Hi

Using javascript I want to calculate hours between 2 times along with lunch break.

EG:
Start Time - 9:00 AM
End Time - 5:00 PM
Lunch Time - 0.30(i.e 30 minutes)

Output should Be: 7.30 hours.

Can anyone please help me on this?

Thanks,
Meenakshi

You can make use of http://momentjs.com/[^]

Sample code

C#

var StartTime = moment("9:00 am", "hh:mm a");
var EndTime = moment("5:00 pm", "hh:mm a");
var Lunch = moment("0.30", "hh.mm");
var TotalTime = ((EndTime.subtract(StartTime)).subtract(Lunch)).format("hh.mm");

Regards..

Solution 1

Parse the strings to obtain a common unit (e.g. minutes)

9:00 AM ->  9*60 ->  540
5:00 PM -> 17*60 -> 1020
0.30 -> 30

Subtract both Start Time end Lunch Time from End Time

1020 - 540 - 30 -> 450

Convert the result from total minutes to hours and minutes

450 -> 7*60 + 30 -> 7.30

Yeah this looks good.
What to do in case of below condition?

Start Time - 9:30 AM
End Time - 5:30 PM
Lunch Time - 0.30(i.e 30 minutes)

Output should Be: 7.30 hours.

Thanks,
