As this article is being published, our team of judges are looking at the amazing submissions we received for our 2021 calendar. We say this every year, but we think this will be the best one yet!
So while you’re waiting to get a peek at the maps that are chosen, we thought we’d give you another way to build up the anticipation – a crowdsourcing project! So tell us: which “Special days” deserve to be marked in the 2021 GeoHipster calendar? PostGIS Day, obviously, and maybe a few other official holidays. But what else? Help us decide by voting in this fun poll. Suggestions welcome — comment or email to atanas.entchev [at] gmail [dot] com.

What about “GIS Day” – meaning, redefining it to a truly, ad-free day as it was meant when Jack proposed it.
And pls. stop promoting Shapefiles – it’s legacy considered harmful.

Added, verbatim as proposed, which stirred up some controversy on Twitter. I invite you to join the discussion there.
I don’t know what makes you think we promote shapefiles.

Goes without saying. PostGIS Day is in this year’s calendar as well as in the 2019 calendar. Not sure whether it goes further back than that.

Of course! No vote necessary. From the body of the post introducing the poll: “So tell us: which “Special days” deserve to be marked in the 2021 GeoHipster calendar? PostGIS Day, obviously, and maybe a few other official holidays. But what else?”
