of 2025 will be the only square in our lifetimes
