When to use this form

Use this form whenever you need a quick, reliable age check based on a date of birth. Event teams use it to separate adult and child tickets, assign seating, and plan meals. For example, pair it with the Party RSVP form to route guests to the right options and pricing. Schools, camps, and sports leagues can set fair cutoffs using an event date or season start date. If you track attendees, connect the result to the Simple guest list form to mark minors vs. adults and reduce manual edits. You also save time on compliance by flagging anyone under a set threshold, such as 13, 16, 18, or 21.

Must Ask Calculate Age Questions

  1. What is your date of birth?

    This is the single source needed to compute age accurately. Asking for date of birth avoids manual age entry errors and keeps results consistent over time.

  2. Age as of which date should we calculate?

    The reference date changes eligibility, pricing, and compliance outcomes. Set it to today, an event date, or a cutoff to keep decisions fair and transparent.

  3. What age format do you need (years only, or years and months)?

    Some programs need finer detail for infants or youth brackets. Clear formatting prevents confusion when you share results with teams or export reports.

  4. Do we need to validate a minimum or maximum age?

    Automatic checks (13+, 18+, 21+) stop ineligible submissions and reduce review time. For alcohol service or restricted entry, your Banquet event order form can reflect approved counts.

  5. Which country or region rules apply?

    Age of consent, majority, and youth pricing thresholds differ by location. Capturing region helps you apply the correct rule set and any required notices.
