# How do I set age restrictions on a program?

> Restrict registration by an age range or a date-of-birth window.

<Note>
  **Must know**

  * Turn on **Age Restriction** on the Requirements step, then choose one of two modes. At least one bound is required; leave the other blank for no limit in that direction.
  * In **By age** mode, eligibility is measured against the program's start date — or each session's own date for sign-up-per-class and drop-in programs — so a child can become eligible for later sessions.
  * Athletes with no birth date on file still appear in eligibility lists, but they must have a birth date recorded before they can check out.
</Note>

On the **Requirements** step, switch on **Age Restriction** and pick how you want to define it:

**By age.** Choose a **Unit** of Years or Months, then set a **Minimum Age**, a **Maximum Age**, or both. Years accept one decimal place (for example, 5.1), and months let you express fine ranges like 18–36 months. Because this mode is measured against a date, it shifts over time — Uplifter checks each athlete's age on the relevant reference date rather than a fixed cutoff.

**By birthdate.** Set **Born on or after** and/or **Born on or before** to define a fixed date-of-birth window. This mode never changes — a birth date either falls in the window or it doesn't — which is handy for competitive age groups tied to a birth-year cutoff.

Whichever mode you use, the check runs on your marketing site as families register, and it's re-verified at checkout so no one buys into a program they don't qualify for.
