Going to bed for a 9:39 am alarm

  • Asleep by 12:24 am — 6 full sleep cycles, about 9 hours
  • Asleep by 1:54 am — 5 full sleep cycles, about 7 hours
  • Asleep by 3:24 am — 4 full sleep cycles, about 6 hours

A sleep cycle runs about 90 minutes, and most people take around 15 minutes to drop off. Waking at the end of a cycle feels easier than waking in the middle of one.

Online alarm clock for 9:39 am

Break away from the job you are finishing when the 9:39 am alarm sounds, then grab your keys and head to the site after the morning traffic has eased. That timing leaves a useful window before 10:00 am for getting into the ute, checking the route and leaving without turning the departure into a last-minute rush.

Keep this alarm running in the browser while you finish what is already in front of you, with the sound turned up enough to be noticed from across the room. If you close the browser, or your phone goes to sleep, the alarm may not sound, which could leave your trip to the site starting later than planned. A phone alarm is a sensible backup when the departure cannot slip.

Late-morning light can be bright on an Australian workday, especially when the screen is facing a window or catching glare. While waiting for 9:39 am, lower the screen brightness to suit the room and place the phone where the display is easy to glance at without staring into reflected sunlight. The alarm sound can do the main work, so your eyes do not need to stay fixed on the countdown.

Common questions

Is there a cost to use this?

No, it's free, with no sign-up and no limit on how many times you set it. It just needs the tab left open until the time you've chosen arrives.

Will the alarm still ring if I close the browser tab?

No. The alarm only runs while this tab stays open — closing it, or closing the browser entirely, stops the countdown before it can ring. Keep the tab open in the background if you need it to go off later.

Does the alarm work if my laptop goes to sleep?

Not reliably. If the device sleeps or the screen locks, the browser tab pauses along with it, so the alarm may not fire on time or at all. Adjust your power settings if you're relying on this over a longer stretch.

Do I need to create an account or download anything?

No, there's nothing to sign up for and nothing to install. Pick a time and a sound, press Start, and it runs entirely in this browser tab.
