Decided to do the exact same thing for FIFA 17. Suprisingly, everything worked! All competitions, including World Cup, Euros and other Internanational tournaments work.
The following is almost the same as the comment by KFJ.(link above). I'll rewrite it here:
Go into Frosty Editor -> Legacy Explorer, search for "cmsettings" and export it by right clicking on it:

Open it whenever, I'll open it in Visual Studio Code, you can do so in Notepad as well, then press ctrl+F and search for "CALSTART_YEAR":

Change the value of xxxx in "CALSTART_YEAR = xxxx" to 2025, or any other year you want. Save the file and reimport it back into Frosty Editor.

Now, search "compdata" in Legacy Explorer, press on the folder and scroll down to see "settings.txt":

Export it out and open it, and search for "schedule_year_start":

Change the xxxx value on line "0,schedule_year_start,xxxx" to 2025, or whichever year you want(as you can see I already changed it).
Then, go search for "14,schedule_year_start", you'll see the line "14,schedule_year_start,xxxx", change the xxxx to 2026. This is to change the World Cup year start date(as you can see I already changed it):

Now, search "84,schedule_year_start", you'll see the line "84,schedule_year_start,xxxx", change the value of xxxx to 2028. This will change the start date of the Euros:

Now, search for "1578,schedule_year_start", you will see the line "1578,schedule_year_start,xxxx". Change the xxxx to 2028. This changes the start date of the South America Cup(COPA America):

Now, finally, save the file and reimport it back into Frosty Editor. Launch the game in Frosty and start a career. You career will now start in 2025, the qualifiers of international competitions will adjust automatically:

I'm also attaching the .fbmod file.
