The bar compresses Dalton's whole pool year into one lane rope: gray floats for the off-season, hollow teal for the March 29–April 19 opening window, solid teal for swim weeks, hollow amber for the closing stretch that ends October 28. Wherever the today marker sits, the nearest color change is your next appointment.
