Time duration between multiple events with start and stop

Hi zinminthant 

You'd have to split the Events column to have the type of the event (Start, Stop...)  and the name of the entity the event happens on (A, B...) in separate columns. Best to do this in Power query. Then you can create a column like this:

Duration (hr) =
VAR previousStart_ =
    CALCULATE (
        MAX ( Table1[DateTime] ),
        ALLEXCEPT ( Table1, Table1[Entity] ),
        Table1[Event Type] = "Start",
        Table1[DateTime] < EARLIER ( Table1[DateTime] )
    )
RETURN
    IF ( Table1[Event Type] = "Stop", ( Table1[DateTime] - previousStart_ ) * 24 )
