Age calculator app using HTML, CSS and JS

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

Hey there! I'm excited to share that I've completed the challenge, although it did take me a bit of time. I made some enhancements, including a feature that will greet you with a happy birthday if today's date matches your birthdate.

I tweaked the error message for the year input to be more user-friendly and set the starting year to 1700. Now, instead of saying "must be in the past," it simply states "must be a valid year." This adjustment covers a broader range, ensuring it works smoothly from the year 1700 and beyond.

What challenges did you encounter, and how did you overcome them?

I have a hard time coming up with a solution for calculating the age.

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

I need someone to test if the app I made is working correctly.
