A calendar is more than just a tool for checking dates. It helps people organize their daily activities, manage appointments, and plan their time more effectively. I think modern calendars should also include useful features like transport schedules, travel time calculators, and real-time updates to make daily planning easier.

For example, I developed a calculator on my website that helps people check updated Marmaray train timings in Istanbul. Instead of manually searching for departure times. https://marmarayduraklari.org.tr/marmaray-saatleri/

I believe integrating similar features into digital calendars would be a useful idea. Imagine selecting a date, choosing your departure station, and instantly seeing available train times alongside your scheduled activities. This could help daily commuters plan their journeys more accurately and avoid unnecessary waiting at stations.
