An event calendar in Bubble uses the FullCalendar plugin to display events from your database on a monthly, weekly, or daily view. This tutorial covers installing and configuring the plugin, connecting it to your Event Data Type, handling click-to-add interactions, and syncing with external calendars.
Overview: Building an Event Calendar in Bubble
A visual calendar is essential for booking apps, event platforms, project management tools, and any app that works with dates. Bubble does not have a native calendar element, but the FullCalendar plugin provides a powerful, interactive calendar with month, week, and day views.
Prerequisites
- A Bubble app with an Event or Appointment Data Type
- The FullCalendar plugin installed (search in Bubble plugin marketplace)
- Basic understanding of Bubble elements and data binding
Step-by-step guide
Create the Event Data Type
Create the Event Data Type
Go to the Data tab and create a Data Type called Event with fields: title (text), start_date (date), end_date (date), description (text), color (text — hex color code), creator (User), all_day (yes/no). If you already have an event-like Data Type (Appointment, Meeting, etc.), you can adapt it.
Expected result: An Event Data Type ready to store calendar events.
Install and add the FullCalendar plugin element
Install and add the FullCalendar plugin element
Go to Plugins → Add plugins and search for FullCalendar. Install it. Back in the Design tab, click the + icon and search for the FullCalendar element (it appears under the plugin's name). Drag it onto your page and size it appropriately (at least 600x500px for a usable calendar).
Expected result: A FullCalendar element appears on your page ready for configuration.
Configure the calendar data source
Configure the calendar data source
Select the FullCalendar element. In the Property Editor, set the Event data source to Do a Search for Events. Map the required fields: Title field → title, Start date → start_date, End date → end_date, Color → color. Set the default view (month, week, or day). Enable navigation controls so users can switch between months and views.
Pro tip: Filter the data source with constraints relevant to the user — e.g., creator = Current User to show only their events, or a date range for performance.
Expected result: Events from your database appear on the calendar in their correct dates.
Add click interactions for creating and viewing events
Add click interactions for creating and viewing events
The FullCalendar plugin provides events for user interactions. Handle When a date is clicked to show a popup for creating a new event on that date — pre-fill the start_date with the clicked date. Handle When an event is clicked to show a popup or navigate to a detail page with the clicked event's data. Add forms inside popups for creating and editing events.
Expected result: Users can click dates to create events and click events to view or edit them.
Customize the calendar appearance
Customize the calendar appearance
Configure the calendar's visual settings in the Property Editor: set header colors, event colors (use the color field from your Data Type for per-event colors), font sizes, and which views are available (month, week, day, list). Set the first day of the week (Sunday or Monday). For additional customization, use the plugin's CSS override options or add custom CSS via an HTML element.
Expected result: The calendar matches your app's visual design with customized colors and views.

Why it's a problem: Not filtering events by date range
How to avoid: Add date range constraints to the data source: start_date >= first visible date AND end_date <= last visible date
Why it's a problem: Using the wrong date fields for start and end
How to avoid: Always set both start_date and end_date. For single-day events, set end_date = start_date + 1 day or use the all_day flag
Why it's a problem: Not handling timezone differences for event times
How to avoid: Store all dates in UTC (Bubble's default) and let the calendar plugin handle timezone conversion for display
Best practices
- Filter calendar data by the visible date range for performance
- Use color coding for different event types or categories
- Provide month, week, and day views for different use cases
- Pre-fill the date when users click to create a new event for better UX
- Store both start and end dates for every event
- Add a list view alongside the calendar for accessibility

Frequently asked questions
Which calendar plugin should I use?
FullCalendar is the most popular and feature-rich option. Air Calendar and Bubble's Date Picker are alternatives for simpler needs. Check plugin reviews and compatibility with your Bubble version.
Can I sync with Google Calendar?
Yes, via the API Connector and Google Calendar API. Push events to Google Calendar when created in Bubble, and pull Google Calendar events into your Bubble calendar.
Does the calendar work on mobile?
Yes. FullCalendar is responsive and works on mobile. The day and list views are most usable on small screens. Consider defaulting to day view on mobile breakpoints.
Can I add recurring events?
Create individual Event records for each occurrence of a recurring event. Use a backend workflow to generate events based on a recurrence pattern (weekly, monthly, etc.).
How many events can the calendar handle?
For smooth performance, keep visible events under 500 per view. Filter by date range and paginate if needed. For apps with thousands of events, optimize with backend aggregation.
Can RapidDev help with complex calendar features?
Yes. RapidDev has built calendar systems with drag-to-reschedule, resource allocation views, multi-timezone support, and Google Calendar sync in Bubble.
