Guide to the Calendar application.

Overview
========

IMPORTANT: Calendar is a prototype application. See
@{article:User Guide: Prototype Applications}.

Calendar allows you to schedule parties and invite other users to party with
you. Everyone loves to party. Use Calendar primarily for partying.


Reminders
=========

Calendar sends reminder email before events occur. You will receive a reminder
if:

  - you have marked yourself as **attending** the event;
  - the event has not been cancelled; and
  - the event was not imported from an external source.

Reminders are sent 15 minutes before events begin.


Availability
============

Across all applications, Phabricator shows a red dot next to usernames if the
user is currently attending an event. This provides a hint that they may be in
a meeting (or on vacation) and could take a while to get back to you about a
revision or task.

You can click through to a user's profile to see more details about their
availability.

Status Icons
============

On the month and day views, Calendar shows an icon next to each event to
indicate status. The icons are:

  - {icon user-plus, color=green} **Invited, Individual**: You're personally
    invited to the event.
  - {icon users, color=green} **Invited, Group**: A project you are a member
    of is invited to the event.
  - {icon check-circle, color=green} **Attending**: You're attending the event.
  - {icon times-circle, color=grey} **Declined**: You've declined the event.
  - {icon times, color=red} **Cancelled**: The event has been cancelled.

If you don't have any special relationship to the event and the event does not
have any special status, an event-specific icon is shown instead.

Importing Events
================

You can import events from email and from other calendar applications
(like Google Calendar and Calendar.app) into Calendar. For a detailed
guide, see @{article:Calendar User Guide: Importing Events}.


Exporting Events
================

You can export events from Calendar to other applications by downloading
events as `.ics` files or configuring a calendar subscription.

Calendar also attaches `.ics` files containing event information when it sends
email. Most calendar applications can import these files.

For a detailed guide to exporting events, see
@{article:Calendar User Guide: Exporting Events}.


Recurring Events
================

To create a recurring event (like a weekly meeting), first create an event
normally, then select {nav Make Recurring} from the action menu and configure
how often the event should repeat.

**Monthly Events on the 29th, 30th or 31st**: If you configure an event to
repeat monthly and schedule the first instance on the 29th, 30th, or 31st of
the month, it can not occur on the same day every month because some months
do not have enough days.

Instead, these events are internally scheduled to occur relative to the end
of the month. For example, if you schedule a monthly event on the 30th of a
31 day month, it will occur on the second-to-last day of each following month.

**Complex RRULEs**: Calendar supports complex RRULEs internally (like events
that occur every-other Thursday in prime-numbered months) but does not
currently have a UI for scheduling events with complex rules.

Future versions of Calendar may improve support for complex scheduling by using
the UI. In some cases, a partial workaround is to schedule the event in another
application (which has more complex scheduling controls available) and then
import it into Calendar.
