refresh page at a specific time

hear me out. suppose a page has to be reloaded every weekday at 9:30 am. the page is opened at 9 am. so at 9:15 am the page should automatically get reloaded without any user intervention. what can be done. any help is appreciated

 function checkTime() {
        var d = new Date(); // current time
        var hours = d.getHours();
         var mins = d.getMinutes();
         if (hours >= 17 || hours <= 18) {
          setInterval(() => {
           location.reload();
             }, 5000);

                   }

                }
