Where 2025 fits
Why 2025 is special
It is also a perfect square, 45 x 45 — the first since 1936 and the last until 2116, so most people will see one such year in a lifetime and many will see none. The coincidence of a memorable square with a year of documented events is worth separating: the arithmetic is a property of the number, and the papal succession is something that happened while the calendar read that way.

In historical numeral systems
Egyptian
2 lotuses, 2 hobbles, 5 strokes
2 × 1,000 + 2 × 10 + 5 × 1 = 2,025. The signs are simply repeated and added; where they sit on the line is a matter of layout, not value.
Babylonian
3 corner wedges + 3 vertical wedges (sixties place), 4 corner wedges + 5 vertical wedges (units place)
33 × 60 + 45 = 2025. Places are separated by a space on the tablet, with the higher place written first.
Systems that simply cannot reach this value are left out. Where a script needs a font most readers do not have, the reading is given instead of the glyphs — see number systems for each system in full.
