Creating Scheduled Task in JavaScript

Question

I am creating an application in javascript which send notification on every sunday 12.00 am.
What should I do to call a function on that time.

for starters, you have [Date object](https://developer.mozilla.org/en/JavaScript/Reference/Global_Objects/Date) and [setInteval](https://developer.mozilla.org/en/DOM/window.setInterval) to check Date — Joseph, May 09 '12 at 12:51
Will the JavaScript be persistent (i.e. server-side service / cron job) or transient (i.e. client-side web page)? — vansimke, May 09 '12 at 12:52
Ah, I see you've edited your comment. Well, that makes mine useless, deleting. :) — Elliot Bonneville, May 09 '12 at 12:57

I wouldn't do it with javascript

That said(with shouting...)

function foo(){
    var day =new Date().getDay();
    var hours =new Date().getHours();
    
    if (day === 0 && hours >12 && hours < 13)  // day is a 0 index base
                                               // sunday between 12:00 and 13:00
        // Do what you want here:
}

setInterval(foo, 3600000); // one hour check.

so what would you do it with? – ChristopherStrydom Jul 26 '13 at 16:16
@ChristopherStrydom, with server side code. C#\Java\Ruby\PHP etc'. – gdoron Jul 27 '13 at 23:50
@George, I don't believe this is the case here as the OP didn't mention nodejs in his question text\tags\comments. – gdoron Sep 10 '13 at 16:32

another solution is 3rd parties like: cron

var CronJob = require('cron').CronJob;
var job = new CronJob('0 0 0 * * 0', function() {
  console.log('You will see this message every sunday, 12 am');
}, null, true, 'America/Los_Angeles');
job.start();
