### 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
