### Add Hours Minutes Seconds to Time Calculation

On the following time calculation steps, we show how to add time in seconds.

Let's say starting time is 2:15:30 Add 4:50:15 1 hour = 60 × 60 seconds 1 minute = 60 seconds Calculating starting time in seconds 2:15:30 = (2×60×60 sec) + (15×60 sec) + 30 sec = (7200 sec) + (900 sec) + 30 sec = 8130 seconds To add 4:50:15 to starting time We calculate seconds too 4:50:15 = (4×60×60 sec) + (50×60 sec) + 15 sec = (14400 sec) + (3000 sec) + 15 sec = 17415 seconds Now let's add starting seconds = 8130 seconds + 17415 seconds = 25545 seconds Calculating days 1 day = 24 hours 1 day = 24×60×60 seconds 1 day = 86400 seconds We got 25545 seconds total days = 25545 ÷ 86400 total days = 0 Calculating hours We got 25545 seconds total hours = 25545 sec ÷ (60×60 sec)total hours = 7 hoursWe have left 25545 seconds - (7×60×60) sec = 25545 - 25200 sec = 345 seconds Calculating minutes total minutes = 345 ÷ 60total minutes = 5 minutesWe have left = 345 - (5 × 60) seconds = 45 seconds So the result is 2:15:30 + 4:50:15 ------------- 7:05:45

### Subtract Hours Minutes Seconds from Time

On the following time calculation steps, we show how to subtract time in seconds.

Let's say starting time is 2:15:30 Subtract 0:50:15 1 hour = 60 × 60 seconds 1 minute = 60 seconds Calculating starting time in seconds 2:15:30 = (2×60×60 sec) + (15×60 sec) + 30 sec = (7200 sec) + (900 sec) + 30 sec = 8130 seconds To subtract 0:50:15 from starting time We calculate seconds too 0:50:15 = (50×60 sec) + 15 sec = (3000 sec) + 15 sec = 3015 seconds Now let's subtract from starting seconds = 8130 seconds - 3015 seconds = 5115 seconds Calculating days 1 day = 24 hours 1 day = 24×60×60 seconds 1 day = 86400 seconds We got 5115 seconds total days = 5115 ÷ 86400 total days = 0 Calculating hours We got 5115 seconds total hours = 5115 sec ÷ (60×60 sec)total hours = 1 hourWe have left 5115 seconds - (1×60×60) sec = 5115 - 3600 sec = 1515 seconds Calculating minutes total minutes = 1515 ÷ 60total minutes = 25 minutesWe have left = 1515 - (25 × 60) seconds = 15 seconds So the result is 2:15:30 - 0:50:15 ------------- 1:25:15

I think this is a great and efficent tool to help with school and just to solve simple problems that you just can't wotk out in your head. But the only thing that this calculator needs is am and p option or else it gives you the wrong time difference or sum.

Wow I love this time calculator

I agree with parvind

I used it for my mathematics homework

Wow,it helped me a lot

For anyone who has an obsession with keeping time, this tool is an absolute necessity! Your exact breakdown of the calculations is especially helpful when I'm at work, and I want to make the most out of my time. Now I can keep track of exactly how long it takes to get help from , so I'm not wasting my time waiting for answers that I could spend less time finding on my own! Every second certainly counts!

this is the best love it

Ans ca ahhhhhhhaxSdq 013 456-7910 right get on the weather though 013 456-7910 right get on the weather though traffic and weather together every 10:00 on the eights

Thanks. This did what I needed, but it would have been so much nicer if I could have just entered the time as 6:04 pm, for example, instead of having to break it up myself. Using Javascript, you could use the string function "split(":") to split the time into the separate boxes. You'd probably have to verify inputs, but you have to do that anyway.

good! But it would be great if it allow adding multiple entries at the same time .

Why don't you have an app?
