Examples for Time Calculator

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
