Collecting birthdates on your WordPress forms sounds simple, but a few smart settings make all the difference. In this guide, you’ll learn how to configure Auto Form Builder’s Date field to work perfectly as a birthday field. Open Auto Form Builder and create a new form or edit an existing one. In the left sidebar, find the Date field and drag it onto your form canvas. Click on it to open the field settings. Change the Field Label to something clear like “Date of Birth” or “Birthday”. Under “How to Display Dates”, choose the format that matches your audience. US style shows Month/Day/Year. Most other countries use Day/Month/Year. For international forms, the ISO format Year-Month-Day works universally. Pick the one your visitors will find most familiar. This is the most important part for a birthday field. You have two settings — First Allowed Date and Last Allowed Date. For a birthday field, leave the First Allowed Date empty or set it to a date around 100 to 120 years ago to cover all realistic birthdates. For the Last Allowed Date, click Today — this prevents users from selecting a future date, which makes no sense for a birthday. As an extra layer of protection, enable Block Future Dates. This completely prevents any date after today from being selected, making sure your birthday field only accepts real past dates. You can control what date the field shows by default. Choose from No pre-selected date which leaves it blank, Today’s date, Tomorrow’s date, or a Specific date you choose. For a birthday field, No pre-selected date is the best choice — you don’t want today’s date pre-filled in a birthday field. If your form requires users to be a minimum age — for example 18 or older — set the Last Allowed Date to exactly 18 years before today. This means anyone born after that date cannot be selected, effectively enforcing the age requirement. Add a Help Text message like “You must be at least 18 years old” so users understand the requirement upfront. Show Date Preview Chip is enabled by default and shows a human-readable date preview next to the input — for example “Apr 16, 2026” — which helps users confirm they selected the right date. No Weekend Selection is available if your use case requires weekday-only dates, though for birthday fields you’ll leave this off since people are born on weekends too. Always add Help Text below the field to guide your users. Something like “Enter your date of birth” or “You must be at least 18 years old to register” sets clear expectations and reduces errors. Once your birthday field is configured, click Save Form, copy the shortcode, and paste it on any WordPress page where you need the form. A proper birthday field is just a Date field with the right settings — the right format for your audience, future dates blocked, realistic date limits set, and clear help text for your users. Auto Form Builder gives you all of these options in a simple, visual interface with no coding required. Ready to collect birthdates?
