Overlap: Time Zone Matrix

Overlap is a modern, high-performance time zone matrix built specifically for remote workers, distributed engineering teams, and global business travelers.

The intelligent calculation engine dynamically highlights the "Golden Window"—the exact shared hours where all participants are awake and working simultaneously. 📊 Synchronized 24-Hour Timeline Grid Scroll effortlessly across a unified 24-hour horizontal matrix. Pinned city headers, real-time UTC offsets, and a glowing live minute needle give you immediate clarity across every time track at once. 🎯 Interactive Work Hours Slider Drag and resize your preferred business hours with tactile 30-minute snapping. Instantly see how changing your availability impacts your global overlap window in real-time. ⚡ 100% Offline & Instant Zero remote API requests. Zero network lag.
