What are you most proud of, and what would you do differently next time?

I learn more about JS date object which helped me gain a better understanding of working with dates

What specific areas of your project would you like help with?

I want to implement input validation in my project, but I’m not sure how to do it. For example, in the 'days' input field, the user should not be able to enter a value greater than 31.

I would appreciate any guidance or code examples to help me achieve this functionality.

I’m currently learning web development as a self-taught developer
