American marrying a Dane, question about Schengen rules

[trob]

I am a US citizen and I have plans to marry my Danish fiance in Denmark on the 21st of January, after which we're going to use the Sweden-method to get me residency. We're just trying to make sure we have everything figured out before it's too late to fix it if something goes wrong, and we recently realized that we might have a problem with Schengen visa rules.
I went to visit her in Denmark on the 20th of July, and as far as I understand it, since I didn't do any paperwork or anything it means I was there under a Schengen visa. I stayed in Denmark for 30 days, and then came back to the USA. I have not left the USA since I got back. Now we have our wedding planned and underway for the 21st of January, but we were reading about Schengen rules and realized that it says a Schengen visa is only valid for 90 days within a 6-month period, and after that 6-month period the visaholder must leave the Schengen area. This would create some problems since our wedding is on the 21st of January, right after my 6-months are up. I've already bought tickets to come to Denmark the 21st of December... does this mean I'd have to leave the country on the 20th when my 6-months runs out and then come back to start a new 6-month period?
If that is the case, do I need to go all the way back to the USA, my home-country? or would it be ok if I simply left the Schengen area for a day or 2 and stayed in some other country, then came back to Denmark?
I'm also wondering, if we moved the wedding forward a few days and had it, for example, on the 18th of January, and then immediately moved to Sweden and applied for residency, would I then immediately be living there under a different kind of visa and not have to worry about the Schengen time-limit?
Thanks in advance for any help, you guys are amazing. This is a wonderful site, and I would be completely lost without all your help. Thanks! Any help with this would be really appreciated.

Hi trob. I have answered your danish spouse about this issue already, so perhaps she can just translate and explain my answer to you. But in short there is no problem at all. It is only, if you wish to stay in Schengen for more than 90 days total, that your second entry need to be at least 6 month after your first entry. Since you have stayed 24 days already, your next stay must be 66 days or shorter, if you enter Schengen before 20. january 2012.

Is the american citizen need some visa to go in denmark?

Nope, and even you do not need to apply for visa to Denmark as an American citizen, the rules of how many days you can stay are still the same.
