Hey Product Hunt! 👋 I built TimeShift after getting tired of opening a new tab every time I saw a time in an email or meeting invite that I needed to convert. The workflow is simple: select any time on any webpage → right-click → convert. That's it. No new tab, no searching, no copy-pasting into a converter site. A few things I'm especially proud of: - It shows the exact date ("22 Feb 2026 - Sunday") not just "next day" - critical for cross-timezone scheduling - 285+ cities covered, all with valid timezone data - searched "Sylhet"? It finds it - Zero data collection - everything runs locally in your browser Would love your feedback on what features to build next. DST warnings? Calendar integration? Multi-timezone world clock? Let me know what would make your workflow better!
