Can months be displayed as numbers when using the birth date picker widget?

When using the birthday picker widget is there a way to display numbers for months instead of the name of the month? 

Hello,

If I understand your question correctly, you want to replace the month drop down field of the "Birth Day Picker" widget with number drop down field. Is that correct?

Unfortunately, it is not possible to achieve your requirement. You may like to use the "DateTime" field instead of the "Birth Day Picker" widget. Please check the screenshot below:

Hope this answers your query.

Do get back to us if you have any questions.

Thank you!
