Budget Spreadsheet help!

I have pretty much finished the spreadsheet...I dont know if this is even possible, but I would like to input the date of each paycheck and have my expenses calculate based on due dates. For example I get two pay checks and I want the bills due after paycheck 1 but before paycheck 2 to be calculated in my expenses for paycheck 1 and vice versa....

Is this possible?

ps my brain hurts
