Am I overstaying? Please help me!

[leandroab]

Hi everyone!
Can someone help me please? I am having a question and I really cannot figure it out.

I am Brazilian and I first arrived in Frankfurt and then Zurich on 22 September 2015. Then I left to UK on 30 October 2015 and returned to France on 6 November 2015. Then I left to Morocco from 14 November 2015 to 12 February 2016, when I returned to Spain.

The question is:
My entrance day in the Schengen zone was 22 September, so the 180 days period would finish on 19 March 2016.
On 19 March I will have only 85 days, less than 90 days.
So since I have already been 3 months out and since I have been using less than 90 days on my 180 days period, can I stay more in the Schengen zone? How long could I stay more and when should I leave?
The Schengen calculator is not working for me.
If you people can help me it would be extremely helpful!
Thank you so much
Leandro

See this sample Schengen 90/180 rule calculation that hopefuly will give you an idea how those dates really are calculated:
