Time Calculation ...

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.

Calculation Of Time With Two Different Time Formats
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???

Calculation On Time
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:


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.

Same Time Calculation
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
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.

Time Calculation
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.

Calculation Of Time Formula
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

Variable Time Calculation
[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.

Time Spent Calculation
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'.

How Do I Reduce Calculation Time
I am a big fan of huge files (30MB+) all interlinked with array formulas ...and lots of them. The problem calculation take literally 5 hours. (I have one file I try to calculate since cca 4 hours'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 ...

Formatting With Time Calculation
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.

Textbox Time Calculation
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,

Time Calculation With Colored Cells
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.

Converting Long Time Calculation To UDF
I work with a lot of time based worksheets for a 24/7 operation and constantly use the formula:


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)

Calculation Time And Charge Rates
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

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.

Time Calculation: Calculate How Many Hours Have Elapsed Between To Entries
I am trying to build a spreadsheet to calculate how many hours have elapsed between to entries; start time (H10) e.g. 9:15 AM and end time (I10) e.g. 12:15 PM. The formula that I am using in the calculation cell field (J10) is (I10-H10+(I10<H10))*24. This formula works great till I wish to include in an IF statement. What I would like is if the total hours calculated with the formula (I10-H10+(I10<H10))*24 is less than 4, return 4 (hours) otherwise the value. As well if there is no start time nor end time entered then return zero.

Add This Number To The Start Time, Factor In Break Minutes And Get To The Projected Completion Time

So after entering the variables I used =(((C3*4)/60)/D3) to come up with the time needed to process the orders. What I can't get to is how to add this number to the start time, factor in break minutes and get to the projected completion time. I have Excel 2003 at work. Clearly I need to take a class!

Automatically Change Cell (With Time) Color After Time Period Has Passed
I have a protected worksheet. Users wish to be able to track changes in the input cells. The suggested approach for this is to temporarily disable sheet protection and allow them to change the font color, then protect afterwards. What I would like to do is:

i) check whether they are in an input cell
ii) if so, then prompt the user with the 'Font Color' dialog box
iii) apply the font color selected to the input cell

I'm struggling to find the dialog box I need. I can launch the one to change the interior color, no problem (Application.Dialogs(xlDialogPatterns).Show). But that's no use to me, I just want a color palette that specifically relates to the Font Color

Count Number Of Full Time Periods Within A Time Period
I have thousands of timestamps that have a start & end date and time in 2 separate columns. (one named start and one named end...)

I also have numerous set time periods that i'm interested in.. (about a dozen or so)

for example 01/01/2008 - 05/01/2008, 07:30:00 - 10:00:00

What i need is to be able to count the number of times the full time period i am interested (07:30:00 - 10:00:00) in falls in between the thousands of start and end timestamps i have. The time periods must also fall within the date range specifed.

So if my timestamps were
Start: 01/01/2008 06:30:00 & End: 02/01/2008 11:00:00, based on the set time period above, there would be a count of 2

and if my timestamps were
Start: 01/01/2008 07:05:00 & End: 02/01/2008 09:00:00 there would be a count of zero as there is not a full uninterupted timeperiod 07:00:00 - 10:00:00 between these timestamps.

and if my timestamps were:
Start 01/01/2007 07:00:00 & End 02/01/2007 10:00:00 the count would be zer as this is a year early!

Delete Date & Time Cells Based On Time
I have a large dataset where the first column is date and time i.e. "20/01/2005 03:41:06" and I want to delete certain rows based on the times. I have already tried playing about with macro's but failed fairly spectacularly so far. I have code from someone else to delete cells if the value equals a certain time but this doesn't work as the cell contains the date too.

I have already recorded one macro to reformat the data to as the software return 10 timestamped samples per hour and I want 8 i.e. every three hours so there is constant separation for statistical purposes. Both the macros are shown below so you can see what I have.

Ideally I would like to replace the line - If (r.Cells(n, 1) = TimeValue("22:41:06")) ............ - with one that reads - If (r.Cells(n, 1) CONTAINS TimeValue........ - but I don't know if that is possible? If not is there a way to separate the time from the date into 2 columns and then I can delete rows based on the time column using the code below? .......

I need a way to compare the time of the computer with the one in the cell and bring up a message box if the time matches.
Yet i don't want it to be a one time makro. What i want is to be able to work with the worksheet and that at the same time i want a paralel function to check whether the time in the cell matches. Something like agenda in Outlook.
