Traveling through your own country muliple times. How do I use inbound and outbound journeys?

First of all, thank you for the fast reply.
But wouldn’t my trip from Warsaw to Amsterdam be considered both an inbound and outbound journey at the same time, since while crossing Germany (my home country) along the way, I am entering and leaving it in the same day?  

Yes indeed, the Schrödinger’s cat of interrailing.

Luckily there is no rule on how that journey is achieved, nothing suggesting you can’t transit through your home country to make a stop off on your way home.

Again thank you so much for the help. 
 

But could you tell me exactly what you mean by „Luckily there is no rule on how that journey is achieved, nothing suggesting you can’t transit through your home country to make a stop off on your way home.“

So would the trip from Warsaw to Amsterdam be considered an inbound or outbound journey ? Or can I decide which one it should count as? 

When you have a Global Pass you can travel in your home country on a maximum of two travel days. During these travel days (00.00-23.59 CET/CEST) you can use as many trains as you like.

Ok so I could go from Warsaw to Amsterdam without it counting as an inbound and an outbound journey, because I will do it in one travel day right ?

i have a similar problem. I want to go from Stuttgart to Paris, then Paris to BRussels, then Amsterdam, then Copenhagen (which goes through germany), then stockholm, then stuttgart. how do i use my inbound/ outbound trains? theres no way for me to go across germany.

Yes, if you cross Germany on one travel day that will use one of your I/O days.

In this case, it's probably best not to use your pass in Germany from Stuttgart to Paris. You can book a reservation for a direct TGV/ICE for just €25 (€40 in 1st class). This includes the reservation and a ticket for the German part of the journey. You can book that here:

Do NOT check "Book seat only”. You can add a BahnCard, which gives some discount. Then select "Passzuschlag One Country Pass”:

That name is not entirely correct, since it is valid for any pass where you need a reservation plus a ticket for the German part of the journey.

You'll need to add the journey from the border to Paris manually.

Okay, that also means I won’t be allowed to stay in Hamburg for the night or else I’ll use both in- and outbound there correct? 

Correct. 

I just realised that this still wouldn’t work. Even if I keep my outbound (the one to go from Stuttgart to Germany), I will use an inbound to enter germany on the way from amsterdam to copenhagen. I will have to change trains multiple times on the way from Amsterdam to Copenhagen, including german trains. THen I will still have the outbound but no way to get back to stuttgart when I leave Copenhagen and want to go home. I hope this makes sense?

“no way to get back to Stuttgart” - not correct.

You can get back to Stuttgart by using your pass to the Danish/German border, and then buying a ticket from the border to Stuttgart.  Even then, you only need to do this if you have already used your 2 “own country” days.

Forget all about the words “inbound” and “outbound” as they are just a distraction.  You can use your pass in your own country on 2 days.  They don’t have to be at the start and finish of your trip, they don’t have to go “outbound” first and then “inbound”.

You could use both of your days to return home from different parts of your trip, or both days to leave your country on different parts of your trip.

Simplify your thoughts - you can use your pass in your own country on 2 days of your own choosing.  You decide which days and for which journeys.  Logically, you would probably use them for the 2 more expensive legs and pay for the ticket for the least expensive one.

does it count as a „own country“ day if I pass through it? Sorry for asking so many questions but I just want to make sure I understand it correctly. 

Just to sum it up: I’d have to pay for the German part of the trip from amsterdam to denmark?

That will count as 1 “home country day”.

No, as I proposed it, you'll pay for he German part of Stuttgart to Paris, and then you use 1 home country day for Amsterdam to Copenhagen and the other one to get back to Stuttgart.
