A predefined date range shortcut used in Insights API queries (e.g., last_7d, this_month, etc.). It replaces specifying exact dates and is ignored if a custom time_range or time_ranges is given. Using date_preset simplifies queries by automatically setting common date spans (last week, last 30 days, etc.).
