Story of Johnny, Hard working atom splitter:
Meet Johnny, who lives by the intersection of lane 2345, and BAG street. Johnny (or little Jon as friends call him) is a hard working family guy. He works at local nuclear power plant in a neighborhood named Sheet3. Due to a recent re-organization at work place, Jon found himself reporting to an almost crazy boss named “Bill Lumbergh”.
Now, Lumbergh is not your everyday crazy boss, he is so much more than that. So, one day Lumbergh walks over to Jon’s desk and tells him, “Look Jon, we are having issues in the particle accelerator in the basement. It doesn’t seem to split atoms alright. So I need you to go there and split atoms manually. We got 12,789,000 atoms to be split before next weekend. So I am gonna go ahead and ask you to work on it. Ummkay?”
Just when Johnny thought of uttering a curse, Lumbergh came back and reminded, “Oh Johnny, remember to log how much time you are spending splitting atoms. I need you to tell me how many hours you worked for every million atoms. Make sure you follow the latest Timesheet report formats, or else…,”
Johnny muttered a couple of real ugly cuss words that are not blog worthy and went about his business of splitting atoms. He managed split only 11 million of them before the deadline given by Lumbergh. Those darned atoms!
Also, Johnny logged the time he spent for every million atoms using, well, excel. Like this:

Your homework:
Johnny needs your help to figure out how many hours he worked in total (as well as for each million). He is already tired hunting a missing electron in the basement alleys. So don’t tell him to count manually. He wants to have an excel formula that tells him how many hours he worked given a start and end date in cells A1 and A2 respectively. Remember,
- Johnny never works after 6pm or before 9am
- Johnny never works on weekends.
- Lets say Johnny doesnt take any lunch breaks (he has developed a taste for those higgs bosons sandwich with positron milk shake).
So I am gonna go ahead and ask you to complete this homework before the weekend. When you got the correct formula, come back here and post it in comments. Ummkay?

I can't open this pdf. I get the error message:
You do not have the required license to open this file.
Please request a license from the creator of the file, and add it using the license manager and they try opening it again.
What gives??
I downloaded the file again and it worked this time. Strange. (First file was 116 KB, second was 1644 KB... ???)

Hi Chandoo,
thanks for sharing your Excel 2007 learning experience with us; unfortunately the link to the pdf of the free Excel 2007 learning guide seems broken: my Acrobate Readers flags: "Unkown file type or corrupte data".
Have a nice day
Michael
well done this is great
Can somebody just provide a link the classic TAB exportedUI files for MS Office 2003 for us to use in office 2007/2010?. searching online, everybody just wnats to make a buck online with silly Classic Tab installers which do nothing more than inport exportedUI files for you.
Don't give me a ribbon how to guide, just give me free exportedUI files. I should not have to pay anyone for this, it is free XML, MS should have included this to begin with.
thanks
