show us more info's, what u have done so far ? – Mom

for starters, you have Date object and setInteval to check Date – Intelligible

Will the JavaScript be persistent (i.e. server-side service / cron job) or transient (i.e. client-side web page)? – Scalf

Answer 1

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? – Inerrant

@ChristopherStrydom, with server side code. C#\Java\Ruby\PHP etc'. – Economically

@George, I don't believe this is the case here as the OP didn't mention nodejs in his question text\tags\comments. – Economically

Answer 2

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();
