4 years is the term of the Tweede Kamer, right? Therefore it is impossible for the government to last that long.

I don't think that's true, but I could be wrong? Could you elaborate?

(For reference: Rutte 2 was missionary for 4 years and a few months before they resigned)

Aha, gotcha thank you. I'd forgotten about the demissionary period. It's just that I find it slightly odd to say that the coalition "fell" if it lasts until the next election and then gets defeated. This is kinda different than "falling" in the sense that, say, NSC withdraws from the coalition and it thus loses the confidence of the current Kamer.

Also, what happens if the coalition falls afterJuly 3, 2027 but before July 1, 2028? It won't have fallen within 3 years, and it won't have lasted 4 years either.

I think it classifies as fallen if the cabinet offers its resignation to the king, and then a date needs to be found for new elections. In other words: there is a significant period of time where the cabinet is demissionary but no new elections have been held.

Would you agree?

That's a very good point, I didn't think about falling in the 4th year. I'll see if I can still add an extra option.

Looks like I might not be able to do that any more, sorry.

In other words: there is a significant period of time where the cabinet is demissionary but no new elections have been held.

Would you agree?

Yes, and in addition to that there's the period after the election is held and before the new government is formed. Does that count?

The period between the election and the formation of the new government does not count. This is (part of) the demissionary period and is after the prime minister has offered his resignation to the king (see description).
