Tracking Date And Time Overlaps
Jun 18, 2008
I'm trying to figure out a formula that would track a student's class schedule to see if there is a date/time conflict. I'm uploading an example of a ficticious student named Amanda for you to review.
According to the example, I should be prompted that there's a conflict between Amanda's first two classes because they both meet on Monday (M) and Wednesday (W) and the time during each of those classes overlaps.
This will need to be checked per student, based on their ID in column A.

I have an assignment to audit the time it takes convert a printing press from one job to the next. I've been using a watch to take the readings in hours, minutes, and seconds.
I recorded them in my spreadsheet, as h:mm:ss, but it showed a date also. I think I finally got that resolved, but now, when I try to subtract one time from another time, I get an incorrect answer. I think I need to convert all of these times into decimals, as in 13.23.44, as oppossed to 13:23:44.
One post on page 1 of my search said to multiple A1*24, but I don't fully understand. I tried that, but 11:30 became 11.50?
I need to extract the set up time, or job to job changover time in a decimal format if possible. There are other tasks being done with those numbers later in the spreadsheet that are more conducive to decimals, than the time format.......

i work dispatch at a company and we're trying to track how long it takes for a technician to arrive on-site. my worksheet currently includes the date of call-in (E1) , time of call-in (F1), Service Date (G1), Service Time (H1), among many other field. the easy solution is to use the formula (G1+H1)-(E1+F1), and use the answer as the total amount of time, but the problem is if a customer call in at 3:00 PM and we service them at 9:00 AM the following day, it looks like it took 18 hours to arrive on-site, when in reality, since we close at 5:00 PM and open at 9:00 AM, we only took 2 hours to arrive on-site. is there any formula i can write to account for non-business hours and weekends, or is this a bit above what i should expect from excel?

how to calculate time overlaps between two ranges using a MIN/MAX formula. Now I need to do the same, but for three (or more) ranges. I have searched and searched, but I can't find a solution. I've attached a sample spreadsheet.
In the example, John is working three jobs, job one from 8AM-4PM, job two from 12PM-2PM and job three from 9AM-11AM. There is a total of 4 hours of overlap, 2 hours from job two and 2 hours from job three. How can I get Excel to calculate that for me?

At my new job the CHT/CRT that we receive is three days behind what we are actually using. It makes it hard for me to keep track of my talk time, so I thought I'd use excel to track it. I can see the time I have been on each call through the day. I had to put it in 0:0:0 format to get it to average correctly. (I was trying to get it down to just seconds but that seems a bit complicated. I just then used "average=(a1:a30)" to average them together and it seemed to work a bit.

I have a project with over 600 steps which we are trying to track when each part progresses by having 52 weekly columns. Their are 8 users which we have allocated a colour so when they complete one of the steps they select which step they have completed and which colour they are. This works well but I would like to put the date that the change was made in a separate cell in that row.
My question is can this be done with a formula as I am in favour of doing this as soon as someone changes a cell in the week range. If not I will need to nut through a VBA sub routine.
I know that this formaul does not work but it is along the lines of what I am testing for: =if(sum(T55:BM55)>" ",Date(),0) where if any of the cells in the range T55 to BM55 have any value or letter in them then put todays date in cell L55 else do nothing.

I have one series on my chart set as column type with data value labels. I have another series as line type to create a benchmark line across the chart. The chart is interactive where user can select 1 of 20 units.
On some of the units, the labels are overlapping the line type chart and causing a poor display

I have charts that needs to be placed on specific position and have specific sizes on a chartsheet. I use chartobjects(i).plotarea (top, left, width, height) for that.
Unfortunately when I set these values they still change and get antoher value, there is some scaling going on in Excel and I do not know where that comes from. I have been looking on the internet and finally I found a piece of code which works, but still not good enough, because the legend is also not good positioned.
De data for resizing the charts (ChtNew), the legends and the charttitle I get from other charts (ChtOrig). The legend.legendposition of ChtOrig does not have a value but it still have a top,left,height en width which I use.
I show you my code, the part with the for-next is taken from the internet.
With ChtNew.legend
.Top = ChtOrig.Legend.Top
.Height = ChtOrig.Legend.Height
.Left = ChtOrig.Legend.Left
.Width = ChtOrig.Legend.Width '* 1.1
.Top = ChtOrig.Legend.Top + ChtOrig.ChartTitle.Top
End With

I am attempting to pick up a date with time entry on a worksheet and place it into a TextBox on a UserForm. Format on the sheet is mm/dd/yyyy h:mm AM/PM. The UserForm is placing the value as mm/dd/yyyy 12:00 AM. here is the
Private Sub UserForm_Initialize()
If Not Range("dDate").Value = "" Then
TextBox2.Value = Range("dDate").Value
TextBox2.Text = Format(DateValue(TextBox2.Text), "mm/dd/yy h:mm AM/PM")
Else
TextBox2.Value = ""
TextBox2.SetFocus
End If
End Sub
"dDate" is the named range where the date is sitting. The format is also set on the TextBox2 exit event. Can anyone see why only the date portion is being transfered with the default 12:00 AM for no time component of the value?

I have loaded a .csv file in which the first column contains date/times, e.g. 01/12/2012 00:00. How do I now tell Excel (2010) that this is in fact a date/time format? If I select one or more of the cells, click on the Number dialog box launcher and try to pick a suitable format tghe cells resolutely refuse to budge from being text (i.e. left-justified, still allows me to edit the 'seconds' component to a number > 60). Also which data type should I be using? The only one that appears to have a full date/time format listed is Custom (not Date or Time).

