Travel Holiday Checker - Check public holidays for your trip

First-time solo developer here! I built Travel Holiday Checker because I'm a meticulous planner who hates last-minute surprises. There's nothing worse than arriving at your dream destination to find everything closed for a local holiday you didn’t know about. I wanted a simple, no-signup tool that lets travelers quickly see if public holidays overlap with their trips — plus get tips on closures and local experiences. This is the very first version of the app — I'm excited but also a bit nervous. I'd love your feedback and ideas on how to make it more helpful, especially from seasoned travellers and fellow devs. Any suggestions are very welcome! Thanks for checking it out.
