If we want to restrict change location to 30 days in the past, how can we do that in redwood?

Summary:

We want to put restriction that any change location action can happen only 30 days in the past. How can we add this validation/restriction on the effective start date? We can probably use the validation rule, but if someone can guide the steps or conditions on how to add that, it will be huge help. Thank you