I have a column of values resulting from subtracting a static date and time from the current date and time.
This means it is constantly updating, which makes it impossible to sort.
All my work depends on sorting those values, though.

I import data from a program that exports dates and times as text. I have been successful using "text to columns" to separate the time from the date and then using =text(A1,"00:00")+0 to get the time to show as serial time but I'd love to be able to do the whole date/time string in one step. In cell A1 there is data that is general format and is in this format:
01/01/13 00001
No matter how you try to format it, it is not a date or time. For this project I need the serial number for the date/time. Any formula that will format it as date/time and then allow it to show as a serial date/time?

I am using Excel 2013. Anyway, the first issue is that I need to pull a date and a time period from text. So, for example, if I see something like Sunday Prime Time 7/6/14 8:37PM, I would want to pull ONLY the "7/6/14 8:37PM" out of it. Each text box could potentially be different, so it might not always be in the same format as "Sunday Prime Time 7/6/14 8:37PM" it might only show just the date and/or the time without all the extra text i.e. 7/6/14 8:37PM. Some of the cells will have text, others might only have just the time or even just the date and the time. The only thing that I am worrying about in each cell is extracting just the date and time. If this is too much to ask of excel, I would be ok with extracting ONLY the time - 8:37PM and not the date, but I would much rather be able to get both the time and date.
THEN, onto part two of my question. After I would pull the dates and times, I need to compare them with each other. So, when I have the same date with two separate times on that date, I need to write a formula to show if those times on that date are less than 30 minutes apart. So, if I have 6 times on 7/6/14, I need to know if any of them are less than 30 minutes apart.
I would need to have the formula say something like "Problem" if the times on 7/6/14 would be 5:30PM, 5:48PM, 7:00PM, 8:00PM, 8:15PM, and 9:00Pm for example. I would like to see the word "Problem" since 5:30PM and 5:48Pm is only 18 minutes apart, and "Problem" after 8:15PM since that is only 15 minutes past the 8:00PM which is obviously under 30 minutes. The times that are more than 30 minutes apart such as 7:00PM and 9:00PM for example are more than 30 minutes apart from any of the other times that were extracted.

I'm trying to write a VBA code for converting the date/time as text to a date/time value.
The scenario is, I have three different types of text :
ddmmmyy
HH:MM

I could have the code working fine with the first two types, but not the last one.

I have a sheet with a list of dates in it that I wish to format to show the day as well as date and time. I am trying to do this automatically with a macro, below is the before and the desired after.
Before
Format - dd/mm/yyyy hh:mm
Appearance - 29/03/2009 00:30
After
Format - ddd dd/mm/yyyy hh:mm
Appearance - Sun 29/03/2009 00:30
This works fine when I format the cells manually, but when I try to format them via macro '29/03/2009 00:30' becomes 'Sun 29/03/2009 12:30' which is obviously a totally different time! Has anyone got ay idea why it might be doing this?

Consider this code:
'light eligibility
Dim facb As String
Dim sunset As Variant
[color=green]' check if facility has lights[color]
facb = WorksheetFunction.VLookup(RID, ds, 10, False) 'find facility code
If WorksheetFunction.VLookup(facb, fac, 6, False) = "Y" Then 'facility has lights
sunset = WorksheetFunction.VLookup(tempws.Range("A9"), sun, 2, False) 'lookup the sunset time based on the record's date
[Code] ......
This code checks the need for lights at a facility.
It first checks to see if the facility even has lights by cross-referencing a value in the record with a facilities database.
If it has lights, it then checks to see if they are needed. If the rental goes past the sunset time, then it needs lights. Sunset is determined by cross-referencing the date value in sheet1! A9, with the sunset database.
If it needs lights, variable lghtson is calculated equal to "sunset"-30 minutes.
As I step through this code:
WorksheetFunction.VLookup(facb, fac, 6, False) = "Y" Facility has lights.
Check to see if lights are needed.
sunset = WorksheetFunction.VLookup(tempws.Range("A9"), sun, 2, False)
sunset=0.879166666666667 which is 9:06PM. This is a proper value from the lookup.
If rental_end.value > sunset Then
rental_end (value from textbox) = "9:30 pm" , sunset=0.879166666666667. This is true, and Excel accepts it as true ...
lghtson = sunset - 0.5
0.379166666666667 = 0.879166666666667 - 0.5 (9:06 AM)
This is not the value I was looking for. I was looking for 8:34PM (0.856944444444444)

I have a time column (A) that when looked in the cell only shows AM & PM times, but the cell itself (not showing) contains dates too, keeping me from be able to do a sheet wide sort of time or time frame occurrences.
Can I do some thing to sort these cells with their corresponding rows based on time only disregarding dates?
I am trying sort out all rows that in column (A) is time equal to or greater than 4:00 PM OR even maybe sort all rows that column (A) shows a time between 4:00 PM & 7:00 PM. The date in the cell is the problem, I think. Excel 2013

I want to add hours to a date-time cell to get result in date-time.
Format of cell A1 is d/m/yy h:mm AM/PM
Format of cell A2 is General
Format of cell A3 is d/m/yy h:mm AM/PM
I want to add A2 (number of hours) to A1 to give A3.
The formula I used is A3=A1+Time(A2,0,0)
The formula works perfectly fine when A2 is less than 24, but when A2 is more than 24, the date doesn't get changed.
