I need it to run at a specific time of day.

In that case, I'm completely stumped why this prior code didn't work. Are you sure you had the hour and minute set after the local time of your computer when you ran it?

  

class TimerThing {
    public static void main() {
        Timer timer = new Timer();
        Calendar date = Calendar.getInstance();
        date.set(Calendar.HOUR, 13);
        date.set(Calendar.MINUTE, 21);
        date.set(Calendar.SECOND, 0);
        date.set(Calendar.MILLISECOND, 0);
        timer.schedule(
                new TimerTask() {
                    @Override
                    public void run() {
                        System.out.println("Test");
                    }
                },
                date.getTime(),
                1000 * 60 * 60 * 24
        );
    }
}

Well I guess that was the issue. I'm not sure if it had to do with the fact that I'm on windows but it works now.

Thanks @BobVonBob  for all the help. I really appreciate it!

Nope, instead of setting Calendar.HOUR, you should set Calendar.HOUR_OF_DAY. I totally missed this before, and finally gave up and tried the code locally. That was the problem.

¯\_(ツ)_/¯
