We're closing fast to the end of 2020, and it's once again advent calendar season. I'm doing a roundup of the ones running this year, as I did twelve months ago. I'm going to update this list over the next week with any new entries that I can find, so be sure to come again later.
One of the surprises this year brings is the absence of some well-established names (at least at the moment I'm writing this). Some have made announcements, while others have just gone silent. See the end of the article for a second list of the missing calendars.
Do you know of another advent calendar for developers or designers? Please let me know at twitter.com/frontendnexus, and I will update the list. Or you can just drop a comment at the end of this article.
That's enough lollygagging! Let's get the show on the road!
