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.

@ 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!)

bernie 2017-06-09 11:47:36

wow amazing

Zein124 2017-06-01 15:57:36

On the hours from now calculator, you should add a box for the date. For example, I play a game where bosses can be killed but they have hourly regens. As in, this enemy respawns every 75 hours. Clan member killed the enemy yesterday at 5PM. I can't calculate that since it ONLY calculates from the current time or a specific time of day, but not from a specific date. Please update.

What is the formula used? I am trying to do this in an excel sheet. I have the military time of start and finish and need the number of hours and minutes for a task (actually about 400 of them!)

Sam 2017-01-24 02:26:12

If I wanted to log this on an excel sheet, how would I do this? so I could just type the times started and finished, to = my hours and minute worked that day.

for example

7.27 5.06 =
8.25 6.27 =

Does this not like hours after midnight? It's telling me there is 8:40:00 between 09:15 and 00:35. I was hoping this would be faster then doing all the math but not so far...

Simon 2016-09-05 07:19:32

Avoid, 00, always make them 8.01 or 16.01
