compare calender dates

Hello, 

So my data sets contain the tablet usage of a few children. But few of the dates of usage are not proper and are showing the year 2020(because the children have changed the dates). How can I use a dynamic current date filter, as in the if the date in the data is beyond today it should not show the data. I want to do this so that I don't have to apply a filter manually to remove these data whenever we look at the data. Can anybody help me? 

Thank You, 

Kumar
