sails.js-hook-scheddule - how to specify cron timing string

How can i specify the timings for scheduling a task in sails-hook-schedule? I got this basic example from their docs.

module.exports.schedule = {
  sailsInContext : true, //If sails is not as global and you want to have it in your task
  tasks : {
      //Every monday at 1am
      firstTask : {
         cron : "0 1 * * 1",
         task : function (context, sails)
         {
              console.log("cron ok");
         },
         context : {}
      }
  }
};

Now what does this line means?

cron : "0 1 * * 1",

What i understood is that this is how i specify the timings for the schedule. I wanted to run a specific task at every 12 am in the morning. Can anyone help me with this?

You can use this link - Cron Tab Guru to find out what the cron expression mean. It gives you the description of the cron expression. I find it very useful.

This string is a cron expression. Cron allows the users to schedule jobs to run periodically at fixed times, dates, or intervals in Unix-like computer OS.

You can find plenty of tutorials online to learn how to write one.

You've also got helpers to translate a cron expression in plain english, or to generate a cron expression.

The one you gave run the task method on mondays at 1 am.

If you want to schedule it to run at 12 am on each morning, you can use this cron expression: 0 0 * * *.
