# Time Calculation ...

Jun 4, 2009
Having been looking round this site for quite some time now and always finding what I needed I am now a registered member who needs your expertise.

I have a spreadsheet for which I need to calculate hours worked depending on a few criteria.

[data] ...

The criteria is that Sat/Eve is 8pm to 6am weekdays and midnight to midnight on a saturday. Sun is midnight to midnight on a sunday, BH is a bank holiday and basic is everthing else. What I want to know is it these columns can be populated automatically using formulas.

I would really appreciate it if someone out there is up to completing this challange, as I have to manually populate this at the moment and it can be 5000+ lines long (it takes hours). If i need to change the layout it's not a problem, whatever it takes to automate it has got to be worth the effort.

I have 4 distinct columns.

Adm Date Adm Time Trans Date Trans Time

1/16/2014 937 1/16/2014 1045

1/1/2014 121 1/1/2014 121

1/14/2014 800 1/11/2014 735

1/30/2014 100 1/30/2014 205

1/13/2014 800 1/12/2014 1202

I would like to calculate the difference (# hours spanned from the dates shown). Unfortunately when we transfer the data the COLON is dropped from MILITARY TIME so I am having problems in the calculation. This is also made more difficult as some of the calculates span over two dates.

Need a point in the right direction with this one! I want to calculate the difference between two time values, the problem is there two different formats as below:-

1) 520.00 - this is a number format

2) 500:00:00 - this is a time format HHH MM SS

What could I use to show I have a 20.00 hour difference???

I have been burning brain cells trying to figure this out.

I get these numbers from an online source and they come in like this:

A B C D E

1/1/0912:01AM02:40AM11:18AM07:55PM

The times do not come in as times...when I format the cell to time it doesnt change...that is my first problem.

What I would need to do to these times is: take B and C and find what time is in the middle of them and put that in a different column.

This mess will also need to be plotted on a chart with time by the minute for one day as the X axis. In my example I drew lines on the chart to show what I mean....the blue lines I dont want charted...I use those to find the time in the middle.

I am trying to get a total column that will give the total only when two particular devices are down at the same time. This total will be taken from a long list of downtime entries for different devices but I only want the total when two particular devices are down, for example

Devicedatedowntimedateuptimetotal time

102/01/0911:00:0002/01/0911:09:0000:09:00

202/01/0911:00:0002/01/0911:04:0000:04:00

202/01/0902/01/09

103/01/0903/01/09

303/01/0903/01/09

604/01/0904/01/09

204/01/0913:09:0004/01/0913:12:0000:03:00

104/01/0913:02:0004/01/0913:15:0000:13:00

505/02/0905/02/09

total 1/200:07:00

In the example I am just wanting to work out the total time when both device 1 and 2 were down at the same time, above the total would be 7 minutes because for 4 minutes on the 2/1/9 and 3 minutes on the 4/1/9 they were down at the same time.

I have a time card sheet that I want to make automatically calculate the time I have worked. It is set up with four columns that can't be changed. The first column is "Time In(TI)", second column "Time Out(TO)", Third column "Time Taken For Lunch(TTFL)", and Finally "Hours Worked". I have no problem getting the formula to calculate the difference in "Time In" and "Time Out" but taking the 30 minutes out of that is causing a rift. If I put the 30 minutes in 00:30:00 format it will take it but it thinks it's 12:30:00 and it displays in 00:30:00 which I want it to display 30. Just to clarify, I am using =(TI-TO)-TTFL in the Hours Worked cell.

I am a big fan of huge files (30MB+) all interlinked with array formulas ...and lots of them. The problem is...one calculation take literally 5 hours. (I have one file I try to calculate since cca 4 hours now...it's at 63%)

I keep getting extra memory with no visible improvement on the processing time. Is there a trick out there that I can use? Something is clearly wrong.

I feel I will soon have to give up Excel, or my formulas, or my job ...

I have a calculation whereby I use two variables which are 1. Man hours left in the week formatted as [hh] and 2. Amount of work left to do in the week formatted as 0" Man Hrs" I need to carry out a calc which says:- Man hours left in the week - Amount of work left to do in the week.

The answer should tell me if I have a deficit or surplus of hours which can then use for planning purposes. Unfortunately the problem I have is that I can't make the formatting the same for both unless someone knows of a workaround.

Man hours left in the week = 128. Man hours required to complete all work this week = 224. Therefore I need to say 128-224 = -96. However when I do this this an answer of 16 is returned.

I have attached excel sheet. Column A consists of List of LAN numbers, Column B consists of List of Documents tagged & Column C consists of time at which particular document is tagged.

I need to calculate the time taken to tag all the documents in Lan1/Lan2/Lan3 in Column D. (I can ignore the date by doing text to columns).

