How do I change the end date/time of an event automatically?

We are in lightning using actions to create an event.

A user is allowed to enter a start date in the past. When a user does this, the end date stays today and does not automatically change to the date of the start date. So if today is 6/26/2018 and the user enters a day in the past as the start date, they want the end date to automatically be that date int eh past as well after saving.

They are allowed to enter dates in the past so a validation rule is out. In a WFR I can not see how to use the end daste in the criteria. I tried process builder and it does not seem to be firing when using an action in Lightning. 

Is this possible in lightning or just yet another limitation?

You can use process builder to update End date based on the start date. Process builder should run here. 

There must be some issue with your process builder.
