Related: How does the Schengen 90/180 rule work?

I am in Ukraine
I have 70 days left on my shengen visa
My 180 day period ends in 40 days
I want to travel to Spain for as long as possible
If I travel to spain right now, how long can I stay there?
40 days? Or 70 days? Or Do I have to take a plane home in 40 days and then a plane to Spain the next day to enjoy 90 more days? Seems nonsensical, right?

Morocco is close and they give a 1 day visa, can I visit it in 40 days, does this count as a 180 period reset?

This answer quotes

The 6 month (or 180 days to be precise) period starts on the day of the first entry into the Schengen zone (Note that the day of first entry means the day you physically arrive in the zone and not the day the validity of the visa starts). In that 6 month period, you can only stay in the Schengen zone for a maximum of 90 days, irrespective of whether you have a new Schengen visa issued by the same or a different Schengen country that is valid beyond this 6 month period. At the end of this 6 month period, a NEW 6 month period starts and you can again spend a maximum of 90 days in the Schengen zone, provided you have a valid visa. If your stay duration overlaps two 6 month periods, then you must individually satisfy the 90 day limit in BOTH periods. All following 6 months period will be calculated back to back from the date of the first entry, until you remain outside the Schengen zone for at least 6 months. When you stay outside for at least 6 months (continuously) and THEN enter the Schengen zone, the six month period again starts from the day of the entry. It would be as if you were entering the Schengen zone for the first time.

What does the "you must individually satisfy the 90 day limit in BOTH periods" actually mean? Does it mean that I must be 90 days in one and 90 days max in other visa, or 90 days in both visas combined or what?

But the link is not clear enough for me to understand.

I even read the official doc and used it's calculator, which seems to give off random numbers.

How am I supposed to follow the rules if no one seems to know them.

Edit: There is no such thing as a period overlap, it's just that you can't stay for more than 90 days in the last 180 days, that's the only rule.

    That answer specifically states "This answer is invalid for most people as of November 2013". You need to go back and read the accepted answer on that question. It is now a ROLLING 180 day period. – Doc Apr 26 '18 at 19:11

    Timo, you're not reading what is being written. The 180 day period NEVER ends. Today the period that matters is 180 days back from today. Tomorrow, it'll be 180 days back from tomorrow. It's a sliding 180 day window, not based on your visa or the date(s) you enter the region. – Doc Apr 26 '18 at 20:35

    Which number does the calculator give you? – Relaxed Apr 26 '18 at 20:42

    Timo: @Doc is correct. There's also another way of looking at it: there's a 180-day period that ends on July 15th. There's another one that ends on July 16th. So if, on August 11th, you've had 90 days in the Schengen area, and if all 90 of those were within the previous 178 days, then you must leave before midnight. If you had 89 days, and one of them was 179 days earlier, then you can stay until the 12th. You must check this every day. A consequence of that algorithm is that there's no way to stay for more than 90 consecutive days. – phoog Apr 26 '18 at 20:52

    "Every 180-day period" means that every day is part of 180 180-day periods. So August 27 is the last day of the period that starts on March 1, the 179th day of the period that starts on March 2nd, etc. Perhaps the word "overlapping" is better than "rolling." "can I stay until the 90 day period ends...?" No, there's no 90-day period. The 90 days is just a quantity of days. They needn't be consecutive; they aren't a period. If you can post your dates of entry and exit, we can post an analysis showing when you must leave and how different strategies can change that date. – phoog Apr 26 '18 at 20:56

Do I have to take a plane home in 40 days and then a plane to Spain the next day to enjoy 90 more days? Seems nonsensical, right?

Yes, it is indeed nonsensical. That's not at all the way it works. For starters, you can never ever leave and turn around to stay more than 90 days. At the end of a 40-day stay in Spain, there is only ever 50 days left, possibly less depending on the schedule of your previous stays. It's also possible that you would not be allowed to stay for 40 days at this point, again depending on exactly when and how long you have been in the Schengen area in the past months.

From your many comments, it seems you are engaging in a bit of wishful thinking and overestimating the number of days you are allowed to stay. The rules are indeed a bit complicated but if you cannot wrap your head around the many descriptions available on this site and elsewhere, use the calculator and trust it. It's going to disappoint you and suggest much lower numbers than what you expect/wish but that's not random.

  • Thank you for your answer but it somehow managed not to answer what I'm asking, I'm very sorry that I'm wording it so badly. Also I'd like to clarify that there is a big difference between trying to understand a concept and wishful thinking, I know that everyone uses the calculator and I can use it too, it gives me 70 days, but I'm worried that it's wrong because the 180 day period expires even though I didn't spend the 90 days. – Timo Huovinen Apr 27 '18 at 5:52
  • Here's an example: You enter on the 1st of Jan for 1 day, you then enter on the 29th of July. Can you stay for 89 days or 1 day? The 180 days have expired, while the 90 days haven't. – Timo Huovinen Apr 27 '18 at 5:52

    @TimoHuovinen You shouldn't get hung up on the 180-day period, it has no relevance. I can only repeat what phoog and Doc already stated but there is no such thing. What's happening in your second example is that by the time you reach the 89th day, the 1st of January is more than 180 days in the past so it doesn't count anymore and you still have one day left (90 - 89 you just spent in the Schengen area). – Relaxed Apr 27 '18 at 6:07

    In fact, if there are at least 90 full days between your last departure and your entry, you always have 90 days left (every day of your stay you have at least one day left as the older days gradually disappear from the 180-day window). So I am not getting the reasoning behind your first example at all but I can tell you you can stay 90 days. – Relaxed Apr 27 '18 at 6:09

    A bit thank you to everyone (this was driving me insane), the last explanation made it all clear to me, what I kept thinking was that the start of the 180 days was fixed on the first day of entry and would reset after 180 days or 180 days plus some amount of time. Now I understand that you can check your remaining days by checking how many days you've spent in the area in the last 180 days. – Timo Huovinen Apr 27 '18 at 18:35
