DatetimeBuddy is an all-in-one time utility web app. Working across time zones is a daily challenge for remote teams and developers — figuring out what time it is in three cities at once, or counting down to a product launch, shouldn't require opening multiple tabs. DatetimeBuddy puts everything in one clean, fast interface.
Features
Time Zone Converter
Search and compare multiple cities simultaneously. Each location shows the local time, UTC offset, and time difference relative to your reference city. Built to handle edge cases like half-hour and 15-minute offsets.
Countdown Timer
A precise countdown to any date and time, with support for custom labels. Useful for product launches, deadlines, event announcements, and personal milestones.
Tech Stack
Built with Next.js for server-side rendering and optimized SEO, TypeScript for type-safe data handling, and Tailwind CSS for the responsive UI. Deployed on Vercel.
Why Next.js?
SEO matters for utility tools — people search for "time zone converter" and "countdown timer" directly. Next.js enables fast initial page loads, proper metadata per route, and strong Core Web Vitals scores, making DatetimeBuddy easily discoverable in search results.
