The bar compresses Citrus Heights's whole pool year into one lane rope: gray floats for the off-season, hollow teal for the March 25–April 15 opening window, solid teal for swim weeks, hollow amber for the closing stretch that ends November 9. Wherever the today marker sits, the nearest color change is your next appointment.
