Age Category Codes

Age category codes may appear on an attribute of a category, which can appear in event and drawDefinition elements within a tournament record.

See ITF Standard Codes for an explanation of the construction of age category codes.

Code Format​

Age category codes follow CODES standards and support several formats:

  • Open: OPEN - No age restrictions
  • Under (U): 18U or U18 - 18 and under
  • Over (O): 35O or O35 - 35 and over
  • Range: 10O-18U or U18-10O - Ages 10-18
  • Combined (C): C50-70 - Combined ages 50-70 (sum of team member ages)

Calculating Age Details​

A consideredDate is required for calculating ageMaxDate and ageMinDate, values which can be used to validate a participant entry into an event.

import { eventGovernor } from 'tods-competition-factory';

const { ageMax, ageMin, ageMaxDate, ageMinDate } = eventGovernor.getCategoryAgeDetails({
  category: { ageCategoryCode },
  consideredDate, // required - typically the startDate or endDate of a tournament
});

Example Usage​

// For an U18 event with tournament end date of 2024-12-31
const result = eventGovernor.getCategoryAgeDetails({
  category: { ageCategoryCode: '18U' },
  consideredDate: '2024-12-31',
});

console.log(result);
// {
//   ageMax: 18,
//   ageMinDate: '2006-01-01',  // Youngest eligible birth date
//   ageCategoryCode: '18U'
// }

Using in Events and Draws​

Age category codes are typically specified when creating events or categories:

import { tournamentEngine } from 'tods-competition-factory';

// Add event with age category
const event = {
  eventName: 'Boys U18 Singles',
  eventType: 'SINGLES',
  category: {
    categoryName: 'Boys Under 18',
    ageCategoryCode: '18U',
  },
};

tournamentEngine.addEvent({ event });

See the Events and Categories concept page for more details on how categories work with events and drawDefinitions.
