How Worklity develops and reviews its tools

Purpose of Worklity content

Worklity publishes practical calculators and guides intended to make common calculations easier to understand and perform. The site covers everyday mathematics, dates, measurements, finance estimates, and health-awareness or planning tools. Each page is written to explain what information a tool needs, what it returns, and the important limits on how its result should be used.

Worklity is the publisher of this site. It is an independent tools website, not a Government website, healthcare provider, financial institution, lender, land-record authority, or professional certification service.

Calculator methods and conversion rules

A calculator is built around a stated mathematical method, date convention, conversion basis, or published schedule. Where a formula is useful to visitors, the related page or guide explains it in readable form. Where a traditional unit can vary by region, the assumptions used by the calculator are stated instead of being presented as universal values.

Calculation code is kept separate from presentation where the architecture permits. This helps the same rule be tested without depending on the appearance of a page. Changes to a calculator should preserve documented boundaries, rounding rules, units, and special cases unless a verified correction requires otherwise.

Examples and automated checks

Worked examples are checked against the method used by the related Worklity calculator. Calculation engines with important boundaries or date behaviour use automated tests for representative values, invalid inputs, and edge cases. A successful test does not make a result an official record or professional opinion; it shows that the implementation behaves consistently with its documented rule.

Health-related information

Health pages are presented for information, screening awareness, or planning assistance. They use cautious language and should not diagnose a condition, determine treatment, assess medical fitness, or replace a qualified healthcare professional. When a health tool depends on a published schedule, threshold, or clinical method, Worklity identifies authoritative sources where appropriate and describes meaningful limitations near the tool.

A reference link means that the source informs the stated method or context. It does not mean the source organization has reviewed, approved, or endorsed Worklity. Worklity does not claim independent review by a doctor or other specialist unless that has actually occurred and is explicitly disclosed.

Finance, property, and official decisions

Finance calculators provide estimates based on the inputs and stated formula. They do not include every lender rule, fee, tax, rate change, or contractual condition and are not loan offers or financial advice. Land and measurement conversions are mathematical aids; deeds, surveys, registration records, and applicable official measurements remain the appropriate sources for legal or property decisions.

Sources and original explanations

Worklity prefers official Government publications, primary guidance, recognized standards bodies, and established professional organizations when a claim requires an external basis. Explanations and worked examples are written in Worklity's own words. We do not use a citation to imply affiliation or endorsement, and we avoid adding a source that does not support the nearby claim.

Reviews, dates, and updates

Pages are reviewed when a tool is created, when its underlying rule or source is updated, or when a credible correction is reported. A visible “Last reviewed” date indicates a deliberate content review rather than an automatically changing timestamp. Not every page displays a review date, and an older date does not by itself mean a calculator is incorrect; time-sensitive guidance should still be checked against the linked current source.

Corrections and user feedback

If you find a calculation error, outdated statement, broken source link, or factual issue, please use the Contact page or email worklity.contact@gmail.com. Include the page address, the input or text involved, the result you received, and a reliable source when relevant. Reports are reviewed before a change is made so that a correction does not introduce a new inconsistency.

Limits of online calculators

Online calculators simplify a defined problem. They cannot know all personal, clinical, contractual, legal, regional, or administrative circumstances. Results should be treated according to the limitation stated on each page and independently verified for important decisions. Worklity guides are general educational material, not a substitute for professional advice or an official record.
