Zeitful is a free toolbox of time-zone converters, world clocks, meeting schedulers, and date utilities for people who work across borders. It is not a faceless content farm. It is built and maintained by one named person, and this page says exactly who that is and how the tools are kept accurate.
Zeitful is built, owned, and maintained by Vikas Dulgunde, a software engineer based in London, United Kingdom. Vikas has around six years of professional software engineering experience working with JavaScript, Node, and the web platform, the same stack Zeitful is built on. He writes the code, builds the calculators, authors the reference guides, and is the person who replies when you email team@palenebula.com. Connect on LinkedIn.
That is the whole team. There are no ghostwriters, no anonymous content contractors, and no AI-generated articles published under a made-up byline. When a guide on this site says something about how time zones, daylight saving, or date handling actually work, it is written by an engineer who has had to get those things right in production code.
Time and date handling is one of the classic places software gets quietly wrong: off-by-one-hour bugs around daylight saving, calendars that assume every year has 365 days, recurring events that drift twice a year, epoch timestamps interpreted in the wrong zone. Getting these right is ordinary, first-hand engineering work, and it is exactly the work Vikas does. The tools here are not summaries of other people's articles; they are the utilities an engineer would build for himself, made public and free.
First-hand expertise is also why the site stays narrow. Zeitful covers time, dates, calendars, and developer time utilities. These are areas where the author can speak from direct experience and verify the output by hand. Where a topic edges into law, medicine, tax, or HR, the page carries a plain disclaimer that the tool is informational and cites the official source rather than pretending to give professional advice.
Zeitful is made for distributed teams, freelancers, support leads, recruiters, travellers, families, and anyone else who has to translate dates across borders. The practical question is usually not "what is UTC?" It is "can I call Tokyo without making someone join at midnight?", "what weekday is this deadline?", or "will a daylight-saving change move this recurring meeting?" The site is organized around those jobs: fast calculators first, plain-language context second.
Time-zone calculations use IANA time-zone identifiers and the IANA tz database via well-maintained JavaScript date libraries (date-fns-tz), rather than hand-coded offset tables that go stale the moment a government changes its DST rules. Holiday pages are built from cited public sources where possible, including official government calendars, country statistics offices, and Nager.Date for country holiday coverage. Historical and calendar reference pages are written as guides, not generated keyword pages, so they can explain the edge cases that make time data difficult.
The standard is explicit source notes over unsupported certainty. When a tool depends on data that can change, such as public holidays, daylight-saving rules, or statutory deadlines, the page says what source was used and when the information may need rechecking. The full process is written up on the editorial standards page. If you see a missing city, an out-of-date holiday, or a confusing result, use the contact page so the underlying data can be corrected rather than only the wording patched.
