As stated in the title, I do not know how to do that... I see only things arrange questions like "newest, votes, active"...Thanks in advance.
There is information regarding this in the How do I search? page.
You can do the following searches, for example:
will return all questions which were created from 2014-01-01 to 2017-12-31.
You can refine this to
for a precision of months, or
for a precision of days.
You can couple this with other criteria. (You will find that even small intervals of time yield a very high number of questions.)
