Corrections Policy

We want every calculator result and every guide on this site to be accurate. This page explains how to report an error and what happens after you do.

How to report an error

Email aroharadiance@gmail.com or use the Contact page. Please include the page URL, what you expected, and what you saw — the more specific the report, the faster we can confirm and fix it.

Review timeline

We aim to acknowledge correction reports within a few business days. Straightforward factual or calculation errors are typically corrected within one to two weeks; issues that require re-checking a formula against multiple worked examples may take longer.

Correction process

1. We reproduce the issue using the inputs you reported.
2. We check the underlying formula or content against its documented assumptions.
3. We fix the code, content, or both, and re-run the automated test suite for that calculator.
4. We update the page's last-updated date to reflect the correction.

Change-log rules

We don't silently change a published formula or worked example. Any correction that changes a calculator's output updates that page's last-updated date, and significant corrections are noted in the relevant guide.

What we can't fix

Our calculators are planning estimates built on general conventions, not personalized professional advice. Where a result differs from your specific tailor, fabric, or situation, that's expected variation, not necessarily an error — see the relevant tool's Assumptions and Limitations sections for what the estimate does and doesn't account for.
