Delete Date & Time Cells Based On Time
Dec 6, 2006
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? .......

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've attached an example workbook.
Trip Plan example.xlsx
I'm trying to work out how to have cells R11 - Rxx generate the correct date, based on the rest of the calculations.
Please note that the attached is a crude cut down version of the larger spreadsheet, for the purpose of highlighting my problem.
SO, if E7 is changed, subsequently the values in K11:Rxx will be respectively updated.
D12 and G12 are entered manually. (although I'll probably make these drop downs or date choosers at some point...)
Depending on the value in E7 and time in D12, the required break period is listed in K11: Kxx.
The time that these periods of rest are required to occur before is then calculated and listed in O11:Oxx.
I need R11:Rxx to calculated the appropriate date from these calculations, relative to the date in G12.
For example, the rest required in K11, is required on the same day, as such it need to populate with the value in G12.
However the rest required in K13:Kxx, is required by a time (O13:Oxx) on the following day - G12+1
In some case, this time variance could run over 2 or more days.
I figure it's got something to do with the value in D12 also including the date of 0/1/1900.
I'm happy to add hidden cells for formulas/results to work around it, as the end product will print as an A4 document, where many cells will be locked.
Would prefer not go with any VBA unless it's my only option as I haven't done any VBA stuff as yet.
NB (the value in P5 is static only in this example)

Is it possible to be able to select a range of dates, and a time interval, and then to automatically fill in cells in a column? to be more specific, I want to be able to select, say 1 Jan 2013 to 31 dec 2013 in one box, then specify a time interval, for example "hourly" and then a column is populated with each interval, i.e. 1 jan 2013 00:00, and then the next one is 1 jan 2013 01:00 etc. I have tired the normal automatic fill tool but it never seems to get it right. It works for the first few days then it all goes funny.

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).

how to delete rows when a combinations of 2 cells in a row will repeat.
Example:
Row 1 51456264 150

I have a spreadsheet with date and time values of the format
"dd/mm/yyyy hh:mm" in column A followed by some other data in cells of that row.
What I'd like to do is have a macro that will delete a complete row if the time value in column A lies between two times that I can specify in the macro (the dates are irrelvant)

I have a UserForm which writes data to rows in a master spreadsheet. I'm attempting to write some vba code for a CommandButton in the master spreadsheet which can identify and delete duplicate entries based on "user ID", "Date", and "Time". I would like the CommandButton to retain the most recent entry from a user and delete all previous entries.
My master sheet is set out as such...
A, B, C, D,
UserID, Date, Time, Response
The users could potentially submit multiple entries on the same day. Ideally I would like to be able to click a CommandButton and delete each user's submission but retain their most recent one (based on "UserID", then "Date", then "Time").
I've searched all day for a solution and I've come close but I can not figure out a code that accounts for my three variables ("UserID", then "Date", then "Time").

I have a workbook with macro button to run some vba, if i want the button to disable when the user make copies of the workbook (date created is later than original wb saved time) what codes to add in the VBA?
what i assume is to add the time to a cell when the wb is saved, when the wb opens, it check for that cell if the same with the date created, if different, then disable the macro button.

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 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 have one column with as many as 50,000 or more rows. The data format for each row/ cell is unique as shown below ( date and time). I wanted to split the data as shown in "Formatted Data" below. Have Tried Text To Column formatting but didn't work right.
Raw Data: Formatted Data (2 cells):
2005/11/02 23:55:15.758 ==> 2005/11/02 23:55:15.758

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.

I need a formula to add just the time to ' date and time', ignoring weekends.
eg:
Fri 24-Aug-07 10:52 is the date and time
28:48:00 is the time
If I add the time to 'date and time', result is coming as Sat 25-Aug-07 15:40
But it should come as Mon 27-Aug-07 15:40 (hence ignoring weekend)

I have a problem regarding sorting data having date and also time within a single cell.
Example data (I have written it as code to preserve formatting)
A B C D E F
12/5/2008 02:072/5/2008 06:0128804833363
22/5/2008 18:012/5/2008 18:0599271297
Column B is start date and time whereas Column C is end date and time.
My aim is to cut and paste the whole row automatically to Sheet2 if the time is within 2AM to 8AM else leave as it is.Also I don't know anything about VBA Script.

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 know the title is a bit vague, but I cant think how else to word it!
I have a sheet (attached) which works out hours worked, and if the amount is under a specified target, it counts how much time is owed. The problem occurs when someone works more hours than the specified target.
I guess I need an IF formula of some kind, to say if the figure is over the target, to put zero in the hours owed column.

I have the a file that is downloaded from AS400. The time column is presented in 24 hours format in column D. For example : 92114 means 9.21 am. I need a formula to adjust the date in column B based on the following criteria:
1) If the time is after 2.00 pm, adjust to the next working day taking into account public holidays in column H
2) If the time is before 2.00 pm, remain the same day
3) if the time is after 2.00 pm and it is Friday, adjust to the next working day taking into account public holidays in column H
The correctly adjusted date is in column E.
