A method for simultaneously timing multiple entities uses a timekeeping device. During timing, each of the multiple entities runs through a process starting with a start time event in a start phase followed by at least one subsequent time event in a run phase. The method comprises the following steps. In the start phase, when a first start time event occurs, a first actuator is manually actuated and the manual actuation triggers the measuring and recording of a first start time by a time measuring means. In the run phase following the start phase, when a subsequent time event occurs, the first actuator is manually actuated and the manual actuation triggers the measuring and recording of a subsequent time by the time measuring means. The timekeeping device also includes an assignment means and a second actuator.
