Hello Product Hunt Community! 👋 I’m the developer behind Time and Duration Tools. As a software engineer, I noticed that most online time calculators on the web today are bloated, filled with invasive layout shifts, or run on laggy, decades-old server setups. I wanted to fix this user experience bottleneck. I engineered https://timeandduration.com to be a zero-dependency, ultra-lightweight web utilities suite that executes programmatic calculations entirely client-side. By deploying the application across global edge server networks, we locked in a sub-100ms loading speed with absolute flawless Google PageSpeed performance. Whether you are a freelancer auditing weekly hours, an HR manager counting business days excluding federal holidays, or a backend engineer decoding raw Unix timestamps, this toolkit is built to streamline your daily operations with high-precision math. The platform is 100% free. I’m incredibly excited to launch here today and would love to hear your thoughts, feature requests, or feedback on how I can further refine the UI/UX for your workflows! Thank you for the support! 🚀
