Pull each instance of a Set Criteria/Value in a coulmn

Hello all,
I am currently working on a form that will automatically pull in only dates that fit a certain criteria. On the first page, as soon as it is opened, the current month and year fill in, this then sets the calendar on a separate sheet and assigns it the crew that will be working. I have set logic to place "True" to the right of ONLY the last day of a crews rotation and "False" to the right of all other days. On the first sheet I would like to recall every instance of "True" so that I have only the dates that are associated to the last week of that crews rotation.
the cells I am pulling the data TO are B6:B17
The date I want returned is =Sheet2!C3:C33
the instance I am looking for "True" is =Sheet2!E3:E33
what is the best way to do this? I can get the first instance using =INDEX(Sheet2!C3:C33,MATCH("True",Sheet2!E3:E33,0)) but am unsure as how to pull only the next instance of "True". etc. etc. ANY HELP?

Tony Valko! Thank you very much, this is going to help me tons! I'm given tons of documents to work on in just one day and this one I feel is actually important. Once I had endless time to slowly learn as I go but things seem more rushed these days, so you are a life saver. Thank you again! It works beautifully.
