Count Data, help with Dax

[Alopez11]

Hello, I need a hand with a Dax formula
I got the following data set:

Date          Time    T°   
1-1-2011   0:30     3

1-1-2011   01:00   3,5
1-1-2011   01:30   3
1-1-2011   02.00   3

Etc

I've made the following chart

With the Max and Min temperature of each day and 2 min and max lines at 10°C and 20°C

Now, what I need is to count all the days that the min temperature is over or equal to 10°C and lower or equal to 20°C to display in a labbel

Thanks you very much for the help

@Alopez11 Try:

Count = 
  COUNTROWS(
    FILTER(
      SUMMARIZE('Table',[Date],"__Min",MIN('Table'[T])),
      [__Min] >= 10 && [__Min] <= 20
    )
  )

Hello @Greg_Deckler 
thanks for your help, is now working
I have to make an upgrade to your formula as only use the Min value and not the Max so I made the following

Dias Efectivos de Polinizacion =

countrows(FILTER(SUMMARIZE('Base de Datos','Date'[Date],"__MIN",min('Base de Datos'[T°]),"__MAX",max('Base de Datos'[T°])),[__MIN]>=10&&[__MAX]<=20))
Thanks!
