I know this is a wired question though...

Hi Experts,

 

Here is my question. I have this frame for time periods. 

 

                                                                                                   I also have records which have the start and end time. I want to know how many customers fall into which time period.  How should I link tables together?

                                                                                                          any idea would be appreciated.
