I am currently trying to get ArcGIS 10.4 to symbolise point features by utilising a date field.
All my features have a 'last reviewed' date.
Ideally, I would like ArcGIS to symbolise my features by the following by using today's date on start-up
1. If the 'last reviewed' date is over 1 year ago
2. If the date is within 1 year
3. If the date field is blank
