Set Alarm for 6:30 AM

This page opens the alarm clock with 6:30 prefilled — press Set alarm and the countdown to half past six starts ticking, scheduled for today if the time has not passed yet and for tomorrow otherwise. Half past six is the great compromise: school mornings, breakfast before the 7:30 bus, or the extra half hour that makes six feel civilised.

When 6:30 arrives the page makes itself unmissable: a looping melody generated by the browser's own audio engine, a full-screen wake-up notice and a blinking tab title, with the melody re-ringing every 30 seconds until Stop is pressed. On a school morning that persistence is the difference between one snooze and three.

The honest fine print: this alarm exists only while the tab is open, so set it on a machine that will stay awake. Browsers throttle background tabs, so keep the tab visible if half a minute matters. Audio is unlocked by the Set alarm click itself — no permissions dialog, no test sound needed.
