This calendar is owned by my colleague Pekka Vayrynen and maintained by many colleagues in Leeds PRHS. For those in Leeds the best way we’ve found to use it is to subscribe to the calendar and have it synch with your personal diary–this is possible in both outlook and ios (other operating systems are avialable).
