WorldBestClock.com is a free clock and timer suite made for classrooms: a giant clock you can project on the TV, count-downs and count-ups, a daily alarm, gentle (or loud!) period bells, date countdowns for exams and birthdays, and a world clock — all on one calm, colorful page.
Schools run on time: periods, recess, exams, deadlines, birthdays. We wanted one simple page a teacher can open in the morning, project on the classroom TV, and leave running all day. No accounts, no setup — just open the page and it works.
Everything runs in your web browser. Your bells, alarm and event settings are saved on your device only (using your browser's local storage), so the classroom computer remembers them tomorrow — without any login. All sounds are generated by the browser itself; no files are downloaded and nothing is uploaded.
Like all our classroom tools, WorldBestClock.com is free to use, with no accounts, no logins, and nothing to install. The site is supported by unobtrusive advertising and the kindness of supporters.
