They provide more than searching for dates, and they act much more like personal assistants which helps to keep you informed about each task.

Because iOS features are included in a unified calendar database, any changes or modifications made will be reflected in any calendar you’ve installed and vice versa. Everything is in unison and is organized regardless of how or where you utilize it. With Siri, you can make additions, and reviews, or even change your appointments quickly and effortlessly, using voice.
