How the days are counted

183 days over twelve consecutive calendar months, counting part days and the days of arrival and departure. If you reach it you are resident from the day you arrived, not from day 183. The law counts whole calendar months; we use twelve months back from today, which at most warns earlier.

You are also resident if you have a home there, with no days counted, so the count does not decide on its own.
