Event

Represents an event in the calendar. In the user interface, event and task records are collectively referred to as activities.

An EventRelation object can’t be related to a child event, and child events don’t include the invitee related list.
query(), delete(), and update() aren’t allowed with events related to more than one contact in API versions 25.0 and earlier.

Fields

Field	Details
AccountId	Type reference Properties Filter, Group, Nillable, Sort Description Represents the ID of the related Account. The AccountId is determined as follows. If the value of WhatId is any of the following objects, then Salesforce uses that object’s AccountId. Account Opportunity Contract Custom object that is a child of Account If the value of the WhatId field is any other object, and the value of the WhoId field is a Contact object, then Salesforce uses that contact’s AccountId. (If your organization uses Shared Activities, Salesforce uses the AccountId of the primary contact.) Otherwise, Salesforce sets the value of the AccountId field to `null`. For information on IDs, see ID Field Type.
ActivityDate	Type date Properties Create, Filter, Group, Nillable, Sort, Update Description Contains the event’s due date if the IsAllDayEvent flag is set to `true`. This field is a date field with a timestamp that is always set to midnight in the Coordinated Universal Time (UTC) time zone. Don’t attempt to alter the timestamp to account for time zone differences. Label is Due Date Only. This field is required in versions 12.0 and earlier if the IsAllDayEvent flag is set to `true`. The value for this field and StartDateTime must match, or one of them must be `null`.
ActivityDateTime	Type dateTime Properties Create, Filter, Nillable, Sort, Update Description Contains the event’s due date if the IsAllDayEvent flag is set to `false`. This field is a regular Date/Time field with a relevant time portion. The time portion is always transferred in the Coordinated Universal Time (UTC) time zone. Translate the time portion to or from a local time zone for the user or the application, as appropriate. Label is Due Date Time. This field is required in versions 12.0 and earlier if the IsAllDayEvent flag is set to `false`. The value for this field and StartDateTime must match, or one of them must be `null`.
ClientGuid	Type string Properties Filter, Group, Nillable, Sort Description The client globally unique identifier identifies the external API client used to create the event. Label is Client GUID.

DurationInMinutes	Type int Properties Create, Filter, Group, Nillable, Sort, Update Description Contains the event length, in minutes. Note that even though this field represents a temporal value, it is an integer type—not a Date/Time type. This field is required in versions 12.0 and earlier if IsAllDayEvent is false. In versions 13.0 and later, this field is optional, depending on the following: If IsAllDayEvent is true, you can supply a value for either DurationInMinutes or EndDateTime. Supplying values in both fields is allowed if the values add up to the same amount of time. If both fields are `null`, the duration defaults to one day. If IsAllDayEvent is false, a value must be supplied for either DurationInMinutes or EndDateTime. Supplying values in both fields is allowed if the values add up to the same amount of time. If the multiday event feature is enabled, then API versions 13.0 and later support values greater than 1440 for the DurationInMinutes field. API versions 12.0 and earlier can’t access event objects whose DurationInMinutes is greater than 1440. For more information, see Multiday Events.
EndDateTime	Type dateTime Properties Create, Filter, Nillable, Sort, Update Description Available in versions 13.0 and later. This field is optional, depending on the following: If IsAllDayEvent is true, you can supply a value for either DurationInMinutes or EndDateTime.

However, users with the View All Data or Modify All Data permission can see private events in reports and searches, or when viewing other users’ calendars. Private events can’t be associated with opportunities, accounts, cases, campaigns, contracts, leads, or contacts. Label is Private.
IsRecurrence	Type boolean Properties Create, Defaulted on create, Filter, Group, Sort Description Indicates whether the event is scheduled to repeat itself (`true`) or only occurs once (`false`).

StartDateTime	Type dateTime Properties Create, Filter, Nillable, Sort, Update Description Indicates the start date and time of the event. Available in versions 13.0 and later. If the Event IsAllDayEvent flag is set to true (indicating that it is an all-day Event), then the event start date information is contained in the StartDateTime field. This field is a date field with a timestamp that is always set to midnight in the Coordinated Universal Time (UTC) time zone. The timestamp is not relevant, and you should not attempt to alter it to account for any time zone differences. If the Event IsAllDayEvent flag is set to false (indicating that it is not an all-day event), then the event start date information is contained in the StartDateTime field. The time portion is always transferred in the Coordinated Universal Time (UTC) time zone. You need to translate the time portion to or from a local time zone for the user or the application, as appropriate.

