In Germany, the age group classification of the German Football Association applies .
The key date for the age group is January 1st of each year. The game year (season) begins on July 1st of each year and ends on June 30th of the following year.
The youth soccer team plays in the following age groups  :
- G-Juniors ( Bambini / U7 ): G-Juniors of a season are players who have not or have not yet reached the age of 7 in the calendar year in which the game year begins. In the season / game year 2019/20 these are those born in 2013 and younger.
- F-Juniors ( U8 / U9 ): F-Juniors of a season are players who are or have reached the age of 7 or 8 in the calendar year in which the game year begins. In the 2019/20 season / game year, these are those born in 2011 or 2012.
- E-Juniors ( U10 / U11 ): E-Juniors of a season are players who are or have reached the age of 9 or 10 in the calendar year in which the game year begins. In the 2019/20 season / game year, these are those born in 2009 or 2010.
- D-Juniors ( U12 / U13 ): D-Juniors of a season are players who have reached or have reached the age of 11 or 12 in the calendar year in which the game year begins. In the 2019/20 season / game year, these are those born in 2007 or 2008.

- A-Juniors ( U18 / U19 ): A-Juniors of a season are players who are or have reached the age of 17 or 18 in the calendar year in which the game year begins. In the 2019/20 season these are those born in 2001 or 2002.
Mixed relays (boys 'and girls' teams) are permitted in the B-Juniors and younger division. Where the local conditions make it appear necessary, the responsible youth committee can allow game rounds with teams in which players of different age groups play.
In Austria the soccer players becomedivided into age groups, with January 1st being the reference date for the age and the maximum age being shown with a "U" in front of it. To be eligible to play in a U19 youth team, for example, one must have been born after December 31, 1989 (reference date: January 1, 1990) in the 2008/09 season. B. the cut-off date January 1, 2001. In the junior classes up to U14, girls play together with boys, but they are allowed to play one year longer. A girl who was only intended for the U 11 after the deadline is eligible to play in the U 10. Depending on the regional association (per federal state), however, a certain number of players no more than one year older may be used.
As a rule, the reserve teams are considered to be U23 (sometimes also U24) teams, although there are regionally different regulations regarding the participation of older players.
There are still regionally different regulations for league operations, as each national association issues its own guidelines. At the Vienna Football Association , for example, game results are only evaluated from the U11 championship onwards, but only from the U14 onwards are the results included in an overall table that decides on promotion and relegation for all of the club's youth teams.
There is no uniform league structure, although the youth centers or football academies of the Bundesliga clubs (with the exception of Kapfenberger SV ) play in an Austrian youth championship (TOTO youth league) in the U18, U16 and U15 age groups. In addition to the Bundesliga clubs LASK , FK Austria Wien , SK Rapid Wien , FC Red Bull Salzburg , SV Ried , SK Sturm Graz , SV Mattersburg , SCR Altach and SK Austria Carinthia , the second division clubs Wacker Innsbruck , Admira Wacker andSKN St. Pölten their youth teams for this league.
In Switzerland, soccer players are divided into the following age groups, with 1 January being the reference date for age:

- The use of juniors in a younger category is not permitted.
- Juniors of the younger age group in junior categories C, D and E can be placed in the next lower category.
- Mixed teams girls / boys are allowed in children's football (juniors D, E, F) and juniors C.
- Juniors B, C, D, E and F may not play more than one competition on the same day.
Due to the division into calendar years, children who were born late in the year play on average with older children than those born early in the year. This can lead to a disadvantage, especially in the youngest divisions, for example in promoting talent. 
If, as was previously the case, the children are divided up with the reference date July 1, the spring children would bedisadvantaged. On the other hand, there is also the objection that an exemplary training should not endanger the promotion of talent. In training, the children would always have to be encouraged individually according to their respective abilities. The problem in Germany could be more in the qualification of the children and youth trainers and in the still very widespread "performance record table status". In the youngest leagues in particular, it should rather be the case that the coach checks for each individual player at the end of the game whether he has achieved the goal of the season with regard to the training and development of the player. With this individualization, the alleged disadvantage in games against older and perhaps “superior” play partners would not play a role.
