The bar compresses Ogden's whole pool year into one lane rope: gray floats for the off-season, hollow teal for the April 27–May 18 opening window, solid teal for swim weeks, hollow amber for the closing stretch that ends October 9. Wherever the today marker sits, the nearest color change is your next appointment.
