Editorial Policy
Every number on TimeFlow should be checkable. This page explains how we build tools and guides, what sources we use, and what happens when we get something wrong.
1. How tools are built
Each calculator is built from a stated rule, not from a copied answer: the Gregorian calendar and its leap-year rule, ISO 8601 week numbering, standard date arithmetic, and the time-zone data your browser carries (the IANA time-zone database). The rule is shown on the tool's page wherever it matters, so a reader can check the result by hand.
2. How guides are written
Every guide is 1,200+ words, written to answer the real question behind the keyword — with worked examples, the edge cases that catch people out (daylight saving changes, leap years, the International Date Line), and the limits of the answer stated plainly. We do not invent statistics, search volumes, rankings or traffic figures, and we do not present an estimate as a fact.
3. What we do not do
We do not copy content from other sites, we do not publish machine-generated pages without a human check, and we do not accept paid links or sponsored content that pretends to be editorial. See the Affiliate Disclosure.
4. Corrections
Time-zone and daylight saving rules change, and mistakes happen. When a reader reports an error, we check it against the published rules, fix the page, and note the correction. Corrections are a normal part of running a site about time — they are not hidden. Report one on the Contact page.
5. Review
Tools are tested with known answers before they go live — dates whose day of the week is known, conversions that can be checked against an official clock — and re-checked when time-zone rules change. Guides are reviewed against the same rules they describe.
