School Year Calendar Age Groups
Staring on August 1, 2026, Sublette United Soccer will transition to a school-year age group calendar for all programs. This change is part of a nationwide decision led by U.S. Soccer and its affiliated youth governing organizations, including US Youth Soccer. As a member of the Wyoming Soccer Association and US Youth Soccer, Sublette United is required to adopt this updated age group structure.
Age groups will shift from the traditional January 1–December 31 birth-year model to an August 1–July 31 cycle, which more closely aligns with school grade placement. This nationwide change is designed to better support player development, team continuity, and the overall youth soccer experience.

Why Is the School Year Calendar Used in Youth Soccer?
The school year model:
· Better aligns with academic calendars
· Supports social development among peers
· Improves player retention by allowing teammates to progress together through both school and soccer
How the School Year Calculation Works
To calculate your player’s soccer age, determine if they fall within the birthdate ranges listed HERE or use the U.S. Soccer Age Group Formation Tool HERE.
Example:
For the 2026–2027 seasonal year, a player born in October 2016 falls within the school year range of August 1, 2016 – July 31, 2017, placing them in the U10 age group for the 2026–2027 season.
NOTES:
We recognize that no single birthdate system perfectly matches all school calendars, and some players—particularly those born in August or September—may find themselves grouped differently than in the past. This is a nationwide system, not a club-specific decision, and all clubs within our leagues follow the same structure to maintain competitive balance.
A child can play up in age group but not down.
PLEASE NOTE: There is no change to age groups for the upcoming Spring 2026 season. Players will continue in their current age groups through the spring season, with the new structure taking effect on August 1, 2026.
