Hi Product Hunt! 👋 I’m Shaojie. Date math is the worst part of programming. When a system promises "delivery in 5 business days" or "T+2 stock settlement", developers are forced to build and maintain massive databases of global holidays and exchange closures. It feels like herding cats. I built this API to completely decouple that messy logic from your main codebase. With one API call, you can: 🌍 Skip national holidays for 100+ countries. 📍 Skip regional/state-specific holidays (e.g., Bavaria, California). 📈 Skip stock market closures (e.g., NYSE, European Central Bank). I made it extremely fast and stateless. There is a generous free tier to play around with. I'd love to hear your feedback and know what country or market you'd like me to add next!
