6 min readMar 27


Calendars are extremely important in our hectic way of living. People use mobile or desktop calendars for appointing meetings, booking trips, or checking deadlines. Calendars and schedulers are an integral part of such applications as travel dashboards, admin panels, project management solutions, etc. We’ve gathered a selection of the most up-to-date and practical tools from the JS libraries and frameworks presently in use for this overview.

Before talking about the calendars, let’s mention the most frequent expectations of users and developers from similar solutions.

  • Detailed documentation.

Though a calendar might seem to be pretty easy to integrate, well-structured documentation is a must. Full documentation speaks volumes about the team of developers behind the product. To be confident of the result and to be more likely to find another option, you would choose a trustworthy team.

  • Easy customization.

Any project requirements may be updated, so it is good to have a flexible tool under the belt. A worthy scheduler should be easy to set and adapt to any modifications.

  • Compatibility issues.

Selecting a solution with capability restrictions would be a mistake with the diversity of browsers and devices accessible today. A calendar has to be available worldwide in order for your app or website to be universally responsive.

  • Budget restrictions.

Another crucial element is the cost. The most important aspect of the project scarcely includes a JS calendar. So, before selecting a choice, the entire development budget should be taken into account.

Best JS Calendars and Schedulers

Webix Scheduler

Webix Scheduler is a powerful tool to create reservation systems, timetables, work schedulers or other apps that require scheduling and appointment management functionality. Webix Scheduler main features are:

— Customizable views, such as day, week, month, year, and timeline, along with the ability to switch between them easily.
— Drag-and-drop functionality for different dates and times, making it easy to schedule and reschedule events.

— Customizing the styling of events, such as the background color, font size, and border.
— Time zone support, which can be useful for applications that need to display events across different time zones.
— Serialization of data to and from JSON or XML formats, making it easy to exchange data with server-side applications.

DHTMLX JS Scheduler

One of the biggest advantages of using DHTMLX Scheduler is its flexibility in terms of customization. The library provides developers with multiple API methods to easily modify and extend the interface according to their specific needs. This can include adjusting the layout, colors, fonts, and styles of different elements, as well as adding custom buttons, menus, and tooltips.

Another powerful feature of DHTMLX Scheduler is its support for various types of data sources, including JSON, XML, and databases. This makes it easy to integrate with other web technologies and frameworks, such as React, Vue.js, and Angular.

Kendo UI Scheduler

One of the key features of Kendo UI Scheduler is its ease of use. The user-friendly interface makes it easy to create, edit, and manage appointments and events. Another important feature of Kendo UI Scheduler is its flexibility. It can be easily integrated into any application, and it is compatible with a wide range of platforms and frameworks.

Kendo UI Scheduler also comes with a range of customizable features that allow developers to fine-tune the tool to match the look and feel of their application. This includes options for changing the color scheme, adding custom graphics and icons, and adjusting the layout of the calendar.

React Big Calendar

One of the significant advantages of React Big Calendar is that it comes with built-in support for various types of events, such as all-day events, recurring events, and multi-day events. This enables developers to display different types of events accurately and efficiently, thus providing a more comprehensive view of schedules to users. Moreover, the calendar component supports multiple views, including daily, weekly, and monthly views, making it easy for users to access their events and schedules as per their preferences.

Syncfusion React Calendar

The Syncfusion React Calendar is a highly efficient and user-friendly component that enables seamless integration into any web application.

With four unique themes to choose from, including day, week, work week, and month views, users can personalize their experience to suit their preferences. The calendar also supports multiple date selection, which is a useful feature for scheduling events or appointments. Moreover, users can easily adapt the calendar to their preferred language settings, making it a versatile tool for global audiences.

Angular Calendar

The Angular Calendar component, while offering a range of features such as drag and drop functionality, resizing capabilities, and the ability to navigate views, is not an ideal option for mobile development. Despite this limitation, developers have the option to choose from a variety of offered components to create a custom solution that meets all their specific needs. Additional features of the component include the ability to group events, scroll through the timeline, and more.


Bootstrap is an open-source toolkit of templates and components for building JS UIs. Creating a calendar with the help of Bootstrap implies a completely unique design. All the buttons need to be done separately. The calendar can be translated into any language. The events are added to the calendar with the help of AJAX.

The particular project needs will determine which approach is best. Open-source products are typically much simpler in functionality and do not imply full support. If you are looking for something more sophisticated, try a tool with a commercial license. In this case, you will feel safe with competent support.
