Going to bed for a 9:27 am alarm

Asleep by 12:12 am — 6 full sleep cycles, about 9 hours
Asleep by 1:42 am — 5 full sleep cycles, about 7 hours
Asleep by 3:12 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.

How to use the online alarm clock

Waking at 9:27 am gives you a quiet moment to get up before showing the water meter to the water company’s representative. You have enough time to find the meter cupboard, clear anything blocking it and locate a recent bill if you need the account details. With the visit handled before 10:00 am, the rest of the morning can begin without a rushed search around the house.

While you get dressed or head downstairs, the alarm page may move into the background behind another app or browser page. The countdown should continue, but its display will no longer be in front of you, so leave the sound turned up and check that the browser is permitted to play audio. The alarm cannot alert you if its page is closed or your phone is asleep, which could leave the representative waiting while you are still upstairs.

A morning appointment can affect everyone at home, especially if the meter is in a shared hallway, kitchen cupboard or garden. Mention the 9:27 am alarm the night before, and ask housemates or family members not to lock an internal door or move the meter key. Using a moderate alarm volume also reduces the chance of waking someone who does not need to meet the visitor.

Common questions

Will it still be right when the clocks change?

Yes. It reads your device's local clock, so the move between GMT and BST at the end of March and October is picked up automatically, as long as the computer's date, time and time zone are set correctly.

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 9:27 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.
