Using this package, you can generate links to add events to calendar systems. Here's a quick example:

```php
use Spatie\CalendarLinks\Link;

Link::create(
    'Birthday',
    DateTime::createFromFormat('Y-m-d H:i', '2018-02-01 09:00'),
    DateTime::createFromFormat('Y-m-d H:i', '2018-02-01 18:00')
)->google();
```

This will output: `https://calendar.google.com/calendar/render?action=TEMPLATE&text=Birthday&dates=20180201T090000/20180201T180000&sprop=&sprop=name:`

If you follow that link (and are authenticated with Google), you’ll see a screen to add the event to your calendar.

The package can also generate ics files that you can open in several email and calendar programs, including Microsoft Outlook, Google Calendar, and Apple Calendar.

// Generate a link to create an event on Google calendar
echo $link->google();

// Generate a link to create an event on Yahoo calendar
echo $link->yahoo();

// Generate a link to create an event on outlook.live.com calendar
echo $link->webOutlook();

// Generate a link to create an event on outlook.office.com calendar
echo $link->webOffice();

// Generate a data URI for an ics file (for iCal & Outlook)
echo $link->ics();
echo $link->ics(['UID' => 'custom-id']); // Custom UID (to update existing events)
echo $link->ics(['URL' => 'https://my-page.com']); // Custom URL
echo $link->ics(['REMINDER' => []]); // Add the default reminder (for iCal & Outlook)
echo $link->ics(['REMINDER' => ['DESCRIPTION' => 'Remind me', 'TIME' => new \DateTime('tomorrow 12:30 UTC')]]); // Add a custom reminder
echo $link->ics([], ['format' => 'file']); // use file output; e.g. to attach ics as a file to an email.

// Generate a data URI using arbitrary generator:
echo $link->formatWith(new \Your\Generator());
```

## Package principles

1. it should produce a small output (to keep page-size small)
2. it should be fast (no any external heavy dependencies)
3. all `Link` class features should be supported by at least 2 generators (different services have different features)
