Accessibility is the foundation.
Both light and dark modes are designed to support keyboard, touch, and assistive technology. No separate accessibility mode is required.
Evaluation in progressOur target
Applicable Section 508 requirements and WCAG 2.2 AA guide this work. Evaluation is ongoing; the site does not claim compliance or a completed accessibility conformance report.
Built in
Semantic landmarks, a skip link, visible keyboard focus, native theme selection and disclosure, readable layout, reduced-motion support, and system high-contrast styling. The converter has labeled date, time, and time-zone controls, with guidance for daylight-saving changes. Its comparison slider supports arrow keys and hour buttons; digital results accompany the decorative analog clocks. Date math, age, countdown, business days, date planning, date formats and Unix conversion use labeled native controls and readable results. Clock Playground offers number fields and buttons as alternatives to dragging. Calendar, light and relativity explorations include readable values and keyboard controls. Motion is user-controlled; live countdown announcements are limited to milestones.
Ongoing review
Manual screen-reader evaluation, including Safari with VoiceOver and Android TalkBack, real keyboard and touch checks, enlarged text/reflow checks, and assessment of every implemented feature remain important. Automated checks cannot establish compliance.