If Shared Activities is enabled, this field contains the ID of a related lead or primary contact, and if you add or remove the field, then you may encounter problems with triggers, workflow, and data validation rules.

Usage

Use Event to manage calendar appointments.

Querying and Filtering Events

Queries on events will be denied before they time out if they involve amounts of data that are deemed too large. In such cases, the exception code OPERATION_TOO_LARGE is returned. If you receive OPERATION_TOO_LARGE, refactor your query to return or scan a smaller amount of data.

When querying for events with a specific due date, you must filter on both the ActivityDateTime and ActivityDate fields. For example to find all events with a due date of February 14, 2003, you need two filters:

One filter with the ActivityDate field equal to the Coordinated Universal Time (UTC) time zone on February 14, 2003.
One filter with the ActivityDateTime field greater than or equal to midnight on February 14, 2003 in the user’s local time zone AND less than or equal to midnight on February 15, 2003 in the user’s local time zone.

Alternatively, in version 13.0 and later, you can find events with a specific due date by filtering on StartDateTime. For example, to find all events with a due date of February 14, 2003, filter with the StartDateTime greater than or equal to midnight on February 14, 2003 in the user's local time zone AND less than or equal to midnight on February 15, 2003 in the user's local time zone.

The EventId field of an EventRelation object always points to the master record. An invitee on a group event can query the EventRelation object to view the master record.

Multiday Events

Multiday events are available in version 13.0 and later. Also, in earlier versions SOQL queries do not return multiday events.
Multiday events are enabled through the user interface from Setup by clicking Customize | Activities | Activity Settings.
If the multiday event feature is enabled, then API versions 13.0 and later support values greater than 1440 for the DurationInMinutes field. API versions 12.0 and earlier can’t access event objects whose DurationInMinutes is greater than 1440.
Multiday events can’t exceed 14 days.

Recurring Events

Recurring events are available in version 7.0 and later.
After an event is created, it can’t be changed from recurring to nonrecurring or vice versa.
When you delete a recurring event series through the API, all past and future events in the series are removed. However, when you delete a recurring event series through the user interface, only future occurrences are removed.
When creating a recurring event series, the duration of the event must be 24 hours or less (either the DurationInMinutes or the difference between RecurrenceStartDateTime and EndDateTime must be greater than 24 hours). Once the recurring event series is created, you can extend the length of individual occurrences beyond 24 hours if Multiday events are enabled; see Multiday Events.
If IsRecurrence is true, then RecurrenceStartDateTime, RecurrenceEndDateOnly, RecurrenceType, and any properties associated with the given recurrence type (see the following table) must be populated.
When updating a recurring event series, it’s not possible to update the EventRelation for the event series object and the EventRelation for the series object occurrences at the same time.

The following table describes the usage of recurrence fields. Each recurrence type must have all of its properties set. All unused properties must be set to null.

RecurrenceType Value	Properties	Example Pattern
RecursDaily	RecurrenceInterval	Every second day
RecursEveryWeekday	RecurrenceDayOfWeekMask	Every weekday - can’t be Saturday or Sunday
RecursMonthly	RecurrenceDayOfMonth RecurrenceInterval	Every second month, on the third day of the month
RecursMonthlyNth	RecurrenceInterval RecurrenceInstance RecurrenceDayOfWeekMask	Every second month, on the last Friday of the month
RecursWeekly	RecurrenceInterval RecurrenceDayOfWeekMask	Every three weeks on Wednesday and Friday
RecursYearly	RecurrenceDayOfMonth RecurrenceMonthOfYear	Every March on the twenty-sixth day of the month
RecursYearlyNth	RecurrenceDayOfWeekMask RecurrenceInstanceRecurrenceMonthOfYear	The first Saturday in every October
