Displaying time-relevant information in an ArcGIS Online web map

Hello everyone,

I have a specific thing I want to accomplish with a map I'm setting up: I have a point shapefile of several locations that each have "expiration dates" associated with them. I want to be able to create an application that allows a viewer to see the points symbolized by how close they are to the relevant date.

For example, if Point A expires in June, and Point B expires in September, I want to be able to show Point A as being 2 months away from its date (probably symbolized by a red color) and Point B as being 5 months away from its date (probably symbolized by a green color).

I sort of achieved this by doing a field calculation in ArcGIS, uploading the shapefile, and symbolizing it based on the calculated field, but this would require that I re-calculate the field and re-upload the shapefile every month to keep the information up-to-date. I want to know if there is a way to make this information dynamic, so that it doesn't have to be manually re-calculated and uploaded.
