Help on formula for calculating days of work

Hi to you all,
I am designing a tracking sheet for number of days work. I want the excel tracking sheet I am using to only consider the actual working days but not even the extra weekend days.
For example; For 1-04-12 to 14-04-12, i want it to count 10 days and not actually 14 or 15.

Please I understand it is a weekend but i really need your help.

Thanks,
Renildrah

Thank you so much. It has worked; However, if i had like public holidays on some dates, how can i effect inconsideration of counting the date that is a public holiday? Take an example of 26th January of every year, 8th march, etc. How can i incorporate these days in my formula such that they are not considered as working days?

Thanks again
