An analogue face running down instead of round. The second hand sweeps continuously, the minute hand tracks the hour, and everything meets at twelve when time is up. It doubles as a clock-reading teaching aid: children can watch the hands move against a countdown they can also see written out below.
A free analogue countdown clock. The hands sweep backwards toward twelve as the time runs out — useful for teaching clock reading and for anyone who reads hands faster than digits.
TimerHub calculates remaining time from an absolute finish timestamp, so missed browser callbacks do not create drift. Read the timing accuracy methodology and reproducible tests.

Frequently Asked Questions
Do the hands run backwards?
They run down, which looks like backwards: as the remaining time falls, the hands move anticlockwise toward twelve and arrive there exactly at zero.
Can I put this on a projector or smart board?
Yes. Press Fullscreen under the timer and the drawing fills the display at whatever size the screen allows. Esc exits. For a Chromecast or AirPlay setup, cast the browser tab and then go fullscreen on the source machine.
Can I embed this timer in my own page?
Yes. Every timer here has a copy-and-paste embed code that drops a working countdown into a class blog, a lesson page or a school site, with no account and no script tag.
Does it need an account or an app?
No. It runs in the browser with no signup, no install and no ads, which is what makes it usable on a locked-down school machine.
