Which view must include 2 date columns in order to be displayed?

The Gantt view requires two date columns to be displayed because it is designed to represent project timelines visually. The first date column typically denotes the start date of a task or project, while the second date column indicates the end date. This dual-date structure allows the Gantt chart to accurately depict the duration of tasks, making it a powerful tool for project management.

In this view, having both a start and an end date is essential for creating the bars that represent tasks on the timeline. The visual layout of the Gantt chart helps users quickly understand task schedules, overlaps, and dependencies within a project.

Other views, such as the Card view, Grid view, and Calendar view, serve different purposes or may not necessitate the presence of two distinct date columns. For instance, the Calendar view does incorporate date information but organizes items based on single date events rather than a duration defined by start and end dates.
