# Sum Every Nth Cell & Calculate Difference Between 2 Different Time Interval List

Jan 24, 2008

I have two sets of data, one is recorded every 5 minutes and the other is every 15 minutes. I am trying to add every 3 cells in the 5 minute column so I can compare it side by side with the 15 minute column. I have tried one of the responses in this forum with placing 0s in 2 cells and then the formula in the third however this does not allow me to compare the 2 sets side by side.

## To Calculate The Difference Between The Start Time And End Time

May 3, 2008

This may be a bit vague but here goes.

I have to calculate the difference between the start time and end time of a job. The only catch is, how can I avoid calculating "out of hours" time. So, if a job goes from 9am to 9am the next day, I want it to avoid calculating between the hours of 23:30 and 03:30.

Another example is if a job goes from 02:00 to 04:00, I want it to avoid the tim between 02:00 and 03:00.

If there is a difference in days, so the job goes overnight, how do I take that into consideration also.

## Calculate Time Difference In Decimal Time

Aug 16, 2008

I've got a time difference from 8:00AM - 12:30PM as 4.30 I'm trying to get the minutes, .30, converted into a 6 minute increment, .5. Is it possible to do this and if so how would it be done? Below is a chart of how the time is converted from 6 minutes increments into decimal form.

6 = 0.1 36 = 0.6
12 = 0.2 42 = 0.7
18 = 0.3 48 = 0.8
24 = 0.4 54 = 0.9
30 = 0.5 60 = 1.0

## Calculate Time Difference In Various Multiples

Oct 16, 2007

I am setting up a time and attendance system.

What I want to do is calculate the overtime that someone has worked but in multiples of 15 minutes.

Example, if someone worked 20 minutes over they would be paid for 15 minutes overtime.
If someone worked 31 minutes over they would be paid 30 minutes overtime.

The possible overtime someone could work in one day is 6 hours.

I want it to return the overtime in decimal numbers (e.g 0.25 for 15 minutes overtime).

I have attached a sample spreadsheet.

I would prefer this to be done in VBA if possible?

## Calculate Time Difference That Spans Into Next Day

May 27, 2008

I'm trying to do some calculations involving times. I'm using the format [=A2+(A1>A2)-A1] in order to calculate times from one day to the next which avoids negative numbers. This is working well. My problem is now that I'm trying to develop my spreadsheet and am trying to embed this inside an IF statement as the [value_If_True]and I get an error because it doesnt like the leading equals sign inside the IF statement.

## Time Arithmetic - Calculate Hour Difference

Apr 10, 2014

Time arithmetic, I have two cells representing a time range.

The first one (say: X1) is formatted using the custom format [h]:mm and contains a certain number of hours and minutes. It gets its value by summing up other cells in the same format. A typical entry could be 98:35 to represent a duration 98 hours and 35 minutes.

The second cell (say: X2) is formatted as a number with 4 decimal places after the comma, and similarily gets its value by summing up other cells in the same format. It also represents a time duration as a number of hours. A typical entry could be 202.7500 to represent a duration of 202 hours and 45 minutes (because 0.75 of an hour is 45 minutes).

I would like to calculate the hour difference between these cells, and display it as hours and minutes. In the example given, the result should be negative, i.e. -104:10.

My first approach was to use the formula X1-X2 and format the result as [h]:mm, but this gives me a #VALUE! error.

## Formula To Calculate The Difference Of Time Between Cells

Feb 17, 2008

I'm working in excel2007:

I want to write a generic formula to calculate the difference of time between cells, the first being a real data point, such as

6/22/2007 8:53

minus a generic constant term using the same date and a given time, 8:30.

So, what I need is something like this:

6/22/2007 8:53 � (same mm/dd/yy @ 8:30)
6/22/2007 12:29 � (same mm/dd/yy @ 8:30)
6/25/2007 11:19 � (same mm/dd/yy @ 8:30)

## Calculate Time Difference Greater That 24 Hours

Aug 7, 2008

I have an excel spreadsheet where you enter the start time and end time for job function. Since some of the times cross midnight, I use the formula J3=IF(I3>H3,I3-H3,1+I3-H3) where I is the end time and H is the start time (format hh:mm). This part works fine, however when I sum column J and change my format to Time 37:38:00 (since it is over 24 hrs), it returns a large number of 2234:48:39 which should be closer to 223:00:00.

How would the formula looklike?

## 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

## How To Re-divide The Data At The Same Time Interval

Apr 18, 2009

I have 2 columns of data (value and time):

for example:

15 4/2/08 13:00
4 4/2/08 19:00
7 4/5/08 12:00
13 4/9/08 3:00

They are continuous data. so I want to divid the value into hourly data as follows.

15 4/2/08 13:00
? 4/2/08 14:00
? 4/2/08 15:00
. .
. .
? 4/9/08 2:00
13 4/9/09 3:00

## Determine Hours Per Time Interval?

Nov 2, 2013

Im trying to create a spreadshet to determin hrs per time interval

i.e

06:00 - 14:00
14:00 - 22:00
22:00 - 06:00

so a start time of 06:00 and finish time of 14:00 would show 8hrs in first interval and 0 in the other 2

and a start time of 10:00 and a finish time of 18:00 would show 4hrs in first interval and 6 in second and 0 in last

ive currently got start time in A1 , finish time in B1 and want hours for interval 1 in D1 , interval 2 in E1 and interval 3 in F1

## 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

## Time Difference Formula Where Both Times In 1 Cell

Aug 14, 2007

I need some IF formula I believe that will yield an answer between 1 - 5. I'm not swavey enough with these things to figure this one out... trust me I tried and it keeps getting more confusing for me.

If the time worked is between certain time criteria then it would equal 1 - 5 depending on the time.

Example: If I work between the hours of 5am and 1pm then I would be in the Open/Mid range and would need to equal 2. If I only worked a few hours and my hours fell only between the Mid range then it would equal 3.

Then based on that... It would automatically fill in on the deployment charts... My name would show up on the Open and Mid Deployments under the task chosen for me to do that day.

I've attached a small sample of what I am looking for to kind of help show what I need. The highlighted areas are the areas I'm not sure how to do.

## To 'round' A Time To The Next Nearest 15min Interval

Jun 23, 2006

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
want to show 5:45 PM in B1 etc etc

## 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 00:15:00
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

## 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.

## 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
