To schedule an Apex class to run at regular intervals, first write an Apex class that implements the Salesforce-provided interface Schedulable.
The scheduler runs as system—all classes are executed, whether or not the user has permission to execute the class.
To monitor or stop the execution of a scheduled Apex job using the Salesforce user interface, from Setup, enter Scheduled Jobs in the Quick Find box, then select Scheduled Jobs.


The following example implements the Schedulable interface for a class called mergeNumbers:
  
global class scheduledMerge implements Schedulable {
   global void execute(SchedulableContext SC) {
      mergeNumbers M = new mergeNumbers(); 
   }
}


The following example uses the System.Schedule method to implement the above class.
  
scheduledMerge m = new scheduledMerge();
String sch = '20 30 8 10 2 ?';
String jobID = system.schedule('Merge Job', sch, m);

Hi admin,
You schedue the apex job to execute at specified time.
Below are the more details:
