    Numerologists take note: tomorrow, 27th September 2025, is a square date in both US and Everywhere Else notation.

    5205² = 27092025 and 3045² = 9272025

    This is the last time this will happen for a thousand years! (except trivial dates where the US and Everywhere Else forms are the same)
