I have a date with hours and minutes like 2/3/2019 10:30 am , and I do the following to find the diffence in hours which I already formatted like ( h )
=now() - date
I want to check if the difference is more than 12 ( where I mean 12 hours) to do something.
if(actual difference>12; "hello"; "bye")
But is not checking the actual difference but the serial difference
How can I check the actual difference in hours?
Dates are stored as numbers where the integer part is the number of days since 1899-12-31. The fractional part measures the time within a day. So, 24 * (now() - date) will give you the number of hours elapsed.
NB: the formatting is only a question of display and won't influence what's done by the formulas.
In order to check conditionaly the difference in the hours unit between two times we can do if(hour(actual difference)>12; "hello"; "bye")
We put the function hour() as noted in

I'm using manipulating time in excel.
I have the date in minutes I want to convert it into the format.
YY MM DD HH mm
where:
mm:Minutes
HH:Hours
DD:Days
MM:month
YY: year
Im using the following logic:
For 124 minutes I have
124/60= 2 hours
124%60 = 4 minutes
and so on for the days and the months and the years
The units Im using are:
mm-> HH /24
HH-> MM /30
MM-> YY /12
But something is really wrong:
Does anyone have an idea what was happening?
Thanks a lot, guys
Your calculations are "really wrong" because in real life, months have anywhere between 28 and 31 days, so you cannot represent a large number of minutes as a "date" that uses variable measures for years and months.
On the assumption that as units of measure you want to use ...
Year = 360 days
month - 30 days
... you can calculate as follows:
That's also what your calculation shows. If something is "really wrong" with that, it's probably your expectation, which is based on the traditional 365.25 day year.
Maybe you want to edit your question and explain what you expect as the "really correct" result.
In Excel dates are fractional number of days from 31-Dec-1899 (date 0 is formatted as 0/1/1900). So why don't you just add your minutes (after dividing by (24*60) to convert to days) to the earliest valid date in EXCEL (1900-01-01) and use the TEXT function to format:
=DATEVALUE("1900-01-01")+(21/24/60)-1
The bold part is your minutes.
This is now a proper EXCEL date; you can use TEXT function to format it into any way you like, or you can use DAY(), HOUR(), etc. functions to extract parts.
Having said that I don't know what your minutes represent; What date does Full Time in Minutes:21 correspond to?
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" ))
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).
I am doing some work in Excel and am running into a bit of a problem. The instruments I am working with save the date and the time of the measurements and I can read this data into Excel with the following format:
A B
1 Date: Time:
2 12/11/12 2:36:25
3 12/12/12 1:46:14
What I am looking to do is find the difference in the two date/time stamps in mins so that I can create a decay curve from the data. So In Excel, I am looking to Make this (if the number of mins in this example is wrong I just calculated it by hand quickly):
A B C
1 Date: Time: Time Elapsed (Minutes)
2 12/11/12 2:36:25 -
3 12/12/12 1:46:14 1436.82
I Have looked around for a bit and found several methods for the difference in time but they always assume that the dates are the same. I exaggerated the time between my measurements some but that roll over of days is what is causing me grief. Any suggestions or hints as to how to go about this would be great. Even If I could find the difference between the date and times in hrs or days in a decimal format, I could just multiple by a constant to get my answer. Please note, I do have experience with programming and Excel but please explain in details. I sometimes get lost in steps.
time and date are both stored as numerical, decimal values (floating point actually). Dates are the whole numbers and time is the decimal part (1/24 = 1 hour, 1/24*1/60 is one minute etc...)
Date-time difference is calculated as:
date2-date1
time2-time1
which will give you the answer in days, now multiply by 24 (hours in day) and then by 60 (minutes in hour) and you are there:
time elapsed = ((date2-date1) + (time2-time1)) * 24 * 60
or
C3 = ((A3-A2)+(B3-B2))*24*60
To add a bit more perspective, Excel stores date and times as serial numbers.
Here is a Reference material to read up.
I would suggest you to use the following:
Combine date to it's time and then do the difference. So it will not cause you any issues of next day or anything.
Please refer to the image with calculations. You may leave your total minutes cell as general or number format.
MS EXCEL Article: Calculate the difference between two times
Example as per this article
Neat way to do this is:
=MOD(end-start,1)*24
where start and end are formatted as "09:00" and "17:00"
Midnight shift
If start and end time are on the same day the MOD function does not affect anything. If the end time crosses midnight, and the end is earlier then start (say you start 23PM and finish 1AM, so result is 2 hours), the MOD function flips the sign of the difference.
Note that this formula calculates the difference between two times (actually two dates) as decimal value. If you want to see the result as time, display the result as time (ctrl+shift+2).
https://exceljet.net/formula/time-difference-in-hours-as-decimal-value
get n day between two dates, by using days360 function =days360(dateA,dateB)
find minute with this formula using timeA as reference =(timeB-$timeA+n*"24:00")*1440
voila you get minutes between two time and dates
I think =TEXT(<cellA> - <cellB>; "[h]:mm:ss") is a more concise answer. This way, you can have your column as a datetime.
I I'm have small headache caused today by excel and the way it takes control of everything. I have two time values I need to add together then divide by a value I got charged for that time to work out how much it cost me an hour.
so say I was charged day on for 12:30:00
on day 2 I was charged for 13:20:00
and day 3 I was charged for 20:30:00
In total it cost me £1000
The calculation would be
£1000 / (12:30:00 + 13:20:00 + 20:30:00 = 46:20:00)
I would guess to get the answer I would
1000 / Sum(12:30:00+13:20:00+20:30:00) = price per hour
But it doesn't...
I guess I need some sort of convert function on the time or to divide it by 24 to get hours but I'm stuck
Help would be hugely appreciated!
Excel represents times as fractional days, so your function is actually representing the rate per day.
Assuming your times are in cells A1:A3, you can adjust your function to something like:
1000 / Sum(A1:A3) / 24
which will give you the rate per hour (by my calculations, £21.58/hr).
As others have mentioned, you will need to set the cell to a currency format.
Excel should be performing the calculation correctly, but it is just showing as a time. Format the result cell as "number" instead.
You can use the HOUR and MINUTE functions to get the hour and minute portions of the time values, however as lc mentions, you do need to ensure that the formatting of the cell is set to Number, as it will default to a time.
Assuming you have your hh:mm:ss values running down the page (column A), in the next column put the formula
=(A1-INT(A1))*24
underneath this you can put your formula
= 1000 / SUM(A1:A3)
but don't forget to format it as Number.
