How the days are counted
Belgium has no day rule. You are resident if your domicile or the seat of your wealth is there, judged by the circumstances; being on the National Register raises a presumption you can rebut. The only 183 in the Belgian code is about non-residents' employment income, not about residence.
This counter is a gauge and decides nothing.
