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 hours

We have left
25545 seconds - (7×60×60) sec
= 25545 - 25200 sec
= 345 seconds

Calculating minutes
total minutes = 345 ÷ 60
total minutes = 5 minutes

We 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 hour

We have left
5115 seconds - (1×60×60) sec
= 5115 - 3600 sec
= 1515 seconds

Calculating minutes
total minutes = 1515 ÷ 60
total minutes = 25 minutes

We have left
= 1515 - (25 × 60) seconds
= 15 seconds

So the result is
  2:15:30
- 0:50:15
-------------
  1:25:15

We also recommend Metric units converter for all other metric units conversions.

Nice. Have been looking for something that can convert min to hours and min. Say, 118 min to have it show me 1 hr 58 min. On some sites, movie times are only shown in min, but I want the hours and min. So, thank you for this.

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!

Paul 2018-02-17 14:32:26

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.

parvind 2018-02-16 21:01:09

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

Susan W. 2018-02-14 18:46:21
