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

i have just used this to add up the time for the first side of "Beatles Revolution" album and proved that the first side does not work because "Hey Jude" would make 27 minutes and 9 seconds. A side of vinyl is only 22 minutes. Shame.
