Bootstrap Calendar - examples & tutorial


Bootstrap 5 Calendar plugin

MDB calendar is a plugin that allows you to efficiently manage tasks. Thanks to this extension you will be able to easily create new events, manage current events, move existing events between other days, and store all data in an easily readable array.

Responsive Calendar plugin built with the latest Bootstrap 5. Various customization options like default view, event formats, customizable captions, and much more.

Note: Read the API tab to find all available options and advanced customization

Basic example

A few predefined events allowing you to see how the plugin looks like.

Event formats

Calendar events can be added with time in two different formats - 12h or 24h. Optionally, you can also use the moment static getter which returns the current date object. We recommend reading the moment library documentation before using this method.

Monday first

Set the data-mdb-monday-first attribute to true so that Monday is the first day of the week.

Default view

Set the data-mdb-default-view attribute to week or list to change the start view. By default, it is a month.

Twelve hour

By setting the data-mdb-twelve-hour attribute to true, you get a 12-hour schedule.

Customize captions

You can customize all captions very easily using data attributes. Detailed options are described in the API tab.

Default date

A starting day can be easily set using the data-mdb-default-date attribute.


The editable mode can be easily disabled using the data-mdb-readonly attribute.
