Anime-Calendar is an anime iCal service, to sync your airing anime with your calendar, such as google calendar, outlook, iphone and many more.

If the anime is licensed, it will show the time when it is available to stream, otherwise it will show the japan airing time (Converted to your local time).

As of now the setup is a bit complicated. It is however planed to sync it with your public anime list profile in the future.

Before you can sync your animes to your calendar you need to let anime-calendar know which animes you watch / want to keep track of, for this you need to make a PUT request to the following REST Endpoint:

https://api.anime-calendar.com/v2/personal/anime-calendar/<secret-id>

For this you can use a service such as restninja.

In the url you need to replace <secret-id>, with a unique id, since every one can put to any id, it is recommended to use a random string, to avoid collisions. The id must only contain upper / lower case letters and number with a max length of 128.

In the body you need to put a JsonArray with the ids of the animes you watch. You can find a list of animes and there ids here.

After you send the put request you can add the following url to your calendar, where <secret-id> is the id you used in the put request.

https://api.anime-calendar.com/v2/personal/anime-calendar/<secret-id>/DE_DE

How you add an iCal feed to your calendar, depends on the calendar which you are using. Simple search for How to add iCal feed to <calendar> and there should be guid for it.
