24HR Date Selection

Hi I am extremely new and green to PowerBI.   What I am doing now is building a downtime chart from a manufacturing environment.   What I would like to do though is gather data from 6am until 6am the next day.  IE the data needs to be from 4/12/19 at 6am until 4/13/19 6am and then ignore all data after the 6am time frame on the 13th.  Can someone explain on/where I would do this?

Thank You
