Northwood Little League offers baseball for league ages 4-14. You may use the chart below or the age calculator on the official Little League website to determine your player's league age. 
For example, if your player was born on July 10, 2016, he or she is "league age 10" for the Fall 2025/Spring 2026 season.
The age determination date for a Little League Baseball player is the age of a player on August 31 of the current year through the following Spring season. NWLL divisions are grouped by league age to make the competition fair for all players.
