Ultimately in a number of states the Constitution and/or the electoral law only provide the maximum term of the legislature and leave it to an authority – usually the Head of State, exceptionally the Speaker of Parliament - to fix the date of the elections before the expiration of that term. This is the case in Austria, Iceland, Denmark and the United Kingdom, and also in Croatia, Ireland and Slovakia. In these three states it is stipulated that a certain period has to elapse between the decision on the date of the election and the election itself. (Croatia: thirty days; Ireland: minimum seventeen and maximum twenty five days and Slovakia: hundred and ten days).
