Going to bed for a 7:58 am alarm

Asleep by 10:43 pm — 6 full sleep cycles, about 9 hours
Asleep by 12:13 am — 5 full sleep cycles, about 7 hours
Asleep by 1:43 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 7:58 am

As you hand over the morning round, set the alarm for 7:58 am so the next person knows when to let the chickens out after sunrise. The timing gives them a clear cue just before 8:00 am, without relying on a shouted reminder across the yard. You can finish explaining which gate to use while they keep the release time in view.

Because this alarm runs in the browser, closing the page or quitting the browser can silence the alert and leave the chickens waiting inside. Keep the alarm page open until it sounds, and make sure the phone or computer stays awake with its volume high enough to hear from where the handover is taking place. If the other person is carrying the phone, confirm that the alarm is still visible before you step away.

Once the chickens are outside in the early light, avoid turning a bright screen towards your face while checking the time. Lower the display brightness to suit the dim yard, use a warmer colour setting if your phone offers one, and glance at the screen only when needed. Positioning it below eye level can also reduce glare from the pale sky as daylight builds around 8:00 am.

Common questions

What happens if my laptop goes to sleep before 7:58 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.

Can I change the sound?

Yes, there is a short list of tones to pick from before you press Start. Softer sounds are easy to sleep through, so a firmer bell tends to be the safer choice for anything early in the morning.

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.
