The search results provide information about different referendums and voting dates in different countries. If you are looking for information about a specific referendum vote, please provide more details. However, if you are looking for general information about when a referendum vote takes place, the answer depends on the specific referendum and the country in question.

For example, the search results show that Australia held a referendum vote on October 14, 2023. In the United States, the California Secretary of State website states that a referendum can qualify for the statewide ballot up to 31 days before an election. In Australia, the Constitution requires that a proposed law be submitted to the voters ‘not less than two nor more than six months after its passage through both Houses’ .

Therefore, the date of a referendum vote depends on the specific referendum and the country in question.
