Set Alarm for 5 AM

Set a wake-up time and get a live countdown, a looping generated melody, a full-screen notice and a blinking tab title when the moment arrives — right in the browser tab.

--:--:--

The alarm rings only while this tab stays open. Browsers may slow down timers in background tabs, so for exact timing keep the tab active or visible.

Browsers allow sound only after you interact with the page — pressing Set alarm is exactly that interaction, so the melody will play.

Result

This page opens the alarm clock with 5:00 already entered — press Set alarm and the countdown to five in the morning starts, targeting today if 5 AM is still ahead or tomorrow if it has passed. Waking at five is the classic move of early risers: a workout, a run or two quiet hours of focused work before anyone else is up.

The hard part of a 5 AM start is that the house is silent and one soft beep will not do. This alarm fires a looping generated melody, covers the screen with a wake-up notice and blinks the tab title, then repeats the melody every 30 seconds until you press Stop — hard to sleep through, impossible to miss if you are already shuffling to the kettle.

One honest condition: the alarm lives in this browser tab, so the tab must stay open (the computer must not be asleep either). Browsers can slow timers in background tabs, so if seconds matter, leave the tab visible. Pressing Set alarm doubles as the interaction that unlocks audio — after that, the 5 AM melody is guaranteed a voice.

Accepted Formats & Rules

  • HH:MM time input with automatic today/tomorrow targeting and a live hours:minutes:seconds countdown.
  • Looping WebAudio melody re-signalled every 30 seconds until Stop — generated, not an audio file.
  • Full-screen wake-up notice, blinking document title and a countdown mirrored into the tab title.

Key Benefits

✓ One honest requirement instead of hidden ones: keep this tab open and the alarm rings — no app install, no account, no notifications permission.
✓ You cannot miss the moment: a looping melody, a full-screen notice and a blinking tab title fire together, and the melody returns every 30 seconds until you stop it.
✓ The alarm sound is generated live by your browser's audio engine — pressing Set is the interaction that unlocks audio, so there is nothing else to configure.

Use Cases

  • • Need a wake-up alarm on a laptop because your phone is dead, lost or charging in another room?
  • • Working or studying late and want a loud, persistent signal at an exact time — with a full-screen notice you cannot miss?
  • • Napping at your desk and need an alarm that re-rings every 30 seconds until you actually stop it?
