A duty cycle is the percent of time that an entity spends in an active state as a fraction of the total time under consideration.
In an electrical device, a 60% duty cycle means the power is on 60% of the time and off 40% of the time. The "on time" for a 60% duty cycle could be a fraction of a second – or for say, irrigation pumps, days – depending on how long the device's period is. Here one period is the length of time it takes for the device to go through a complete on/off cycle.

In a periodic event, duty cycle is the ratio of the duration of the event to the total period of a signal.