[code] ......

=SUMIF($A:$A,">="&TODAY()-1,D:D)-SUMIF($A:$A,">"&TODAY(),D:D) calculates the total in Col D looking back from today. The results gives you 12:00. What I need is a formula that will look back from the current time to 24 hours in the past, NOT 1 day, to calculate the total in Col D. Looking back 24 hours, from 10:00am, the results would be 6:00.

Since the first time on 12/12 has not arrive, it will not calculate it, but will look back from 10:00am on 12/12 to 10:00am on 12/11 and calculate a result of 6:00 hours.

I am trying to calculate the response time between when a phone call comes into my workplace and when the responder calls back...I have created a formula that does this using the times and dates of when the calls were recieved and went back out. This works except when the call comes in on one day and goes back later in the day the next day, making the response time larger than 24 hours. I also have it set up to eliminate 15 and a half hours from the calculation because our place of business is not open during this time. Further details....

The formula currently being used is... =IF(G50=E50, H50-F50+(H50

I need to find out the total time an issue was 'open' (not resolved) during business hours. Issues come in and resolution time is based off of a priority. Priority 1 should be resolved in one hour, Priority 2 should be resolved in 4 hours, Priority 3 should be resolved in 1 business day (8 hrs), Priority 4 should be resolved in 2 business days (16 hrs), Priority 5 should be resolved in 5 business days (40 hrs), Priority 6 should be resolved in 10 business days (80 hours).

I have start dates/times field in a column (mm/dd/yyyy hh:mm) , a resolution dates/times field in another column (mm/dd/yyyy hh:mm) and a priority in another column (1-6). I need to calculate the time an issue is in open status (not resolved) based on it's priority but I need for it to take into consideration business hours (Monday thru Friday...7 am to 7 pm)...and not calculate time outside of 'business hours'.

I'm attempting to calculate the total number of hours between a start time and end time using textboxes on a Userform.

Here is my latest attempt:

Private Sub D24_Exit(ByVal Cancel As MSForms.ReturnBoolean)

Dim myvalue As String

Dim myhour As String

Dim myminutes As String

myvalue = D24.Value

Select Case Len(D24)

Case 1

myhour = "0" & Mid(myvalue, 1, 1)

myminutes = "00"

Case 2

myhour = Mid(myvalue, 1, 2)

myminutes = "00"

Case 3

The above codes are an attempt to force an entry as time (7, 07, 700, 0700=7:00 / 13, 1300=13:00 etc.). However, the result is not correct.

For example:

Start Time in Textbox(D24)=07:00

End Time in Textbox(D25)=17:30

Result in Textbox(D27)=0.4375

Desired Result in Textbox(D27)=10.5

I've never calculated times in textboxes,

I am trying to calculate the time spent on each task.

I have column A with Task IDs and column B with Time. Column A could have the same task ID repeated but the column B has the time for each entry. There is only start time for each task.

Where the Task is repeated, want to know how many times the task has taken place and overall time spend on one task ID, calculating from the first entry to the last entry.

I've got a CSV file that has been sent to me where each entry has a vehicle reports in with certain metrics. Included in these metrics are the time the metric is reported. The problem I am having is that the time is delivered in UTC date/time (in Column A). Column B has an "offset" to show how many hours difference there are between the UTC time and the local time for that particular vehicle.

Problem 1 - My initial thought was to use "Text to Columns" with space as the delimiter, thinking I could just run a simple subtraction formula once completed. The problem here is that if an entry is recorded after 7pm local time, the UTC time moves into the next day, and the simple subtraction formula will not take that into account.

Problem 2 - Even if there was a workaround, it seems that the numbers in the "Offset" column don't work well with time calculations because they are not a time (it's -5, -6, -7, or -8).

I want to calculate % increase with time related fields

Field A1 = 01:53 (formatted custom as mm:ss) happy to format some other way

Field A2 = 02:08 as above

I want to know the % increase. The correct answer is 13.27% , as 01:53 = 113 seconds and 02:08 is 128 seconds and 128/113 = 1.1327 so 13.27%

I am trying to figure out a formula to figure out how much to charge for hrs of a rental. There is an automatic $1000 charge regardless of time used. the rate chart is as follows:

$1000 + hourly charge = total

=<50 hrs= $15/hr

>50hrs but <100hrs= $6.50/hr

>100hrs=$4.10/hr

ex: so is A1= 200hrs then i want B1 to equal $1820.($1000 + (200 x 4.1))=1820.

I have an idea on how to write the formula, but i am having a little bit of trouble with it.

I am struggling with the calculation of time in excel and cannot find a reliable solution for it using formulas. The reason is, excel does not display negative time values, unless one formats the results as text. This is no good, as I need to add up those results and that's something excel cannot do with values formatted as text.

