PI Data link Calculated Max Value Ignore Dates

Hi

I am using PI Datalink with “Calculated Data in max mode” and have it set up as follows   

Data Item = ‘Tag name’

Start Time = today

End time = -1year

Mode = Max

 

The code is working correctly by displaying the Max value for that tag

I need the program to ignore several dates but cannot find the correct expression for this.

 

I was using:

‘Tag name’ <> ‘1/05/2019’

 

Is there a way to express this?

 

Help would be much appreciated
