Date Range Verifier is Excluding Data Within its Supposed Range

Hi! good day!

I am currently using the formula below to determine if a record/records is within last weeks Sunday to Saturday. Sunday being start of the week and Saturday being end of the week.

AND(

       IS_AFTER(

           {Time in},

           DATEADD(

               DATEADD(

                   TODAY(),

                   -WEEKDAY(TODAY(), "Sunday") - 7,

                   "days"

               ),

               0,

               "days"

           )

       ),

       IS_BEFORE(

           {Time in},

           DATEADD(

               DATEADD(

                   TODAY(),

                   -WEEKDAY(TODAY(), "Sunday") + 0,

                   "days"

               ),

               0,

               "days"

           )

       )

   )

If today is the 20th of June then my Current formula will tag my June 8 , 8AM record as false. 

If I adjust the time to 8:30AM, formula will tag it as true,

would like the formula to include the entire day of sunday up to the entire day of saturday.

Appreciate the help!
