In Past X Days in Campaign Filters and Steps
Issue
You are setting times using natural language inputs, but are wondering: if I set a constraint of "in past 2 days", will that looks at the last 48 hours or will it look at the last two calendar days from Midnight-Midnight based on the timezone specified in my instance?
Solution
Using a constraint that is looking "in past 2 days" will look at the last 48 hours, if it was set as "in past 3 days" it would look at the last 72 hours, etc.
