A user, aDaxxas, installed the Discourse calendar plugin but couldn’t find documentation on how to use it. After asking for help, jomaxro provided a simple guide:
To use the calendar, include the [calendar] and [/calendar] BBCode in separate lines in the topic. Then, in subsequent replies, use the “Insert Date” function from the composer options menu to insert a single date or date range. For example:
[date=2018-12-20 timezone="America/Boise"] → [date=2018-12-21 timezone="America/Boise"]
Once the reply is submitted, the date range will be added to the calendar in the OP, and the post will be automatically deleted once the event is over. The plugin topic has since been updated with more detailed usage instructions, as mentioned by jomaxro.
Hello,
I’ve installed the calendar plugin But I can’t find any wiki or else to know how to use it 
I didn’t find anything on the readme of the github, neither on the thread, I’m probably missing something there, but I can’t find anything 
The only thing I’ve seen is to use [calendar] [/calendar], and I did use it, but I don’t know how to write in the calendar the events
Please help me :c
We should improve the docs here some @jomaxro
No doc then ?
Can I have at least have a simple help then on how to use it please ?
Hi @aDaxxas, your request came in over the weekend, improving the documentation is on my list for early this week.
In short, you need to include the calendar BBCode in seperate lines in the topic:
[calendar]
[/calendar]
Then, in subsequent replies use the Insert Date function from the composer options menu to insert a single date or date range. For example,
[date=2018-12-20 timezone="America/Boise"] → [date=2018-12-21 timezone="America/Boise"]
Once the reply is submitted, the date range should be added to the calendar in the OP. Once the event is over the post containing the dates will be automatically deleted.
Thanks you!
It was simpler than I thought ^^
The plugin topic has been updated with more detailed usage instructions.
