In Japan, there is a service called ADVENTAR that hosts the "Advent Calendar" by blog. It is also hosted by a technical blog service called Qiita.
Since the spread of Mastodon in Japan in 2017, a calendar using these services has been created for each user of Mastodon, distributed SNS, and servers every year, and many articles have been contributed.

This year, I created a calendar called Fediverse Advent Calendar 2020. Currently, there are 57 articles entered using the three calendars. I expect there will be a few more in the future.

All the scheduled articles are in Japanese, but please read them in machine translation. Your entries are also welcome. Of course, you can write in English or your own language.
