Why this Pokémon
September 15 is day 259 of the year on a leap-year calendar. Divided by 366 that leaves a remainder of 259, and every Pokédex number leaving the same remainder belongs to this date. The lowest of them, No.259, is the one this page leads with.
The straightforward reading — 27 July becomes No. 727 — breaks down in November, where the numbers run past 1025 and leave those birthdays empty. Cycling through 366 keeps every date filled.
