About ChronoHub

ChronoHub builds fast, no-signup date and time calculators — days between dates, age, countdowns, time zones, and the everyday date math people search for. Every tool runs entirely client-side and is tested against worked examples before it ships.

Who runs this

ChronoHub is part of FreeToolbox, a small family of independent tool sites run by the same team. We link between them openly in the footer — they are sister sites, not a disguised network, and nothing here is sponsored placement dressed up as a recommendation.

How the tools are built and checked

Every tool implements a published, standard method — a formula, a specification, or a documented algorithm — rather than a rule of thumb. Where a page shows a worked example, the arithmetic in it is the arithmetic the tool performs, so you can verify the result by hand rather than take it on trust.

Nothing is a copy of another site. Each tool is written from the underlying method, with its own interface, its own explanation and its own examples. Where a result depends on an assumption — a rounding convention, a standard allowance, a population average — the page says so instead of hiding it behind a single confident number.

How the site is funded, and what that means for you

Advertising pays for the hosting. Ad units are labelled, kept away from the controls and results so nothing can be clicked by accident, and reserved at a fixed height so the page never jumps as they load.

What we do not do: sell your data, require an account, gate results behind a payment, or accept payment to rank one product above another. Where a page links to a commercial offer, it is marked as sponsored, every time.

Your data

The tools run in your browser. The values you enter are not transmitted to us, not logged and not stored, which is why results appear as you type rather than after a round trip to a server.

Corrections and contact

Accuracy reports come first. If a result looks wrong, or an edge case is handled badly, tell us what you entered and what you expected — we will check it against the underlying method and fix it. The same address works for anything else: support@freetoolbox.eu
