Update (11/28/2016): Dear writers, this year we are going to make an e-book from #FsAdvent posts and to raise money for a good cause (read more here). If you do not allow to use your post, please let me know.

F# Advent Calendar is an adorable idea, which has become a tradition:

• F# Advent Calendar in English: 2015, 2014
• F# Advent Calendar (in Japanese): 2015, 2014, 2013, 2012, 2011, 2010

Each year we’ve had an incredible Advent full of F# and Christmas spirit.

Advent 2016 is coming, do not to lose your chance to reserve a spot and spread your thoughts and love to F# with the community. Have you done something special this year? Do you have any unique experience you are willing to share? Have your project incredibly evolved this year? Are there any good ideas for the post, but you didn’t have time to write it? The time has come – it is right now! You have a chance to share your story with the globe! Join F# Advent Calendar and hurry up!

Rules

Rules are very simple:

1. Choose F# related topic for your blog post and reserve the date on Twitter or leave a comment to this post. Please note that you do not have to announce the topic until the date.
2. Prepare a blog post in English
3. Publish your post on a specified date (according to the calendar)
4. Post the link to your post on Twitter with hashtags #fsharp and #FsAdvent.
