How can I execute this with different timings? Please help on this. Thanks in Advance...

const Cron = require('node-cron');
const Cron2 = require('node-cron');

var TaskOne = Cron.schedule('*/10 * * * *', async() => {
     
    //first job implemented here and its working fine  
    function1();
 });
 
 var TaskTwo = Cron2.schedule('*/11 * * * *', async() => {
     
    // Second job implemented here....
    //Why this block is not getting executed??????????????????????? 
    function2();    
});

mm agenda also needs an external storage though.. isn't there anything that's self contained? – PptSbzzgt Sep 22 '22 at 06:28

There's no need to require the same package twice, so you should remove Cron2 on the second line. Thus the line var TaskTwo = Cron2.schedule('*/11 * * * *', async() => { should be changed to:

var TaskTwo = Cron.schedule('*/11 * * * *', async() => {

As for why the second schedule is not working, it might be because you didn't start() the schedule, as shown in https://github.com/node-cron/node-cron#start. So adding the code below at the end of your script might trigger both cron to run:

TaskOne.start();

TaskTwo.start();
