About Time Difference Calculator

By using the Time Duration Calculator, one can easily find the actual time difference between two specific points in time (the starting time point and the end time point). In order to use this calculator, you should enter the values of both specific time points in hours, minutes, and seconds. The result will be displayed in absolute time value and standard time format (HH:MM:SS). At the bottom of the webpage you can find some time duration example chart, which can help you understand how this Time Duration Calculator actually works.

Now button will set the starting time to the current time. And the clear button resets the time inputs.

Needs to be able to calculate from PM into AM. Using Military Time

Johaness 2019-04-23 07:55:49

someone to help please
The lessons at at our school starts at 8:00am and end at 6:30pm. If there are 7 periods of 40 minutes each, at what time do they go for break?

cate 2019-03-20 17:20:21

can you guys add the AM and PM and also have it to calculate time between different days. everything else is fine.

Kurenai 2019-03-07 11:05:30

This app is great! I use it all the time in school when I want to know when it is lunch...

Kayla 2019-02-21 13:27:32

I wish the calculator could add AM and PM and having a choice of 12 hour clock or 24 hour.

BestAtBasketball 2019-02-10 09:34:45

Amazing and easy to use! Keep this site for the future! Great for calculating time between boring classes lol!

Johnson 2019-01-25 11:25:29

Needs an AM and PM Option.

Baz 2019-01-05 19:57:33

Great little site this. Just wish there was an app version for my phone.

Also if you can't work out a 24 hour clock, you need to go back to school.

Alex 2018-12-17 07:46:12

Great for when you can't do maths and need to know how many minutes of class are left.

Aaliyah .. 2018-12-02 19:50:40

Works so well for college hwk and weekly base planning. I hope they keep 24 hour time but also make a choice for 12 hr time for those who can't translate to 24 hr time.

Jim McCracken 2018-10-16 05:39:42

Why no date? what if I needed to calculate the time between 23:50 and 01:22, for instance? That's a simplistic example, but similar to my use case today.

Cathie 2018-09-28 10:42:12

You don't need AM and PM, convert anything after noon to a 24 hour clock. (ie) 1:00 pm =13:00 2:00pm =14:00 etc. I love this for making bell schedules at our school. Great tool!

Jacob 2018-09-09 03:50:55

I use it for my work to know exactly how long it takes for trucks to be unloaded, I also don’t understand how people don’t get 24hr time.. come on it’s easy..

Additions! 2018-09-05 06:06:32

Dude it would help a lot if you added AM and PM!

Jordan 2018-07-11 11:53:06

Great time saver for converting
Ups: quick, easy, free, clear
Downs: only 24+ method, no option for a break in the middle that you have to substitute from total of work
Other than that love the site would recommend it

Ethan 2018-06-26 18:04:39

Great calculator for my itineraries

name 2018-06-11 09:24:31

For those of you who don't know how to convert between standard to military follow this:

Standard -> military
If your time after 12:00pm, take that number then add twelve.
EX: 3:00pm is 1500 in military time (12+3)

Military -> standard
If your time is greater than 1200 take that number and subtract twelve.
EX: 2300 is 11:00pm in standard time (23-12)

no 2018-05-29 12:21:01

make pm and am

Echo 2018-05-20 12:04:15

Can you please add AM and PM and put an option for standard time? Otherwise this calculator is okay.

Gideon 2018-05-15 08:12:56

Add "A.M" and, "P.M"! Also, do standered time instead of military time.

Arianna 2018-03-14 15:22:05

@ LALA "whhhattt??? in my high school we only get 30 min of lunch? -_- lol 11:50 till 12:20 some one said its 45 min but this calculator helped. thxx this is a good calculator, but u guys should add something to help with stuff like this for ex: if its 6:45 pm what time would it be in 55 min. something like that, otherwise great calc."

How can you say you have forty-FIVE minutes of lunch when at the first place there's nothing to be confused about. You might think it's 40 minutes but never 45 because its' 1150 not 1155! (obviously!)

awo 2017-09-25 17:21:38

Lala 2017-09-22 11:49:43
