I entered the Schengen zone on September 29th, 2016 and left on November 20th, 2016 spending 53 days in Sweden and Spain. Let's say I want to return to Europe.
I have 37 days left on my 180 day period which ends on March 29th, 2017. Can I go to Morocco before the 180 days expires, travel for a week, and return to Spain after March 29th and get a new stamp starting a new 180 day period during which I can travel in Europe another 90 days?
I read a comment that if you do this, after the second period expires, you have to stay out of the Schengen zone for 6 consecutive months. Is this correct?
