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 love the app. The only one I've found if it's kind. Helps me tremendously with my time. The only problem I have is the ads covering up after the calculations. Some of them are too large & I have to go back & redo several times before I can read the answers. Google says they'll try not to show the add again but it comes up the very time after next.
i like this app bc it helps me track time
Thanks for this app it’s helped me a lot with keeping track of time!
Maybe you could add times of the day with options of military time or regular time?

i love this app i have a math test that have lots of time and i just finished it and got an a+

I think this app is REALLY helpful, and people took TIME and EFFORT to make this app. So stop complaining and be thankful this app is here to help a little. ALSO!!! Figure out the multiplication by yourselves! I am in 7th grade and I am pretty smart how to divide and multiply time and convert minutes to seconds.
I use this in class when I need to know when is the next period
Perfect!!!
I have a schedule and with this any math is easy!
The app is soo useful!! Rating: 10/10
I would like more slots like multiplication and division and you should be able to add minutes+minutes+minutes+seconds for example. I would also want to have bigger time slots like days, weeks, months, years, and maybe decades, centuries, and melaniums. I hope the owner sees this and improves this website. Other than that its very useful.
i am surprised of how it calculates i enjoy it
This is great!!!
This site is good with dreambox, I Like it
★★★★☆ 4 star rating:
It would be even better if you had a choice for multiplication and division and if you can find the duration of two times.
