The UEFA European Under-19 Championship consists of three distinct stages: the qualifying round, the elite round and the final tournament.
The qualifying round, played in autumn, is made up of 13 groups of four teams playing in one-venue mini-tournaments. The top two from each progress.
In the elite round, played in the spring, those 26 qualifiers join the top two seeds, given a bye, in seven mini-tournament groups of four. The group winners then join the hosts in the finals.
The seven qualifiers plus the hosts are split into two groups of four who play each other once, with the top two progressing to the semi-finals. The winners of those ties contest the final.
Further details, including the criteria for separating teams that finish level on points in a group, or after extra time in a match, can be found in the official competition regulations.
UEFA has confirmed the venues and kick-off times for Wednesday's UEFA European Under-19 Championship semi-finals in Tbilisi.
The first game, at the David Petriasvilii Stadium, will pit Group A winners Portugal against the Netherlands, the runners-up in Group B, kicking off at 17:00 local time (15:00CET).
The second semi-final then starts at 20:00 local time (18:00CET) at the Mikheil Meshki Stadium with England, the winners of Group B, playing the Czech Republic, who finished second in Group A.
The winners of the two semi-finals will meet in Saturday's final, which will also be held at the Mikheil Meshki Stadium. That game kicks off at 20:00 local time (18:00CET). There will be a new name on the trophy this season with none of the semi-finalists having previously won the U19 prize.
