One Clock for the Whole School Day
WorldBestClock.com gathers every timepiece a classroom needs onto one free page: a giant clock you can project on the TV, count-down and count-up timers for activities and tests, up to ten period bells with your own instruction messages ("Walk in twos!", "Hand in homework"), three alarm sounds from gentle chime to fire-drill school bell, a world clock for up to eight cities, and date count-downs that keep "7 days to Exam" glowing at the top of every page.
Everything you set — alarms, bells, dates, cities — is saved on your classroom computer automatically. Close the page tonight and tomorrow morning it remembers the whole day for you.
Made for Projectors and Busy Teachers
Tap "Project on TV" and the clock grows to fill the screen, readable from the very back row. Date count-downs appear on every tab so the deadline is never out of sight, and a friendly reminder rings days before the big day arrives — never freezing the page, never interrupting your lesson.
Set a screensaver after a few quiet hours and the clock turns into a gentle gateway to our other free classroom tools — handy when the projector idles through break time.
