Excel can organize data by half hour blocks...I just don't know how to do it.

I know I'm new here so I tried a search. Either it hasn't been crossed yet or I suck at searching. :(

I was give a report with 2 years worth of daily data. The Time/Date field is listed in the following format: 2009/06/09 14:25:47 I need to find a way to have excel organize these in half hour increments.

My end goal is a final report breaking down each day into half hour increments and showing how many inquiries came in during that half hour block.

Example (pic below) of desired final output:
on 2009/06/11, 6 inquires were handled, the end report (currently being counted in a separate spreadsheet) would show

1 for 3:00-3:30,
1 for 9:00-9:30,
1 for 11:00-11:30,
2 for 2:00-2:30 &
1 for 6:00-6:30.

like so. Note, the times written were provided by someone else. If everything has to be by 24 hr clock, I have no problem changing that.

Right now I'm counting these by hand but that's going to take forever. I have till the end of the week. :(

Have you tried using a pivot table? You can group the dates by Month, Day, and Hour increments...etc

Are you familiar with Pivot Tables?

You need to split the dates out into a column and split the 1/2 hour increments into a column

If your Date/Time values are in column H (starting at H15), put this in I15...
=INT(H15)
...and copy it down column I for each Date/Time in column H. This will give you the Date only with no Time values. You can format column I with any date format you like.

In J15 put this...
=MOD(INT(H15/(1/48))*(1/48),1)
...and copy it down column J for each Date/Time in column H. This will group each time into half hour intervals.

Now you could select your data and make a Pivot Table where the Dates are the columns, Time intervals are the Rows, and Count of half hour time intervals is the data.

First off, the skill of your internetz is amazing!

Next, I know you said to copy down the formulas for every date afterwards...I hope I'm just not understanding because that would mean I'd have to manually change the cell number for each formula that I copy. That's 2 years worth of cells.

Also, the date formula (to strip the time) copied the date but placed the timestamp as 00:00:00 and column J came out to a decimal. 0.020833333

I know the problem is between the chair and the keyboard so I may need a bit more hand holding. :)

Put the 1st formula in I15...
=INT(H15)
...and enter.

Click on cell I15 so there is a black outline around it
Notice the small black square in the lower right of the outline. That square is called the Autofill Handle. Grab it with the mouse and drag it down the column. This will automatically fill in the formulas down the column. The cell references will also automatically change e.g. H15 will change to H16, H17, H18 ...etc.

Put the formula in J15
Right-click on J15 and select Format Cells from the pop-up menu
On the "Number" tab, select a "Time" format you like and OK
Autofill the formulas down column J.

As far as making a Pivot table. Do a web search for "Excel Pivot Table Video" and watch a few. See can figure it out from there. If not, come back and ask a specific Pivot Table question.

It worked! And this is how I felt after seeing how easily it did work.
