Some years ago I contributed to a package called "date-events".

This package is exactly build for your use case.

And yes, like Marco Alka said, you should combine it with something like "forever" or "pm2".

The easiest way would be to use the default scheduler of the operating system you are on (for example cron on most *NIX) which triggers the task. Other than that, you might want to use forever or pm2 to get your node application started and then construct your own scheduler like this:

// todo: error management
// todo: improve architecture and patterns

const fs = require('fs');

// on startup, read last execution time
let lastExecTime = new Date(fs.readFileSync('lastExec.txt', { encoding: 'utf8' }));

// this is the scheduler which fires every minute
function customSchedule() {
  const now = new Date();

  // check if 3600000ms (=1h) have passed
  if (now - lastExecTime > 1000 * 60 * 60) {

    // run hourly task here

    // remember last execution time
    lastExecTime = now;
    fs.writeFileSync('lastExec.txt', now.toString());
  }

  // fire the next time in 1min
  setTimeout(customSchedule, 1000 * 60);
}

// start the scheduling
customSchedule();

It will fire every minute and check if an hour or more has passed since the last execution. If so, it will execute your hourly task. For the daily/weekly ones, I leave the implementation to you :)

As for hosted services, many PHP-hosters allow for cron schedules. As for nodejs hosters, you can just roll the above code :)

Best way to run some tasks periodicaly is to use CRONS or Celery.

There is nodeJs wrapper for Celery which you can use to create periodic tasks .

Even using CRON is also better option. NodeJs wrapper for cron
