Web Development Advent Calendars for 2020

Web developers around the world have celebrated Saturnalia solstice Isaac Newton’s birthday Christmas with advent calendars covering web-related topics. As a result, you may recognize some of the ones listed below.

Every year I miss a few on day one, so add a comment or tweet me if you have more to add.

Many of the regulars are skipping this year, citing the pandemic and probably not wanting to sit in front of their computers for even longer.

Lean UXmas (@LeanUXmas)

Lean UXmas collects the most popular articles from the Agile & Lean UX News mailing list, presented throughout the month.

24 Days in December (@24DaysInDec)

24 Days in December is a PHP-specific advent calendar. It looks like its goal is to give back to the same community from which the author has learned, which is a good metaphor for the holiday.

Advent of Code (@ericwastl)

Advent of Code provides a small programming puzzle every day up to Christmas. They are stand-alone, but supposedly have a general theme. They also use different technologies so there is some variety as well.

24 Days in Umbraco (@24DaysInUmbraco)

24 Days in Umbraco is dedicated to the Umbraco CMS. Now in its ninth year (the calendar, not the CMS).

24 Jours de Web (@24joursdeweb)

24 Jours de Web is back (after skipping 2016) as an advent calendar for web folk. Written in French, it is clearly primarily targeted at French speakers, but a round of Google Translate will open it up to far more readers (like me).

Code Security (@ripstech)

Code Security Advent Calendar 2020 will give away a daily Java security challenge.

Performance Calendar (@perfplanet)

Performance Calendar hails this as the speed geek’s favorite time of the year, ostensibly because of the tips it has been offering each December since 2009. It isn’t just server optimizations you’ll find here, so don’t shy away because you’re not a system admin.

JVM Advent (@JavaAdvent)

JVM Advent is posting a technical article from various authors related to Java each day.

Perl Advent Calendar (@perladvent)

Perl Advent Calendar goes all the way back to 2000 (and back then looked a bit more like a traditional advent calendar, too) and has been dispensing tips for Perl developers ever since.

PWAdvent (@nic_o_martin)

PWAdvent will introduce a new progressive browser feature every day. Perhaps there will be some you did not know exist or can work on the web.

A11y Advent (@HugoGiraudel)

A11y Advent is Hugo Giraudel’s between jobs project. Each day they will post a tip that they suspect may be common knowledge to many.

Web Accessibility Advent Calendar (@kazuhito)

Web Accessibility Advent Calendar 2020 is in Japanese, and thanks to the wonderful powers of Google Translate, I can tell you that anything from poems to posts count as long as they are about accessibility: Webアクセシビリティに関する内容であれば、ガチネタでもポエムでも構いません。). If you know Japanese, I welcome any corrections. Related, if you want to see a calendar about accessibility that is not restricted to web topics, check out Accessibility Advent Calendar 2020 (some registration required?).
