Abstract An event timer device having a plurality of memory counters each for memorizing the duration of a respective event. A selecting circuit selects one of the memory counters corresponding to a selected event having a predetermined duration for operating the selected memory counter to count down the memorized duration of the selected event. A display displays the remaining time of the selected event. The event counter further includes an alarm for generating an alarm signal at the end of the selected event.
