javascript calculate time
console.time("timer"); //start time with name = timer
console.timeEnd("timer"); //end timer and log time differencejavascript calculate time
console.time("timer"); //start time with name = timer
console.timeEnd("timer"); //end timer and log time differencejavascript difference between two dates in days
const diffDays = (date, otherDate) => Math.ceil(Math.abs(date - otherDate) / (1000 * 60 * 60 * 24));
// Example
diffDays(new Date('2014-12-19'), new Date('2020-01-01')); // 1839javascript time between two times
You can just subtract the hours right away doing it this way
var valuestart = $("select[name='timestart']").val();
var valuestop = $("select[name='timestop']").val();
//create date format
var timeStart = new Date("01/01/2007 " + valuestart).getHours();
var timeEnd = new Date("01/01/2007 " + valuestop).getHours();
var hourDiff = timeEnd - timeStart;
Here's the working fiddle http://jsfiddle.net/VnwF7/4/
UPDATE - to calculate if we are including the next day. Just add the following if block
if (hourDiff < 0) {
hourDiff = 24 + hourDiff;
}
