"He is counting the days."

[Jane-Chan20th]

I wrote "Hij bent aan telten de dagen" as an experiment and it was counted wrong.

Well yes, as it is not proper grammar. You could say these however:

• Hij is de dagen aan het tellen -'he is currently counting the days' (most likely would've been accepted as well)
• Hij (loopt, zit, staat, ligt, hangt) de dagen te tellen -'he is counting the days (while walking, etc.)'
• Hij heeft de dagen (lopen, zitten, staan, liggen, hangen) tellen -'he has been counting the days (while walking, etc.)'
• Hij is de dagen wezen tellen -'he has been counting the days'
