Calendars are an important part of our lives. In today’s world, people mostly use the web or mobile calendars. They can be found everywhere, including various software: booking apps, travel software, project management, admin panels, etc.

Users may need calendars on websites for several reasons. The user may need to pick a date from the calendar to fill up a form or provide a date while delivering any information.

Undoubtedly, this component can be called critical for business applications. Just imagine how much your business can suffer due to a badly tuned and developed calendar. Thus, this component should be given special attention and meticulousness in development.

In this article, we will look at criteria for a good calendar in web applications. Also, we will show you the best libraries in different frameworks for building your own solutions based on them.

Qualities of a good calendar for web apps

We have picked the criteria for a good calendar from our previous article on date-pickers. Obviously, we can adapt these to calendar plugins. We divided our evaluation criteria into 4 blocks.

Documentation. It is vital for whatever you’re using to be well-documented in order to learn how to build or reconstruct it. The product with no or lacking documentation does not have a right to exist.

Customization. A great library should come with options that can be updated to add or remove certain functionality. This especially applies to open-source software.

Compatibility. Who wants to visit a site with a datepicker that only works in recent versions of Chrome and Webkit browsers? Many business apps still work in legacy browsers.

User Experience. Ask yourself whether the plugin will be convenient for the needs of your user? Does it fit your product style? The looks and quality of the docs are not that important compared to how the library will actually deal with your task.

Top calendar libraries

We have included various calendar libraries based on React, Angular, Vue, Bootstrap or jQuery. Some of them are more developed, some are easier to customize. Hope this catalog will help you in your work.
