A roundup of Advent Calendar sites of interest to web designers and developers. From accessibility to UX, coding challenges to Perl, there really is something for everyone this December.

In the run-up to Christmas, there is a tradition across the web design and development community to produce advent calendars, typically with a new article or resource for each day of December. Last year, I did a roundup of these calendars, and now that the 2019 season is in full swing, here is this year’s line-up.

I’m sure you’ll notice that the majority of the calendars published here are true community efforts, often with the bulk of the work falling to an individual or tiny team, with no budget to pay authors and editors. So, please join us in supporting these efforts; share the articles that you enjoyed reading and join the discussions respectfully.

Whether you celebrate Christmas or not, you can certainly learn a lot of new things. (Large preview[2])

What follows is an amazing variety of calendars, taking different approaches to the idea of publishing something every day in advent. There are plenty of traditional articles, but also code challenges to get involved with. I’ve tried to locate RSS Feeds and Twitter accounts to make it easy for you to keep track of your favorites. Enjoy!

It’s A Shape Christmas[3]

It’s A Shape ChristmasIt’s A Shape Christmas is a digital calendar that counts down to Christmas and reveals a bespoke illustration each day themed around four different shapes (Square, Triangle, Circle and Hexagon) and Christmas. The project was started in 2011 by a UK design agency called Made by Shape. This year, it is showcasing some of the best of the previous seasons.

24 Ways[4]

24 Days In Umbraco[5]

24 Days In Umbraco24 Days In Umbraco is a calendar of articles relating to the Umbraco CMS. However, the themes of the articles so far this year will be of interest to more people than just those who use Umbraco. I enjoyed the article from December 2nd — Setting The Stage by Laura Weatherhead about public speaking.

Bekk Christmas[56]

React, JavaScript, Security And Elm ChristmasLast year, Norwegian company Bekk produced four calendars. This year, they are back with twelve! In a blog post[57], they explain why they are producing such a huge number of articles this year. I learned that there are over 100 authors from within the company — many of who have not written articles before. Therefore, in the lead up they have been taking part in writing workshops. Perhaps we will find some future Smashing authors among them!

The homepage for the project is at[58] where you can check out the topics that interest you most.

Share The Ones I Missed!

There seem to be even more calendars publishing this year than last, despite the fact that some are taking a break this year. It’s been nice to find some calendars in languages other than English, too! If you know of a calendar related to web design and development that I haven’t mentioned here, please post it in comments section below.

Enjoy your seasonal reading!
