If points have a start date and end date in the attribute table, is it possible to symbolize them as active or inactive in AGOL based on the current date?
Yes, you can using Arcade.
In this map I am labeling by Start Date.
Add an Arcade Expression
A few ways of doing this, I took an "IF Else" approach.
var starttime = $feature.startdate;
var endtime = $feature.enddate
var currenttime = Now()
var status = ""
if (starttime > currenttime){
status = "Befor Start Date"
}
else if(currenttime < endtime){
status = "Active"
}
Else{
status = "Past End Date"
}
return status
Click OK and Done
Symbolized by status variable.
