Translation:December 21, 2017
there are so many options to write the same date (and they are all correct, actually!), and it is really silly from the side of moderators not to give us the example how we should write it down to answer correct. How you guys suppose us to guess? There's no telepaths on this planet yet. )))
"Falsehoods programmers believe about time" includes "Human-readable dates can be specified in universally understood formats such as 05/07/11," because that is a falsehood. People use a crapton of different date formats. And also, the American date format is, speaking as an American, incredibly stupid. Allow a wide variety of formats including several good ones, or use dropdown lists to answer this question.
I wrote 21-12-2017 (because apparently using a '/' as separation sign is for some reason wrong) and got this
'You missed a space. 21_12_2017'
Why won't a proper way to write out a date (with just numbers) be recognised?
It's not that difficult, I'd think dd/mm/yyyy dd-mm-yyyy
Maybe in the lesson overview a short note should be added about which ways to write out a date will be recognised and which won't be. It would be helpful to avoid getting unjust mistakes
