As answered by people managing CodeSandbox and TimeandTool.
TimeandTool's answer:
TimeandTool started from a simple problem — most time and date websites are either outdated or overloaded with ads. The idea was to build a cleaner, faster alternative that handles everything in one place, while also supporting developers and modern use cases.
TimeandTool's answer:
TimeandTool brings together multiple time and date use cases into one place instead of spreading them across different tools. It covers everything from timezone conversion and calendars to astronomy data and developer APIs. The platform is built for speed, works without sign-up, and focuses on making common time-related tasks quick and reliable.
TimeandTool's answer:
Most existing tools are either outdated, slow, or limited to a single use case. TimeandTool offers a faster and more modern experience with a wider range of tools in one platform. It also includes features like a public API and structured data support, which many traditional time websites don’t provide.
TimeandTool's answer:
TimeandTool is mainly used by people who regularly deal with time across regions. This includes remote teams, developers, travelers, and anyone who needs accurate time, date, or calendar information without wasting time switching between multiple tools.
TimeandTool's answer:
TimeandTool is built using modern web technologies including Next.js, a PostgreSQL database, and edge-based deployment for fast global performance. Timezone data is based on the IANA database, and astronomical calculations are handled using precise mathematical models implemented in TypeScript.
