Answer 1

use Date objects. Date.setHours() allows you to specify hour, minutes, seconds

var currentD = new Date();
var startHappyHourD = new Date();
startHappyHourD.setHours(17,30,0); // 5.30 pm
var endHappyHourD = new Date();
endHappyHourD.setHours(18,30,0); // 6.30 pm

console.log("happy hour?")
if(currentD >= startHappyHourD && currentD < endHappyHourD ){
    console.log("yes!");
}else{
    console.log("no, sorry! between 5.30pm and 6.30pm");
}

Similar to @Arjun Sol, instead of using Date.parse, you could just grab the times from the string itself, create a new Date object and do the comparison.

const time1 = '12:42';
const time2 = '18:30';

const getTime = time => new Date(2019, 9, 2, time.substring(0, 2), time.substring(3, 5), 0, 0);

const result = getTime(time1) < getTime(time2);
console.log('This should be true:', result);
                                                                    

                                                        
            
            

              
                
                0

Answer 3

Date.parse('25/09/2013 13:31') > Date.parse('25/09/2013 9:15')

EDIT:

Note that you are parsing an arbitrary date that you're not interested in, it just needs to be the same on both sides.

Answer 4

 if(Date.parse('01/01/2011 10:20:45') == Date.parse('01/01/2011 5:10:10')) {
  alert('same');
  }else{

  alert('different');

  }

The 1st January is an arbitrary date, doesn't mean anything.
