The invention provides a timed task scheduling method, a timed task scheduling system, a timed task scheduling device and servers. The method comprises the steps: a management server acquires task information of a plurality of timed tasks and the next execution time information of each timed tasks, and transmits the next execution time information to each execution server; when the period end time of a timer is up, each execution server determines the timed task, which reaches the execution time at present, as a first task based on the next execution time information, and transmits an execution request of the first task to the management server; the management server selects one execution server to serve as a target server and transmits the task information of the first task to the target server; and the target server acquires a task execution instruction from the task information of the first task and executes the first task according to the task execution instruction. By the execution method, all the timed tasks do not need to be traversed when the period end time of the timer is up, so the data processing quantity is reduced and the scheduling execution efficiency of the timed tasks is improved.
