Full-sized drag & drop JavaScript event calendar with resource view:
- Lightweight (28kb br compressed)
- Zero-dependency (pre-built bundle)
- Used on over 60,000 websites with Bookly
Inspired by FullCalendar, implements similar options.
The first step is to install the Event Calendar core
package:
npm install --save-dev @event-calendar/core
Then install any additional plugins you plan to use:
npm install --save-dev @event-calendar/time-grid
You must use at least one plugin that provides a view. The following plugins are currently available:
@event-calendar/day-grid
@event-calendar/list
@event-calendar/resource-time-grid
@event-calendar/time-grid
@event-calendar/interaction
(doesn't provide a view)
Then, in your Svelte component, use the calendar something like this:
<script>
import Calendar from '@event-calendar/core';
import TimeGrid from '@event-calendar/time-grid';
let plugins = [TimeGrid];
let options = {
view: 'timeGridWeek',
events: [
// your list of events
]
};
</script>
<Calendar {plugins} {options} />
Or in ES6 module:
import Calendar from '@event-calendar/core';
import TimeGrid from '@event-calendar/time-grid';
let ec = new Calendar({
target: document.getElementById('ec'),
props: {
plugins: [TimeGrid],
options: {
view: 'timeGridWeek',
events: [
// your list of events
]
}
}
});
The CSS is located at @event-calendar/core/index.css
. If your build tool supports CSS processing, you can import it like this:
import '@event-calendar/core/index.css';
Include the following lines of code in the <head>
section of your page:
<link rel="stylesheet" href="https://cdn.jsdelivr.net/npm/@event-calendar/[email protected]/event-calendar.min.css">
<script src="https://cdn.jsdelivr.net/npm/@event-calendar/[email protected]/event-calendar.min.js"></script>
Note
Please note that the file paths contain an indication of a specific version of the library. You can remove this indication, then the latest version will be loaded:
<link rel="stylesheet" href="https://cdn.jsdelivr.net/npm/@event-calendar/build/event-calendar.min.css"> <script src="https://cdn.jsdelivr.net/npm/@event-calendar/build/event-calendar.min.js"></script>But it is recommended to always specify the version and explicitly update it if necessary, in order to avoid unpredictable problems when a new version of the library is released.
Then initialize the calendar with something like this:
let ec = new EventCalendar(document.getElementById('ec'), {
view: 'timeGridWeek',
events: [
// your list of events
]
});
You can modify the calendar options after initialization using the setOption method.
ec.setOption('slotDuration', '01:00');
In Svelte, you can simply update the original options
object.
<script>
import Calendar from '@event-calendar/core';
import TimeGrid from '@event-calendar/time-grid';
let plugins = [TimeGrid];
let options = {
view: 'timeGridWeek'
};
function updateOptions() {
options.slotDuration = '01:00';
}
</script>
<button on:click={updateOptions}>Change slot duration</button>
<Calendar {plugins} {options} />

