Times & Dates started as a personal project. Working remotely across teams spread from Cape Town to Singapore, the founder kept reaching for time-zone tools that were either broken, plastered in misleading ads, or running off data that governments had changed months ago. So he built what he actually needed: a clean, fast, trustworthy set of utilities that loads immediately and gets out of the way.
That first version had four tools. The current site has over twenty. Every addition came from a real situation: a colleague who needed to know when the New York market close overlapped with the Tokyo open, a developer who wanted to double-check a Unix timestamp without pulling up a terminal, a hobbyist astronomer asking when the next full moon would rise over a specific latitude. Real problems, real people.
My name is Dandre Noah, and I am the person behind Times & Dates. I am a software developer with roughly ten years of experience building web applications, primarily for clients operating across multiple countries and time zones. Scheduling, date math, and time zone conversions have been a constant part of that work, and getting them wrong has real consequences. A misread UTC offset can mean a missed client call or a delayed deployment. I have been on both sides of that mistake.
This is not a faceless media company or a content farm. There is no team of contractors writing filler articles here. The tools are hand-built, the data sources are documented, and when someone reports a bug, I read the message personally. The contact form on this site goes to an inbox I check every day.
Every tool on Times & Dates runs calculations directly in your browser. Nothing is sent to a server to be processed. When you enter coordinates for the sunrise calculator, those coordinates never leave your device. When you convert a Unix timestamp, the math happens locally. This approach is faster, more private, and means the tools work even on a flaky connection.
The data behind the tools comes from sources I trust. Time zone rules and UTC offsets come from the IANA Time Zone Database, the same database that powers every major operating system and programming language on the planet. Sunrise, sunset, twilight, moon phase, moon distance, and moonrise and moonset calculations all use the suncalc JavaScript library, which implements solar and lunar position algorithms based on work by the National Renewable Energy Laboratory and Jean Meeus Astronomical Algorithms. Public holiday listings come from the Nager.Date open API, which pulls from government sources by country.
Times & Dates is free to use and requires no account. Hosting, domain registration, and maintenance are covered by Google AdSense advertisements. I disclose this openly because I think it matters. The ads are served by Google based on the content of the page, not on any personal data I collect about you. I do not build user profiles. I do not sell data. I do not track you across the web.

If you have a question, a bug to report, or data you believe is incorrect, I want to hear about it. Reports of wrong holiday listings or outdated time zone offsets have led to real fixes on this site. Your message will not go to a support ticket queue. It comes to me.
