Multiple calendar views 

Switch between different calendar views, including day, week, and month, to gain a comprehensive overview of your schedule or focus on specific time periods as needed.

By assigning different colors to various event types or members, users can quickly identify and differentiate between different categories of events or the creators of each event. For example, you can assign a distinct color to personal appointments, work-related tasks, or social events, allowing for a visual understanding of the types of events and their distribution. Additionally, you can include events on your calendar that you aren’t attending but want to be aware of, like a team meeting or a friend’s birthday party, by giving them a unique color. This level of customization enhances the usability of the online calendar.

Share functionality

Drawback of using existing calendars (E.g. Apple, Outlook, Google calendar) as your online calendar

It is essential for online calendar platforms to prioritize strong shared and collaborative capabilities. The best online calendars will provide both advanced event management capabilities and also seamless sharing functionality, ensuring that all members have easy access to a dedicated calendar. In addition, Shared visibility, real-time synchronization, and edit accessibility are essential features that enable collaboration and keep everyone on the same page. By offering these vital features, the online calendar allows you to maintain a unified approach toward scheduling.

When relying on traditional calendar apps as your online calendar, you may encounter certain drawbacks related to collaboration. Sharing the calendar with others can be a time-consuming and error-prone process, as it often requires manual input of email addresses for each event. Furthermore, the synchronization and real-time updates in these apps may not always be reliable leading to missed updates among users.

Another limitation lies in the user interface of existing calendar apps. Rather than providing individual pages for each calendar, where you can clearly view, manage, and customize the proper calendar,  these apps often offer only a centralized page where you can view calendars altogether. This approach makes the calendar less organized and difficult to manage efficiently, particularly when dealing with various calendars. Moreover, these apps were primarily designed for individual use, lacking specific features and functionalities that cater to the collaborative needs of today’s society.

Lastly, These widely used online calendar apps, such as Apple, Outlook, and Google Calendar, lack advanced customization and indication features. Users are unable to design their calendar with a photo or banner that boosts the appearance and allows members to spot it swiftly. Additionally, there is no option to assign colors to individual members’ events, and an absence of visual cues like images, icons, or letters to indicate the creator of each event.
