Accessibility Statement

Last updated: April 27, 2026

Timestamp Converter is committed to keeping its tools and reference pages usable by everyone, including people who rely on assistive technology. This page describes the standard we target, the features that support accessible use, the known limitations, and how to report a problem.

Conformance target

The site aims to conform to Web Content Accessibility Guidelines (WCAG) 2.1 Level AA. The interactive tool on the home page and the static reference pages (per timezone, per year, per cron expression, per language, per "days between" pair) are designed against this standard. We do not currently claim full WCAG 2.2 conformance, although several 2.2 success criteria are already met.

What is supported

• Keyboard navigation. Every interactive control on the converter (input field, Now button, Clear button, presets, copy buttons, theme toggle, timezone dropdown, date math, duration calculator, bulk converter) is reachable with Tab and operable with Enter or Space. There are no keyboard traps.
• Landmark navigation. Every page has a single <main> landmark with id="main-content" in addition to <header> and <footer> landmarks, so assistive technology users can jump past the header without a visible skip link.
• Visible focus. A 2px focus ring (using :focus-visible) is shown on every interactive element. The ring uses the site's primary blue, which has a contrast ratio above 3:1 against both the light and dark backgrounds.
• Screen reader labels. Icon-only buttons (theme toggle, copy buttons) carry aria-label text. The detected-format hint and the toast notifications use aria-live regions so updates are announced.
• Semantic structure. Pages use a single <h1>, properly nested headings, a <main> landmark, and form <label for> associations on every input.
• Color contrast. Body text and primary UI text meet the 4.5:1 contrast minimum against their backgrounds in both light and dark themes. Large headings exceed the 3:1 minimum for large text.
• Reduced motion. Animations and transitions are reduced to near-zero duration when the operating system reports prefers-reduced-motion: reduce.
• Responsive layout. The site reflows correctly at 320px wide, supports browser zoom up to 200% without loss of content or function, and uses tap targets of at least 44 by 44 CSS pixels on touch devices.
• Theme support. Light and dark themes follow the system prefers-color-scheme by default, with a manual toggle that persists across sessions.
• No autoplay or flashing content. The site has no audio, no video, and no flashing or strobing elements.

Keyboard shortcuts

Most controls follow standard browser keyboard behavior. A few worth calling out:

• Tab / Shift + Tab - move forward and backward through interactive elements.
• Enter - activate buttons, links, and the timezone dropdown.
• Space - toggle buttons (including the result-value pseudo-buttons that copy a value back into the input field).
• Esc - close the timezone dropdown when it is open.
• Arrow keys - move through options in the timezone dropdown when it is open.

Known limitations

We aim for WCAG 2.1 AA but the site is built and audited by a single maintainer, so the following gaps are known and being worked on:

• The custom timezone dropdown uses a role="listbox" pattern. Most screen readers handle this correctly, but native <select> behavior on some assistive technology / browser combinations may differ.
• Some long monospaced result values can overflow on very narrow viewports (under ~280px). They wrap with word-break: break-all, which is readable but can split mid-token.
• Code-snippet blocks on the reference pages do not currently announce a language label to screen readers; the visible heading above each snippet conveys the language.
• The site does not yet ship a "high contrast" theme separate from the dark theme. The dark theme already exceeds AA contrast, but a dedicated high-contrast palette is on the roadmap.

If you hit a barrier that is not in this list, please report it - real reports take priority over the roadmap.

Assistive technology tested

The home page and a representative sample of reference pages have been spot-checked with:

• VoiceOver on macOS Safari and Chrome.
• NVDA on Windows Firefox and Chrome.
• Keyboard-only navigation on Chrome, Safari, and Firefox.
• Browser zoom at 100%, 150%, and 200%.
• System "Reduce motion" enabled.

We do not run formal third-party audits. If your organization needs a Voluntary Product Accessibility Template (VPAT) or an audit letter for a procurement process, the Contact page is the right place to ask.

Reporting an accessibility issue

If you encounter content or a control that is hard or impossible to use with assistive technology, please email the maintainer. To help us reproduce the problem, include:

• The URL of the page where you saw the issue.
• A short description of what you were trying to do and what blocked you.
• The assistive technology, browser, and operating system you were using (for example: "NVDA 2024.1, Firefox 124, Windows 11").

Email: [email protected]. Accessibility reports are read first; you can expect an acknowledgment within a few business days and a fix or roadmap response within 30 days.

Compliance scope

This statement applies to the website at timestampconverter.net, including the interactive home page and all programmatically generated reference pages.
