I want to add in a loop here 30 minutes every time the loop runs any suggestions?

JavaScript

for (var i = setHours(8); i < toTime.count; i++) {
           toTime.setMinutes(toTime.getMinutes() + 30);

       }

Update

JavaScript

while (true) {
                    // ...
                    var toTime30 = new Date(toTime.getTime() + toTime.getTimezoneOffset() * 30 * 1000);


                    if (true) {
                        // whatever you need to do before leaving the loop 
                        break;  
                    }

If you want to add more time in a loop based on time period, you may end up running infinite loop.

It's possible that you really need to change the break loop condition inside loop though. In this case, you are using a wrong kind of loop. You would need to use the while loop. Alternatively, you use "infinite while" loop by using True condition under while, and, in this case, use break state in the if statement inside loop to break from the loop explicitly, for example:

JavaScript

while (true) {
   // ...
   breakCondition = // some Boolean condition based
                    // on the calculation performed inside loop
   if (breakCondition) {
     // whatever you need to do before leaving the loop 
     break;  
   }
}
