Going to bed for a 6:06 am alarm

  • Asleep by 8:51 pm — 6 full sleep cycles, about 9 hours
  • Asleep by 10:21 pm — 5 full sleep cycles, about 7 hours
  • Asleep by 11:51 pm — 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.

How to use the online alarm clock

Getting ready now for a 6:06 am start leaves room to check the tide table, pack a small net and find the boots before heading out to hunt for rock pools. The alarm can mark the moment to leave, while 7:00 am remains a useful reference for judging how much exploring time the morning allows. Keys, towels and a change of socks can be placed together beforehand, avoiding a hurried search while everyone else is still waking.

For this rock-pool departure, the alarm works while its page stays open and the computer or phone remains awake. Closing the page or browser cancels that browser session, so no sound will mark the trip to the rock pools; a sleeping phone or laptop may also stay silent. Keeping the page visible and the volume audible makes its status easier to check before departure. A separate built-in alarm provides sensible backup if the screen might lock while coats and bags are being gathered.

Before an early coastal outing, a light breakfast that is easy to finish can fit better than a large cooked meal. Water or a warm drink can go into a secure flask, with another bottle packed for later. Rich food is easier to leave until after the shoreline visit, especially when bending over pools and walking across uneven rocks. A wrapped snack in the bag covers the return journey without delaying the 6:06 am departure.

Common questions

Can I use this on a phone?

It works in a mobile browser, but phones lock the screen and suspend background tabs far more readily than a laptop does, which can stop the alarm sounding. For anything important, a desktop or a plugged-in laptop is the steadier option.

Does the alarm still work if I close the tab?

No. Everything runs inside this page, so closing the tab — or quitting the browser altogether — ends the countdown there and then. Leaving it open in the background is all it asks, and switching to another tab makes no difference.

What happens if my laptop goes to sleep before 6:06 am?

The tab sleeps along with it and the alarm will not sound on time, if at all. If you are relying on it, change the power settings so the machine stays awake, or keep a phone alarm running as well.

Do I need an account or an app?

Neither. Choose a time and a sound, press Start, and it runs in this browser tab. Nothing is downloaded, nothing is registered, and closing the page leaves nothing behind on the device.
