For example, in Belgium, a form is sent between the first day of the eighth month and the fifteenth day of the fifth month before the elections and must be returned by the citizens concerned by the first day of the fourth month before the elections at the latest. In the case of Brazil, citizens have to register 180 days before the election. In the Republic of Korea, the registration period is between 150 and 60 days before the election. In the Czech Republic, voters may register up to 60 days before the election. In the Netherlands the corresponding period is six weeks, in Finland 46 days, in Estonia 30 days, in Spain 25 days, in Germany and Georgia 21 days and in Hungary 16 days. In Poland, however, it is only three days.  Where the periods in question are long, they are reduced in the event of early elections: for example, Belgian law stipulates that, where this is the case, all registration operations must be completed before the fifteenth day preceding the date of the election.
