Excel VBA to average based on a time range - vba

I have a series of values (Column B) that have a timestamp (Column A) in hh:mm:ss: AM/PM format. What I am trying to do is average the values in Column B for every 10 minutes past in Column A. For example, I would need to average all the values in Column A from 12:40:00 PM - 12:50:00 PM in Column B. Ideally the code could scan through the entire dataset to produce these 10 minute averages.
Thanks in advance

You've tagged this as a vba question, but the result can be easily achieved with a formula.
If you are using Excel 2007 or later, use the AVERAGEIFS function
=AverageIfS(B:B,A:A,">="&<StartTime>,A:A,"<"&(<StartTime>+10/1440))
Replace <StartTime> with a reference to a cell containing the beginning of your 10min period.

Excel: Insert blank row if non consecutive date

We have a process at work that runs every 31 hours and would like to have a column in an Excel 2010 spreadsheet that reflects the time and dates the process is due to run each day over the coming year e.g.
start date (Cell:A1):
10/31/2016 1:00
11/1/2016 8:00
11/2/2016 15:00
11/3/2016 22:00
11/5/2016 5:00
11/6/2016 12:00
11/7/2016 19:00
11/9/2016 2:00
11/10/2016 9:00
11/11/2016 16:00
11/12/2016 23:00
11/14/2016 6:00
I am currently using the formula: A2 =A1 + (31/24) to populate the dates and times in the column which appears to work ok. I need to insert a blank row between days that are not consecutive (in order to highlight that fact, to make it easier for the operators to read and not instigate the process at the wrong time!) which is where the difficulty lies. I am assuming that I will need a separate VBA function to step through each cell and compare the day date (ignoring time value.) in the previous cell, if day date is greater than 1 (as in not the following day.) insert a blank row.
I am looking for a solution to the following scenario but am struggling to get my head round it and would appreciate any guidance/ help anyone is able to provide.
Many thanks
You do not need a VBA Function for that, it can be accomplished with the function
A3 = IF(A2="",A1+31/24, IF(INT(A2+31/24)=INT(A2)+1,A2+31/24,""))
*For that to work, you will have to populate cells A1 and A2 manually, though.
You can use the INT() function to get the date part of a DateTime field, so it becomes simple to check if adding 31 hours will leave a 1 day gap in the sequence by checking INT(A2+31/24) = INT(A2)+1.
So, to explain the function, the part
IF(INT(A2+31/24)=INT(A2)+1,A2+31/24,"")
will check if the days are consecutive, and if so, it will fill the DateTime. If not, it will leave it blank.
The outer IF checks if the cell above is blank. If it is, the function will use the one above that.

Excel how to set a given value to date ranges

I need to automatically set a value of 8.45 hours work for the winter schedule (01 October till 15 June) and 6 hours work for a summer schedule (16 June till 30 September) for a time sheet done in Microsoft Excel.
The equation I am trying is the following:
=IF(AND(DATE($G$1,6, DAY(15))>=(DATE($G$1-1, 10, DAY(1))));(DATE($G$1,6, DAY(15))<A8;8.45;"")
But this keeps on returning formula errors and this still omits the rate value for the summer schedule.
$G$1 is the year that is manually inputted for the yearly time sheet.
A8 is the current date.
Any guidance into this equation would be appreciate.
With best regards Fab
Edit
Thanks DirkReichel, Scott Craner, Alex Bell, Michael Uray for your great intervention.
I tried all the suggestions but some returned a =VALUE error and some did not omit the winter schedule as from the 1 October ->
This is the correct equation:
=IF(AND(DATE($G$1,9,30)>=A8,DATE($G$1,6,15)<=A8),6,8.45)
The equation checks the current date being A8 and checks if it falls withing the summer period (date range). If current date falls within the summer period the value is returned to 6, if the current date falls outside the summer period, it returns a value of 8.45.
Thanks to all that guided.
Depends on the regional settings, you may use comma "," instead of ";" as shown in the following example:
=IF(AND(NOW()>DATEVALUE("6/15/2016"), NOW()<DATEVALUE("9/1/2016")),6,8.45)
Hope this may help.
Try this:
=IF(AND(DATE($G$1,6,15)>=A8,DATE($G$1-1,10, 1)<=A8),8.45,6)
The following solution should work for you:
A1 is the date which gets checked, the formula is placed in B1.
On this way you can pull down a list of dates and formulas in your sheet.
=IF(AND(A1>DATE(YEAR(A1),6,15),A1<DATE(YEAR(A1),8,1)),6,8.45)
It checks if the data is in the range of YYYY-06-15 and YYYY-08-01 and sets then the output to 6, or if it is not in this range to 8.45
I did test it with e German Excel Version with the following formula and I translated it then manually in Notepad to the English formula version.
=WENN(UND(A1>DATUM(JAHR(A1);6;15);A1<DATUM(JAHR(A1);8;1));6;8,45)
I hope my formula translation will work for you in the English Excel version.