You can specify options that apply only to specific views. To do so provide separate options objects within the views
option, keyed by the name of the view.
Methods allow you to manipulate the Event Calendar after initialization. They are accessible from the calendar instance.
In Svelte, methods are available from a component instance:
<script>
import Calendar from '@event-calendar/core';
import TimeGrid from '@event-calendar/time-grid';
let ec;
let plugins = [TimeGrid];
let options = {
view: 'timeGridWeek',
eventSources: [{events: function() {
console.log('fetching...');
return [];
}}]
};
function invokeMethod() {
ec.refetchEvents();
}
</script>
<button on:click={invokeMethod}>Refetch events</button>
<Calendar bind:this={ec} {plugins} {options} />
- Parameters
name
string
The option name
- Return value
mixed
orundefined
This method allows you to get the current value of any calendar option.
// E.g. Get current date
let date = ec.getOption('date');
- Parameters
name
string
The option namevalue
mixed
The new option value
- Return value
EventCalendar
The calendar instance for chaining
This method allows you to set new value to any calendar option.
// E.g. Change the current date
ec.setOption('date', new Date());
- Return value
Event[]
Array of Event objects
Returns an array of events that the calendar has in memory.
- Parameters
id
string|integer
The ID of the event
- Return value Event object or
null
Returns a single event with the matching id
.
- Parameters
id
string|integer
The ID of the event
- Return value
EventCalendar
The calendar instance for chaining
Removes a single event with the matching id
.
- Parameters
event
object
A plain object that will be parsed into an Event object
- Return value Event object or
null
Adds a new event to the calendar.
- Parameters
event
object
A plain object or Event object
- Return value
EventCalendar
The calendar instance for chaining
Updates a single event with the matching event
.id
.
- Return value
EventCalendar
The calendar instance for chaining
Refetches events from all sources.
- Return value
object
ornull
Returns an info
object with data as if the dateClick event had fired for that point.
info
object contains the following properties:
|
JavaScript Date object for the date and time |
|
|
|
HTML element that represents the whole-day that contains the point |
|
If the current view is a resource view, the Resource object that owns this date |
Using this method, you can, for example, find out on which day a click occurred inside a multi-day event. To do this, inside eventClick, pass the jsEvent.clientX
and jsEvent.clientY
coordinates to dateFromPoint
and get the desired date.
Note
In the
'listDay'
,'listWeek'
,'listMonth'
and'listYear'
views, the events are rendered outside the day container, so the method will returnnull
for the coordinates that are inside the events.
- Return value

Destroys the calendar, removing all DOM elements, event handlers, and internal data.
- Return value
View
Returns the View object for the current view.
- Return value
EventCalendar

This is a JavaScript object that the Event Calendar uses to store information about a calendar event.
Here are all properties that exist in Event object:
|
A unique string identifier of the event |
|
An array of resource IDs that the event is associated with |
|
|
|
JavaScript Date object holding the event’s start time |
|
JavaScript Date object holding the event’s end time |
|
The text appearing on the event |
|
The HTML version of the title |
|
|
|
|
|
|
|
The rendering type of the event. Can be In addition, in your callback functions, you may get the |
|
The eventBackgroundColor override for this specific event |
|
A plain object holding miscellaneous properties specified during parsing in the explicitly given |
When Event Calendar receives an array of plain event’s objects either from the events
option or as a result of an HTTP request to a URL of an event source, it parses the input objects into proper Event objects.
Here are all admissible fields for the event’s input object:

Here are all properties that exist in Duration object:
|
The number of years in duration |
|
The number of months in duration |
|
The number of days in duration |
|
The number of seconds in duration. If you want hours and minutes, you need to do division on this property |
|
Determines whether the duration represents a time period in weeks. This value is set during parsing the input data |
When Event Calendar receives a value for options like duration
, scrollTime
, slotDuration
and others, it parses it into a proper Duration object.
The admissible input value can be specified in one of three formats:
- an object with any of the following keys:
year
,years
,month
,months
,day
,days
,minute
,minutes
,second
,seconds
- a string in the format
hh:mm:ss
orhh:mm

specifies 5 hours - an integer specifying the total number of seconds
This is a JavaScript object that the Event Calendar uses to store information about a resource. Calendar events can be associated with resources and displayed separately using the resource view.
Here are all properties that exist in Resource object:
|
The unique string identifier for the resource |
|
The title of the resource |
|
The HTML version of the title |
|
Default background color for this resource's events |
When Event Calendar receives an array of plain resource’s objects for the resources
option, it parses the input objects into proper Resource objects.

A View object contains information about a calendar view, such as title and date range.
Here are all properties that exist in View object:
|
Name of the view |
|
Title text that is displayed at the top of the header toolbar |

JavaScript Date that is the start of the interval the view is trying to represent. For example, in month view, this will be the first day of the month. This value disregards hidden days |
|
JavaScript Date that is the end of the interval the view is trying to represent. Note: This value is exclusive. For example, in month view, this will be the day after the last day of the month. This value disregards hidden days |
|
JavaScript Date that is the first visible day. In month view, this value is often before the 1st day of the month, because most months do not begin on the first day-of-week |
|
JavaScript Date that is the last visible day. Note: This value is exclusive |
