FAQ

I'm not sure which calendar to join.

Basically, anyone can join a publicly listed calendar.

However, only certain users can join the following calendars.

・Calendars linked to an Organization: Only members of that Organization can join.

・Calendars in the "Solo Advent Calendar" category: Only the calendar creator can join.

For how to identify calendars with limited participation, please see the help page.

Look for a calendar on a theme you can write about, such as a technology you use every day or a field you are interested in.

If you are unsure which calendar to join, try a Qiita official calendar is also a good option.
