The bar compresses Fort Worth's whole pool year into one lane rope: gray floats for the off-season, hollow teal for the February 28–March 21 opening window, solid teal for swim weeks, hollow amber for the closing stretch that ends November 14. Wherever the today marker sits, the nearest color change is your next appointment.
