Adding a calendar to a to-do list can significantly enhance its functionality and usability. It transforms the to-do list from a simple task tracker into a more comprehensive time-management tool.A calendar view enables users to understand the context of their tasks within a larger timeline, making it easier to plan ahead and allocate time efficiently. This kind of visualization helps in goal-setting, tracking progress, and identifying free time slots for new activities, leading to better productivity and time management.
