Current support
TimeCalculator.dev is designed for keyboard and touch use as well as pointer input. Standard Tab and Shift+Tab navigation move through interactive controls. Enter submits calculator fields where an immediate calculation is useful, and arrow keys step supported numeric inputs. Calculator buttons and controls use touch targets at least 48 pixels high or wide in the shared interface.
Results are placed in polite aria-live regions so assistive technology can announce recalculations without moving focus on every keystroke. An explicit calculate action moves focus to the result where supported. Labels are associated with inputs, validation is reported in text, and invalid fields expose their state.
Visual and motion choices
Keyboard focus uses a visible high-contrast outline. The layout reflows for narrow screens, and form text remains at least 16 pixels to avoid forced zoom on common mobile browsers. A reduced-motion preference shortens animation and transition effects.
Decorative charts are marked aria-hidden, with the same values or conclusions provided in nearby text, labels, or data tables. Color is not intended to be the only signal for a result or validation error.
Known gaps and feedback
Accessibility is an ongoing review, not a claim of perfect compatibility with every browser, device, or assistive technology. If a control, explanation, or result is difficult to use, email [email protected] with the page URL, device or browser, interaction attempted, and what happened. Known gaps and reproducible barriers are welcome and will be prioritized for correction.
