Is there a way to get a calculated field to auto-refresh?

For example, I have an expiration date field with dates filled in. I have another field that I will use to show the number of days left till the expiration date. When I update the expiration date to a new date, is there a way to get the calculated fields to auto-refresh with out having to rerun the Field Calculation - GeoProcessing Tool python script?

Below I've provided a screen shot of my attribute table.

    im not sure about ArcGIS Pro but if you use ArcDesktop you can use "Attribute Assistant" to create an expression that will automatically calculate a field based on other fields. – ed.hank Jul 6 '18 at 18:26

    It is an add-on for ArcGIS Desktop. Download it here - solutions.arcgis.com/shared/help/attribute-assistant and then read the help file. It is quite useful for populating a field based on a custom expression or populating a field based on a spatial intersect. I use it quite a bit myself. – ed.hank Jul 6 '18 at 18:52

    Well attribute assistant is actually free, but you are correct i dont think it will work with ArcPRO. – ed.hank Jul 6 '18 at 20:49

    Look into "Attribute Rules" for ArcGIS Pro – Midavalo Jul 7 '18 at 2:38

    Attribute Rules - this is the ArcGIS Pro release of the Attribute Assistant. I don't think it's fully implemented all of the AA yet, but I think what you want may be included. – Midavalo Jul 7 '18 at 2:48
