# Calendaring introduction Anyone can read calendars shared publicly at Example orga. Your personal [[account]] grants read-only access to closed-group shared calendars. Custom group accounts provide write access to (closed-group or public) shared calendars. ## Special strings NB! This documentation uses special strings which you may want to adapt for your local setup: organisation: Example orga eventhost: event.example.org ## Clients Recommended calendaring client depends on the operating system you use: * Mac, iPhone and iPad: Apple Calendar * Windows and Linux: [Mozilla Thunderbird](https://www.thunderbird.net/) * Android: [DAVdroid](https://f-droid.org/app/at.bitfire.davdroid) and [ICSdroid](https://f-droid.org/app/at.bitfire.icsdroid) ## Read-only access When you only need to read a calendar, the best (most efficient) is to subscribe to an **iCal** calender: 1. Copy address of relevant calendar from web page . 2. Open calendaring client, and add new account profile of type "ical". 3. Paste the calendar address as server address. Closed-group calendars also require username and password, and require a secure connection (TLS or SSL, or "https://" address). ## Read-write access To both read a calendar and help maintain its content, you need to setup a **CalDAV** profile: 1. Open calendaring client, and add new account profile of type "CalDAV". 2. Server address: **event.example.org** 3. Username and password: Either personal or calendar-group account credentials. If above fails, or if you want to specifically pick a single calender, use this alternative approach: 1. Copy address of relevant calendar from web page **https://event.example.org/** (replace USERNAME with either personal or calendar-group account name) 2. Open calendaring client, and add new account profile of type "CalDAV". 3. Paste the calendar address as server address.
