About Us
Welcome to Hours Calculator, a modern productivity utility built to make shift calculations simple, instant, and completely private.
Our Mission
Most time sheet calculators on the web today are outdated, heavily cluttered with disruptive third-party advertisements, and sluggish. We designed Hours Calculator to offer a premium, developer-grade alternative:
- Zero Friction: Calculations occur reactively as you type. No reload or calculate button required.
- Zero Tracking & Cookies: We respect your privacy. No personal data, tracking metrics, or analytics tools are stored or transmitted.
- Vercel-inspired Aesthetics: A clean, high-contrast, modern UI that works beautifully across all desktop and mobile devices.
Core Features
The calculator is equipped with robust utilities to handle real-world payroll needs:
- Midnight Boundary Crossing: Auto-detects and calculates overnight shifts (e.g. 10 PM to 6 AM) without requiring manual split rows.
- Visual Span Timeline: A dynamic SVG progress bar that maps out shifts and lunch break segments in real time.
- Local Shift Logs: Save, name, edit, and delete multiple shifts to compile weekly working hours.
- Wage Estimation: Compute gross estimated earnings immediately by adding an hourly rate multiplier.
Open Source & Technology
Hours Calculator is built as a static Astro-based site using Tailwind CSS. All data is persisted locally in your browser's localStorage, meaning your logs never touch our servers.
