How to round time to nearest hour in Excel, for example:
67:45:00 will be 68:00:00
and
53:14:00 will be 53:00:00
regards
You can use MROUND function like this
=MROUND(A1,"1:00")
Assuming the time is in A1 this will round to closest hour.
=ROUND(A1*24,0)/24
Using ROUNDDOWN will force 67:45:00 to 67:00:00
Using ROUNDUP Will force 67:45:00 to 68:00:00
Same formula, change:
24 to 48 for half hours.
24 to 96 for quarters
If you are grouping hourly in a 24 hour span but the date is included in the time stamp, use the same formula but subtract the datevalue after:
=ROUNDDOWN(A1*24;0)/24-INT(A1)
This is useful if you want to see at what time of day something peaks over a period of time.
Transform it to hours (5h 15m = 5.25h) then round it
if you only have it as a string use
=if(round(mid(A1;4;2);0)>29;mid(A1;1;2)+1&":00:00";mid(A1;1;2)&":00:00")
i use round to convert the minutes into a number
I recently had to convert times to the nearest quarter hour. I used the following sequence of formulas, which seemed to work:
=SUM(A1*24*60) - this converts the time to minutes
=MOD(B1,15) - this finds the minutes since the last quarter hour
=IF(C1>7,15-C1,-C1) - minutes needed to round up or down to nearest quarter hour
=SUM(D1/(24*60)) - converts the adjustment needed from minutes back to a days
=SUM(A1+E1) - this is the original time adjusted up or down to the nearest quarter hour

I'm stuck with the time functions in Excel.
I have a table filled with a number of minutes. I can easly count the number of hours by dividing the number of minutes by 60. But this gives me a real number which I can't find how to translate into a duration. I find it easier to read 37h 36min than 37.6 hours.
what I have what I want
minutes hours
monday 2160 36 36:00
tuesday 2255 37.6 37:36
wednesday 1715 28.6 28:36
Note that when I apply the [h]:mm# format to the cells it does not work. I guess because my initial data is in real value and not in time format...
Excel stores time as fractions of a day.
There are 1440 minutes in a day (60*24)
So:
=TEXT(A2/1440,"[hh]:mm")
If you just want to format the cell, so as to have a numeric value rather than a text string, then use:
=A2/1440
and format that cell as [hh]:mm
Super late to the party but the TIME() function can be used
=TIME(FLOOR(A2/60,1),MOD(A2,60),0)
or
=TIME(ROUNDDOWN(A2/60,0),MOD(A2,60),0)
Looking for formula to determine how many of the time given between 14:00 to 22:00

You can subtract both datetimes and you'll get the amount of days. If you want it to be in seconds, you just need to multiply this by the amount of seconds within one day (60 seconds * 60 minutes * 24 hours), and obviously, don't forget to format your cell content as a simple number (the subtracting might cause a datetime formatting, which is not what you want).
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 have a column which has total machine hours of certain activity. For instance, I have values like followed,
Total Production Time
5:35:55
36:35:09
55:24:45
I couldn't perform any calculation with this column neither import the column into other tools because excel gets this fields has hh: mm: ss AM/PM format. Even if I change to this column into text it gives me some decimal value.
My ultimate aim to calculate total minutes [total hours]*60 + minutes or make this column as it is to import it to my tool where I can achieve the same
I wanted to convert this hour into minutes.
Excel sees date/time as the number of days since 1/1/1900. Time is a decimal fraction of a day.
So 12 hours is 0.5
To get the number of minutes you would multiply by 24 hours and 60 minutes:
=A1*24*60
This will return the number of minutes.
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.
