The bar compresses Buckeye's whole pool year into one lane rope: gray floats for the off-season, hollow teal for the February 8–March 1 opening window, solid teal for swim weeks, hollow amber for the closing stretch that ends November 27. Wherever the today marker sits, the nearest color change is your next appointment.
