Should I get a dated or undated weekly planner?

Across r/planners discussions, dated planners win for people with hard deadlines, recurring appointments, or ADHD-driven need for external structure, because pre-printed dates create accountability. Undated planners are favored by users who plan inconsistently, start mid-year, or want to skip weeks without guilt. If you're not sure you'll use it daily, reviewers across the planner communities lean undated to avoid wasted pages.