Excel Formula or VBA to convert year, month data to actual date

I have 2 columns (year and month). A sample data of year column A is 2015 at cell A2. A sample data of month column B is Jun at cell B2. I would like to convert these data to date format in column C to '2015-06-00` at cell C2. Is there a formula or Excel VBA to do this?
First off, 2015-06-00 is actually 31-May-2015. If you supply zero as the day-of-the-month, you get the last day of the previous month. Typically you would set it for the first day of the month. Use the DATE function for this with 1 as the day_num parameter or the DATEVALUE function if you are stringing together text-that-looks-like-a-date.
=datevalue(B2 & " 1, " & A2)
With a three letter month in B2, you will have to translate that to a numerical month if you opt for the DATE function.
=DATE(A2, LOOKUP(B2, {"Apr","Aug","Dec","Feb","Jan","Jul","Jun","Mar","May","Nov","Oct","Sep"}, {4,8,12,2,1,7,6,3,5,11,10,9}), 1)
in cell C "=FECHA(A2;B2;1)" (spanish excell)

Excel sub to fill out a table averaging data of another sheet

I am having issues to get data from several time stamps into usable data.
I am trying to fill out a table which the first of every column is a month (January --> December) and the first of every row is an hour of day (00 --> 23).
The table is to be filled out by averaging data from another sheet which consists of a timestamp (i.e. 2011-01-01 0:00) and an amount (i.e. XXXX.XX).
My current logic is this:
Get Cell Number (i.e. B2)
Get Hour and Month allocated to cell (i.e. 00 and January)
Loop through data and Average data of said month and hour from other sheet excluding weekend days
Can anyone help me figure out the coding for this?
Need sample data and also what you have tried so far. You can achive the same using Countifs and sumifs.
So a given cells will be sumifs/countifs to get the average time for the given hour and for the given month.
To know more you can use excel help for the given formulas.

When a start date and end date span more than one week, I need to split a row up in 2 or more new rows

I would like to begin by saying I'm quite new to sql.
That said, here is my question/problem:
I have a view that has two date columns, a variable column and a text column (for comments).
I need to be able to split up all rows where the two dates are not in the same week. And I need to be able to split the variable value as well, so that it gets evenly distributed, based on how many days were in each week. The comment must be copied as well, so to be shown in each row.
My dataset looks like this:
DateIn DateOut Amount Comment
2014-11-01 2014-11-08 600 Good
And what I want is this:
DateIn DateOut Amount Comment
2014-11-01 2014-11-07 525 Good
2014-11-08 2014-11-08 75 Good
And if the time period spreads over more weeks, I would need it to split up to equivalent number of rows.
I would be very greatful if somebody could take the time to tell me how to achive my goal, using an sql-query.
As this is my first post on the forum, I apologize for any format errors in my post.
First, you need a weeks table. I mean physical table or view, where exists one row for every week possible. (We have dates table here, +/- 30 years from now - allows easily create weeks view and similar).
Then you need link your data to weeks table with left join; join condition should check date ranges overlap with week date range (probably you have to have both week start and week end fields in your weeks table - makes comparisons easier).
Then you need to divide amounts between weeks. Because you know date range length, week length and overlapping date range length, this should be trivial :)
