How Do I Add 2 Date/times Together?

I have to add the current time with another one. For example, the time now is 10:30 on 21st July 2011. I want to book a vehicle for today at 17:00, but 10:30 + $minHours < 17:0

Solution 1:

Try this.

d.setMinutes ( d.getMinutes() + 30 );

Check the properties of Date instance here Date - MDN Docs, especially the getters and setters there.

If you want to set the hours use

//An integerbetween0and23, representing the hour
d.setHours ( d.getHours() +2 );

The signature of the method is

setHours(hoursValue[, minutesValue[, secondsValue[, msValue]]])

Code for your exact requirement is this.

var$maxHour = 17; //5 PMvar$minHours = 3;
var$hourNow = new Date().getHours();
if( ( $minHours + $hourNow ) > $maxHour ){
    alert("Time is up.");
}
else{
    alert("Please book now");
}

Solution 2:

You just make a new object. Above you refer to var d = new Date(); writing d.getDay();.

Now you make a new object: var d2 = new Date(/* something in here */); and refer to it by d2.getDay();

Is that an answer to your question?

edited. Now you can add any hours to your date:

var d = newDate();
var d2 = newDate();
d2.setHours(d.getHours() + 2);

Solution 3:

• have one date object .
• Convert the time you want to add to it into number of minutes ( or seconds ) .
• Set the minutes(seconds) of the date object as it's original value + the value computed in Step 2.
