The bar compresses Johns Creek's whole pool year into one lane rope: gray floats for the off-season, hollow teal for the March 26–April 16 opening window, solid teal for swim weeks, hollow amber for the closing stretch that ends October 27. Wherever the today marker sits, the nearest color change is your next appointment.