Therefore I am aiming to do just that by using a macro. The values in columns I & J should simply be converted and pasted into columns U and V respectively (see attachment). For example 200 minutes should appear as 03:20 [hh:mm]. Accordingly, -200 minutes = -03:20 [hh:mm]

How to calculate time spent at an area.

Currently i have in two columns the arrive time and then the depart time. i need to work out how long was spent at the place e.g(10:00am arrive - 11:25 depart time which gives me 1 hour 25 minutes at the point) from there i then need to subtract 1 hour from the 1 hour 25 minutes and then multiply the remaining time (25minutes) by 65

This will then give me the answer 27.08

how to further formulate wages calculation.

I made a time sheet which calculates number of hours worked and so on. Now I would like it to calculate the wages as well. The problem is that there is a higher payment for nights.

- $16 per hour on regular hours

- $24 per hour from 23:00 to 07:00

How can I formulate it that I get the total payment taking into consideration nights?

I was looking for a solution through the excel questions but could not find anything which would help me.

As you can see in column B are two different colored Sun, red and magenta as well as Mon and Tue.

I would like to find a formula or macro without creating an extra column which looks for the color magenta i.e. if the particular cells are magenta (Sun, Mon and Tue) then perform an action.

I cannot use the formula in K7.

I work with a lot of time based worksheets for a 24/7 operation and constantly use the formula:

=IF($E17>$D17,(HOUR($E17)+(MINUTE($E17)/60))-(HOUR($D17)+(MINUTE($D17)/60)),((HOUR($E17)+24)+(MINUTE($E17)/60))-(HOUR($D17)+(MINUTE($D17)/60)))

to calculate times worked where $D17 is start time and $E17 is finish time. Shifts can start and finish the same day ($E17>$D17) or go past midnight ($D17>$E17).

To make matters even more interesting, there are a number of variables that require adding either "and" and/or "or" conditions to this formula so I can end up with several of these nested and it gets pretty complicated.

I'd like to have a UDF so I can just enter the formula:

=CalcTime(Start Time,Finish Time)

I am working on a project involving calculating time. It is a timesheet calculation. I was able to design the following layout:

.....A............B..........C..........D.......E.....F

1....Date.........Time IN....Time OUT...Hours... Total

2....01/01/07.....1830.......1930.......01:00...01:00

3....01/02/07.....1930.......2330.......04:00...05:00

4....01/03/07......830.......1900.......10:30...15:30

5

Column A is formatted for DATE. Columns B and C are GENERAL. Columns D and E are DATE format customized as '[hh]:mm'

The formula to calculate the time difference between the numbers in column B and C is located in column D. It is as follows:

=IF(C4<1000,TIMEVALUE(LEFT(C4,1)&":"&RIGHT(C4,2)),TIMEVALUE(LEFT(C4,2)&":"&RIGHT(C4,2)))-IF(B4<1000,TIMEVALUE(LEFT(B4,1)&":"&RIGHT(B4,2)),TIMEVALUE(LEFT(B4,2)&":"&RIGHT(B4,2)))..................

I have a rather large spreadsheet that takes a long time to calculate. One sheet has the data (about 2800 rows by 650 columns), with samples in rows and data for each sample in the columns. A second sheet has functions to group the data according to predefined patterns. That second spreadsheet is about 800 columns wide and as many rows as I need it to be, as the samples don't need to be analyzed all at once.

Ideally I would like to do all samples at once by making the second spreadsheet 2800 rows high, but the calculation time is just way too long. And there's the problem. The calculation time seems to increase exponentially with the number of rows I calculate at a time. I ran a few tests making it different sizes, and here are the results:

rows

time(seconds)

100

3.5

150

12

200

23

[Code]...

I tried both HLOOKUP and INDEX/MATCH functions and it didn't make a lot of difference. These numbers are for INDEX/MATCH.

Graphing these numbers show that it follows an exponential curve pretty closely. What is interesting is that the progress indicator at the bottom of the screen finishes in a few seconds, about 5 seconds for 350 rows, and I can see the new data after those few seconds. But then it sits and appears to do nothing for the rest of the time. So, for 350 rows, it looks to be done with the calculations within 5 seconds, but then it freezes for another 2 minutes with CPU usage maxed out before I can do anything with the program. That actual calculation time seems to scale linearly with the number of rows I calculate, but the time after it finishes calculating before it finishes whatever else it's doing scales exponentially.

The spreadsheet does have a macro and a couple of other sheets and a macro that do some later analysis and I wondered if that had something to do with it. To check that, I created a new spreadsheet and set it up the same as the original one, with the data in one spreadsheet and the INDEX/MATCH formulas in the other. I copied the data over, but setup the formulas new without copying/pasting anything. It didn't make any real difference.
