The Ultimate List of 2019 Advent Calendars for Designers and Developers
Tags: discuss, adventcalendar, collection
Published: 2019-11-30 22:28:02

The end of the year is fast approaching. 'Tis the season to be jolly and generous and what better gift to give than knowledge? It's already an established tradition for the web design and development community to create and publish advent calendars. So I decided to put together a list of the most popular websites that participate in this event. 

I'm going to update this collection over the next few days as this year's editions start getting online. The entries don't follow a specific order - I am just adding them in the order I've discovered them.

Do you have an advent calendar you follow that I haven't included? Please mention it in the comments area below and I will place it in the lineup.

Last update: December 8th

## The Third Annual C# Advent

This calendar is organized by our fellow DEV member, [Matthew D. Groves](https://dev.to/mgroves). And it's done in a different way because the posts are not published in a single location. Instead, they are aggregated on a single page but hosted in many other places
