Hey Product Hunt! 👋
I’m excited to share WorldTimeBase — a fast, privacy-first, 100% client-side global time and calendar toolkit.
Like many remote workers and developers, I was tired of existing world clock websites: slow load
times, bloated banner ads, paywalls for tracking more than a few cities, and unnecessary tracking cookies for simple time calculations.
I wanted something clean, instant, and completely private. Everything in WorldTimeBase runs directly in your browser with zero backend servers, zero tracking, and zero ads:
✨ What’s inside:
• ⏰ World Clock & Visual Timeline — compare team working hours across timezones with intuitive color coding.
• 📅 Global Meeting Finder & Shareable Links — find overlapping slots instantly and generate timezone-aware event links.
• ☀️ Day & Night World Map — interactive sinusoidal solar terminator with real-time solar noon &twilight calculations.
• 💻 Developer & Date Math Studio — Unix epoch converter with batch parsing, business day calculator, and year progress trackers.
• ⚡ Fast Navigation — full keyboard support (`Cmd/Ctrl + K`) to jump anywhere in seconds.
I’d love to hear your thoughts, feedback, and feature requests. What timezone headache should we tackle next?
