> 183 means more than 183 days, so day 184 crosses the line. ≥ 183 means 183 or more, so day 183 already counts. Each country uses its own official wording.

The day count is one test of tax residency. Many countries also apply home, domicile, or centre-of-life tests, and double-tax treaties can override a day count. Each article links the official source. This is not tax advice.
