Changing Date/time To An Interval

Aug 29, 2008

I have a column that shows the date and time and it looks like this:
8/1/2008 6:36 AM
8/1/2008 11:15 PM
8/1/2008 8:01 PM
8/1/2008 3:12 AM

I want to convert it to show just the time but I want it to be in 30 minute increaments. So in the example above, I'd want to see this:
06:30
23:00
20:00
03:00

Fill In Date And Time Where Missing On 3 Minutes Interval

Jul 20, 2012

I am having trouble getting a VBA code to do the following:

2012/05/01 00:00:00
2012/05/01 00:03:00
2012/05/01 00:06:00
2012/05/01 00:15:00
2012/05/01 00:18:00

From this above to this below

2012/05/01 00:00:00
2012/05/01 00:03:00
2012/05/01 00:06:00
2012/05/01 00:09:00
2012/05/01 00:12:00
2012/05/01 00:15:00
2012/05/01 00:18:00

There are data entries next to these time stamps. I am able to create just the time stamps starting at the beginning and ending at the end of the month but I need it to fill in missing entries in a data set. The code below works but only some of the time. I have tried a few different things but nothing works.

Code:
Sub Insert_missing_3min()
'Inserts a row with the date and time where the missing date and time stamp is and a zero next to the date added.

Dim min3 As Date
Dim CurTime As Date
Dim CurCell As Date
Dim NextCell As Date

min3 = 3 / 24 / 60

Find Date / Time Entries Within 1 Hour Interval And Remove All But One Of Them

May 8, 2013

I have a large data set which contains four coloumns: Supplier, Supplier number, order number, and date/time of delivery. The date/time coloumn is formatted as YYYY-MM-DD HH:MM with a 24h time notation. What i want to do is to find deliveries that occurs within 1 hour and that are from the same supplier. So i basically want to group (?) the data with regards to the suppliers and then, within these subsets, check for date/time entries that occurs within 1 hour from each others by "reading" each date entry and compare it to the following one(s) (and maybe stop comparing when the 1 hour interval is passed)?

Furthermore, even if this one might be very hard, it would be good if i could make sure that the entries that are "tagged" as within a 1 hour interval, wont be used as basis for a new interval or be included in other intervals.

The result i am after would be number of 1 hour intervals for each supplier and the number of entries in each interval.

Below is an example from the date/time coloumn:

12-03-08 15:32
12-03-08 15:33 ... Interval with 2 entries
12-03-12 14:54
12-03-28 11:57
12-04-16 09:10
12-05-07 13:41
12-05-07 13:46 ... Interval with 2 entries
12-05-28 11:55
12-05-28 12:00
12-06-04 12:01 ... Interval with 2 entries
12-06-04 12:09
12-06-11 08:30
12-06-11 08:31
12-06-11 08:59 ... Interval with 3 entries
12-07-02 11:10

Autofill Changing Date And Time

Dec 7, 2013

I have to create a number of spreadsheets with changing dates / times / both.

This would be a fairly good example:

Add one day + 1 hour for 31 days of a month.
"01/01/2014 01:10"
"02/01/2014 02:10"
"03/01/2014 03:10"
"04/01/2014 04:10"
"05/01/2014 05:10"
"06/01/2014 06:10"
"dd/mm/yyyy hh:mm"

The above format is important, and - it has to be in quotes.

Which, if necessary I will manually add using replace, but would prefer not to.

So I may then need to take the first date... lets say 06/12/2013 07:00 then, Add one day + 3 hrs 30 mins.... so as the days roll between 1 to 31 it is obviously going into the 24 hour clock, rolling argument.

And, to top that -

1. the csv then needs to be put into software (I assume it reads the data in the sheet and not the formulas).
2. I can't have extra columns as they would need to be deleted.

I have tried copying down, like a standard auto-fill but it always goes wrong.

Establishing A Time Interval

Sep 5, 2008

I have a list of times, and I need to work out a way to establish what time interval it applies to, using a function. In production, this will be used over hundreds of entries at a time, but for the sake of example I'll cut it down to 15 times:

17:28:35
16:11:14
17:08:20
19:21:51
15:29:01
15:31:45
14:32:24
13:39:51
15:44:41
16:52:38
20:17:37
13:26:05
15:45:01
20:12:24
12:53:26

Now, there are 27 different time intervals there times can fall into:

1: 6:00 - 6:30
2: 6:30 - 7:00
3: 7:00 - 7:30
4: 7:30 - 8:00
5: 8:00 - 8:30
6: 8:30 - 9:00
7: 9:00 - 9:30
8: 9:30 - 10:00
9: 10:00 - 10:30..............

So, what I'm looking for is a formula that will match up the time to the interval. For example, it would look at 16:52:38 and output that it falls within interval 20.

