About Date and Time

Date and Time is a collection of simple, free tools for answering everyday date and time questions. Our goal is to make date calculations as straightforward as possible.

Our Philosophy

Many date and time questions are simple, but the answers are often hidden behind complex tools filled with ads, popups, and unnecessary features.

Date and Time focuses on clarity. Each tool does one thing, shows the result immediately, and explains how it works. There are no accounts to create, no personal data collected, and no complicated interfaces to navigate.

How We Built This

All calculations are performed directly in your browser using JavaScript. Your data never leaves your device. We use the excellent date-fns library for reliable, accurate date math.

The site is designed to be fast, accessible, and work on any device. We prioritize substance over style—but we also believe good design makes tools easier to use.

What We Offer

• Countdown calculators (days until, weeks until, workdays until)
• Date difference tools (days between, weeks between, business days)
• Date information tools (age in days, ISO week numbers)
• Time zone utilities
• Shareable countdowns for events

Privacy

We respect your privacy. All calculations happen in your browser—we never see or store the dates you enter. We use privacy-friendly analytics (Plausible) that don't track you across the web or use cookies.
