Custom Events sources allow you to display and manage events that are not based on Jira issues, sprints, versions, or worklogs.

Custom sources can be based on either default event types or custom-defined event types created by an administrator.

What you can do with Custom sources

Display custom events on the calendar
Use default or custom-defined event types
Create and manage events directly from the calendar
Configure displayed fields and event details
Customize event appearance and colors
Apply conditional colors based on event data
Control event overlap using concurrence rules
Receive email notifications for custom events
Define default event summaries

Available Event types

The following event types are available by default:

Business Trips
Meetings
Sick Days
Vacations and Leaves
Planning

Add Custom source

Open Calendar Configuration.
Navigate to Sources.
Select Custom and press Add Event Source.
Enter a source name.
Populate required fields
Save the configuration.

When a Custom Events source is added, the source name is automatically populated with the selected event type name.

Manage Event sources

Filter which issues appear

You can configure Project availability for custom events:

All Projects – Users can link events to issues from any Jira project.

Specific Project – Users can link events only to issues from the selected project.

No Project – Events are not linked to Jira projects or Jira issues.

This setting controls which Jira issues can be associated with events created from this source.

Configure event display

Under Issue Fields, select which Jira fields are displayed on events and in the event details dialog.

Option	Description

Option	Description
e	Display on the event block

You can add, remove, and reorder fields to customize how event information is presented throughout the calendar.

Advanced Features

The Advanced tab provides additional options for customizing the behavior and appearance of events created from a Custom Events source.

Conditional colors - Automatically apply different colors based on issue field values or conditions.
Email notifications - Receive notifications about Jira-based calendar events when email notifications are enabled globally by an administrator.
Default summary - Define the default title format for newly created issues.
Concurrence rules - Control how overlapping events are displayed and managed.

Conditional colors

Conditional colors allow you to automatically apply different colors to events based on configured conditions.

In addition, when it comes to custom events, you’ll be able to create the conditional colors that are based on custom fields such as Event Project, Event Description, Event User(s), Event Reporter, and Event Summary fields.

For detailed information about configuring conditional color rules, see Conditional Colors.

Default summary

The Default Summary option controls the default event title used when creating new events.

Available options:

None – no default summary is applied.
Source Name – use the source name as the event summary.
Issue Summary – use the linked issue summary as the event summary.