VBA Save File On Time Interval?

Oct 11, 2013

I have a file that sits open all the time, and performs some refresh functions every thirty minutes. I need the file to save a copy of the tab as a CSV file at a given time interval. The code below is almost there, just need to work with the time interval part. The way it should work is to open the csv, copy / paste the active sheet; then close the csv; leaving the original excel file open. I can run it, and it works, but the time interval is not triggering.

I can get the time interval to work by itself, and the save csv part to work by itself also; I need them to work together.

VB:
Sub test()
Application.OnTime Now + TimeSerial(0, 1, 0), "test"
Dim OutputFile As Workbook, InputFile As Workbook
Dim sDD As Worksheet

Auto Fill Non-changing Date&time When Cells Change

Apr 17, 2007

Let's say I have column C blank, but every time it's filled in with something I want column A to be today's date and B to be current time. Unfortunately, the functions NOW() and TODAY() don't give me what I want. They get recalculated every time that I update the spreadsheet.
Another thing that I can do is just press ctrl+shift+; to generate a non changing date/time, but I want it to happen automatically (being super lazy).

Is it possible to 'round' a time to the next nearest 15min interval?

As an example in cell A1 I have a value that returns 2:07 PM (its formated
as h:mm AM/PM), but in B1 I wish to translate this to the nearest 15min
interval in an hour which is 2:15 PM, if the value in A1 was 5:39 PM I would

Formula To Count Number Of Patients Per Time Interval Over 24 Hours+

Jan 23, 2014

I have been trying to work out a formula for capturing the number of patients in the hospital at half hour time intervals. There are a lot of formulas for capturing this information within a 24 hour period however not a lot of information when the Length of Stay or episode time is +24 hours.

As you can see in my example spreadsheet below, some of the patients stay for 244 hours (row 9).

The outcome that I am looking for is that a 1 is placed in all of the time slots when the patient is there. For example if they arrive on Jan 1st at 2.15 and leave on Jan 3rd at 10.30 all of the time slots in between would have a 1 placed in them.

I have been playing around a lot and think it is probably only possible if you set it up as I have in the example i.e. by having the date running down and the time running across.

How this could work? I have tried SUMIFs and SUMPRODUCT formulas which generally work for Jan 1st but then go wrong for any date after that.

Changing Date/time To Run A 12 Hour Production Schedule, And Not 24 Hour

Sep 4, 2006

I have created a daily schedule which has a number of factory variables taken into consideration which determine the date and time a particular product should, barring any mechanical problems, come off the machine. (see attached spreadsheet).

The date at the top will be editable by me only so that when I update the production quantities, the date/time off column automatically re-adjusts to the remaining quantities.

The formulas are a little long winded, but I have left them that way whilst I try and develop it. I should be able to figure out how to condense them later.

My problem is that the date/time off on the right works excellent, but over a 24 hr period.

Ordinarily, we work a 12 hour day (6am to 6pm) with overlapping shifts to cover breaks, and 20 mins warm up at the start of the day for the machine, thus maximising a 12 hour day.

Of course if demand exceeds the allotted time we put on overtime.

Is it possible to specify that normal days are only 12 hours so that if a product exceeds 6pm, it flows into the next day with the balance starting at 6:20am?

And, if the production for the week exceeds the time could I stipulate particular days which we deem are suitable for overtime? Ie, we decide Wednesday is a 14 hour day and not 12.

I had toyed with the idea of creating a 365 day table/calendar, on another worksheet which would have its individual allocated hours in an adjacent column and somehow link them to the date/time off, perhaps by way of a VLOOKUP, but I have been chasing my tail trying to figure out how to implement it.

Changing Elapsed Time Into Time As Portion Of An Hour

In A1 I have 35 min elapsed time and need to change it to time as a portion of an hour. It reads the 35 min as TIME, therefore I am currently using

=IF(A1>=0.5,A1-0.5,A1)*24. Output is .58, which is perfect.

(output column formatted as a number)

Likewise 3:28 becomes 3.47.

Date/Time Formula: Pick Up A Date With Time Entry On A Worksheet And Place It Into A TextBox On A UserForm

Jun 17, 2006

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?

Convert Imported Date / Time Data To Date / Time Format?

Jan 2, 2013

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).

Converting Text Date And Time To Serial Date And Time

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?

Excel 2013 :: Extract Date And Time Info From A Text Cell That Contains Text And Date And Time

Jul 19, 2014

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.

At the moment cells b1,b21,b41 are copied down as follows. =if(a1>0,TODAY(),"") This works fine, but the date stamp of course changes tomorrow. I can not apply code to the whole b column as cells b2:b20, b22:40 etc have other non-date format data to which the code does not need to apply - the todays date value cell occurs every 20 cells.
