This is how the World Cup does it: However, there's no info about the stages or anything. Literally this is the only thing that shows up in Advanced Rules.

Ok, then I'd have only 6 dates total (3 for the group stage matches and 3 for the quarter finals, semis and final)? In that case, when I choose a date to be an offset date, it's there when the stadiums rules come into play? Like in the image above, I have 4 dates for the same day, just with different stadium rules. If offset dates have to be in different days then it wouldn't make much sense to look for stadium rules since all matches could be played in the same stadium, right? The idea is for each group stage matchday to be played at the same time, for all groups, in different stadiums.

It's still scheduling the games one day after another, regardless of the fixture dates: Also, how would I scheduled matches in knockout rounds? I don't see how I can tell the game to pick specific dates from the fixture dates:

But it's a tournament with host, so only that host's stadiums should be there. How could I do that? I can't know which country will be the next host.

But I just can select a year and a stadium by name, nothing else. Stadium rules get greyed out.

Nope.

I don't have that in FM17. Here is the closest thing (I think), but the rules get greyed out if I select a stadium:

I can't find those "Stadium rules" you are talking about. I do have Stadium 0, Stadium 1, etc as options in stadiums.

I found that the issue only happens in group stages so it might be a stadium clash. I don't understand. I used the fixture dates as explained by rusty. Maybe I need to do it individually by group?

The fixture dates thing solved my problem with the Qualifiers. THey now run through 3 years without issues. However, I decided to use fixture dates for all the international competitions and now the National cups (AFC Cup and OFC Cup) crash on Dec 4th 2020. I checked and I think the issue has to do with the group stage matches. They are schedule in following days, like group A on 15th, group B on 16th, group A match 2 on 17th and so on. I set the dates in League Schedule (All groups) so all groups could play on the same day each matchday (all matchdays 1 on day X, all matchdays 2 on day Y, etc). Maybe it has to do with the stadium rules? They are all set to Host.

Nevermind, I managed to fix almost everything by removing the Qualifiers from the WC requirements tab. The only thing left for this to be perfect would be for the game to actually follow the calendar I made for the Qualifiers. I set it up so the games are spread over 3 years. However, they all get played in the first 14 months. Is there a way to re-do all international dates in custom form? Like, choose which dates have to be considered valid for international matches? Thanks.

Nope, just that. There are pictures above.

Qualifying is fine, I'm just testing with them being 10-team league stages, where the top 5 qualify, except for UEFA and CONMEBOL, that qualify the top 6. They show up as qualified in the summary screen for the WC. I've been testing several combinations for the WC and the Qualifiers and, so far, only 2020 for the WC and 2019-20 for the Qualifiers seem to work.

Both files (the one that works with the WC in 2020 and the one that doesn't, with the WC in 2022) throw the same error if a test them: "Match date for WC lies outside date range for the competition". Maybe 2022 is hard-coded somehow, even after deleting everything.

You know what? That make it all work (sort of). I have the WC scheduled to be played every 4 years, starting in 2022 (I was using 2020 as of now, so I didn't need to simulate so much), however, for some reason it doesn't want to start (same as before). I checked and there shouldn't be any conflicts. The Qualifiers are set to run from 2019 to 2021 (although they end in 2020), the national cups are scheduled for 2016 and the Confederations cup on 2017. All with a 4-year interval and 2000 as Base Year For Dates. Just changing the Year from 2000 to 2002 and the Start Year from 2020 to 2022 for the WC makes it so it doesn't get scheduled.
