how to calculate the datetime difference in microsoft excel? - excel

I have two columns with datetime values in this format dd/mm/yyyy hh:mm:ss.How do i calculate the difference between two columns in minutes and show a value if it exceeds certain minutes. For example if the difference of column B - A is less than 5 minutes, than it should show 'ok' else it should show 'fail'. Example
A B C
8/5/2015 3:25:00 PM 8/5/2015 3:35:00 PM Fail

All that is needed is this formula:
=IF((B1-A1)*1440<5,"OK","Fail")
(B1-A1)*1440 returns the number of minutes difference.
We're assuming that the second time is greater than the first. (And also assuming the same time zone.)

You can use the Hour(), Minute() Day() and month() functions to create an amalgam formula - it doesn't seem particularly sensible to do with numbers alone using cell-INT(cell).

Extract the hour from the h" hour(s) and "m" minute(s)" in excel

I have the list of data that showing the Hours and the Minutes that I extract from the system. I need to be extract the hours.
As example below, column B first row, the Hours would be 64 and the minutes would be 46.
But when I used the formula =Hour , its turn up the different value since its actually decimal number.
Cannot use left() , it will give the actual decimal number.
Updated:
We tried the #harun24HR 's but cannot readable the value.
But if you noticed, if i copy and paste the value is different. thats why the search not applicable.
4th Update:
To Solar Mike, I have tried the formula given from the thread the i think the value not readable
It's a time value which Excel stores as calculated value based on 24 hours = 1.
To retrieve the hours only you can use:
=INT(A2*24)
To retrieve the minutes only you can use:
=(A1-(INT(A1*24)/24))*24*60
Your time value is already a number in time format so you just need it to change it to decimal system. Dates and time values are numbers. Even if you see it as 30/09/2019 or 12:00:00, actually, for Excel, both cases are numbers.
First date Excel can recognize properly is 01/01/1900 which integer numeric value is 1. Number 2 would be 02/01/1900 and so on. Actually, today is 44659.
Now, about your data, you posted this screenshoot:
So the value is numeric, not text/string. In Excel, what you see is not always what you have. Probably that column has been formatted using custom mask. My fake data is like this:
The numeric value is 02/01/1900 16:46:36 (or 02/01/1900 4:46:36 PM it depends on your regional settings) but I've applied a custom format like this:
[hh]" hours" mm " minutes"
So what I have is a number but what I see is a text!
We have to work with the number (to be honest, ist's easier to work with numbers), so to extract the total hours, minutes and seconds.
Formula in B1: =INT(A1*24) total hours
Formula in C1: =INT(A1*24*60-B1*60) total minutes
Formula in D1: =A1*24*60*60-B1*60*60-C1*60 total seconds
This should guide you on whatever are you trying to achieve.
From your current sample data you try-
For hour =LEFT(A2,SEARCH(" ",A2)-1)
For minutes =RIGHT(SUBSTITUTE(A2," minutes",""),2)

calculate time difference in milliseconds excel

How do i calculate time difference in milliseconds between two columns where value of time has milliseconds component ... i.e. 16:33:44:056. Please refer to column E and J in pic .. i want to calculate difference in milli seconds between J and E ...
I have tried using the following formula to alculate difference in milli seconds but its giving incorrect results. =((RIGHT(J1,3))-(RIGHT(E1,3)))
It appears your date/time is a text value.
A "real" time value would normally be seen as 16:11:52.052
But by replacing the last : with a ., excel will see it as a real time and ordinary math can be done.
Excel stores date/time as days and fractions of a day.
So a formula that should work:
=ROUND((SUBSTITUTE(J1,":",".",3)-SUBSTITUTE(E1,":",".",3))*86400000,0)
Format the result as General or as Number with no decimal places
Try
=(J1-E1)*1000*60*60*24
or more concisely
=(J1-E1)*86400000
Then format your formula column to general.
This assumes the data is actually stored as datetime and not a text value.
If you change the format of your time columns, and the column to show the difference, to
hh:mm:ss.000
You can simply use subtraction:
(You'll have to tweak the actual cells to have . before the milliseconds, just formatting won't do it)
If the part of that string corresponding to hours, minutes and seconds is always the same, and time in J is always bigger than time in E, you could do:
=VALUE(RIGHT(J1;3))-VALUE(RIGHT(E1;3))

Excel: Comparing Times to get minutes apart

I'm trying to get the + and - between two times but if the time I am subtracting from is greater than the time I am subtracting it gives me the difference in 24 hours.
I would like it to show this:
Perhaps this needs to be done in VBA. Have column B be the time to compare to and put max time apart as 12 hours, either positive or negative. So if the time is different by over 12 hours it becomes a negative instead of positive or vise-versa?
#tysonwright that is the best way to do it. Thanks. I assumed there was a better process but apparently there is not. So with that, I change the date to the next day to get 23:59 to 0:01.
If your clockin is in A1 and your Schedule is in A2, your Difference should be:
=IF(A1>B1,TEXT((A1-B1),"-h:mm"),TEXT((B1-A1),"h:mm" ))

How can I extract the hour part from a duration value in Excel?

How can I convert duration in excel to text ? I am having 1037:00:00 in a cell, which is the sum of certain durations. I want to extract 1037 alone. Excel returns "hours" when I try to extract with MID or use TEXT function.
If it is really the sum of some durations you can get the amount of hours by multiplying the cell by 24. The internal representation of a date or time cell is the number of days since beginning of the year 1900, so you have to multiply it by 24 to get the number of hours. (The year 1900 is not interesting for you as you just want a time span.) The Hour function does not work here because you get the day hour which is 5 in this case.
Be sure to format your target cell as regular number.
lets assume your cell with 1037:00:00 is in cell L40. You can use the following formula to pull the hours.
=INT(L40)*24+HOURS(L40)
Note this will only pull full hours rounded down. It does not take into account minutes or seconds.
Alternatives:
=Rounddown(L40*24,0)
This alternative is what Fratyx explained in his answer.

What is wrong with this calculated field for total hours between two times in SharePoint 2007?

I am attempting to get the total hours between two times in a SharePoint 2007 list. Right now I have the formula as...
=INT(([Column2]-[Column1])*24)
...which I have looked up and says that it is the correct formula to do this. But, what I get is a weird date like "2/18/1900 12:00 AM" instead of what it should be: 26.
Another formula I tried was...
=TEXT([Column2]-[Column1],"h")
...but, this will only get the difference in hours and not count the days (if they are more than one apart).
Both of the columns are Date & Time columns. So, what am I doing wrong?
My take is that you set the output format of the calculated column to be Date and Time, while it should be of type number.
In a calculated column, the number of hours between two times is:
=TEXT([Column2]-[Column1],"h")
Providing that the difference is less than 24 hours. Otherwise, you'll need to look at getting the days difference and doing a multi-step calculation involving the number of days between the dates * 24 + the calc above.
