How to find out the last date

I am filtering a certain date and I need to know the last date in that data list
How can I able to find out by using expression?

Aggregations are not available in expressions. Use the “Keep min/max” action.

The idiomatic approach in EasyMorph is to make actions do all the calculation heavy-lifting while keeping expressions light and simple.
