Node Scheduler Repetition

A friend and I are trying to use Node Scheduler to have a discord bot announce things on certain days (Essentially a holiday calendar). We want it to post one pre set message, but it seems to post the messages a random amount of times. 

    var Hb = schedule.scheduleJob('* 6 14 20 4 *', function(){
bot.channels.get('435858985501982720').send('new message 3');
});

This is our tester code, does anyone know what's wrong?

Edit: we do want specific minutes, idk if that has any affect.

The first argument of schedule.scheduleJob is a string representing when the function should fire, in cron format. According to the documentation you are trying to run the function:

  • every second
  • 6 minutes past the hour
  • 14th hour (2pm)
  • 20th day of the month
  • 4th month (April)
  • every day of the week

aka every second at 2:06pm on 20th April every year.

I would rewrite the cron string using the format the docs provided:

*    *    *    *    *    *
┬    ┬    ┬    ┬    ┬    ┬
│    │    │    │    │    │
│    │    │    │    │    └ day of week (0 - 7) (0 or 7 is Sun)
│    │    │    │    └───── month (1 - 12)
│    │    │    └────────── day of month (1 - 31)
│    │    └─────────────── hour (0 - 23)
│    └──────────────────── minute (0 - 59)
└───────────────────────── second (0 - 59, OPTIONAL)

e.g. to run at midday on Christmas every year:

schedule.scheduleJob('0 0 12 25 12 *', function(){
     bot.channels.get('435858985501982720').send('new message 3');
});
