Going to bed for a 6:30 am alarm

  • Asleep by 9:15 pm — 6 full sleep cycles, about 9 hours
  • Asleep by 10:45 pm — 5 full sleep cycles, about 7 hours
  • Asleep by 12:15 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

As you hand over responsibility for opening the allotment gate, a 6:30 am alarm gives the next person a clear starting signal. It leaves half an hour before 7:00 am, enough for them to collect the key, reach the plot and open the entrance for anyone arriving to work on the beds.

For this gate duty, the alert needs to be audible even if the phone was left on silent overnight. The alarm page can be set for 6:30 am and kept visible, but the device volume and silent-mode settings still determine what the person hears. If the browser page is shut or the phone or computer goes to sleep, the gate-opening alert cannot sound, so a built-in phone alarm is a sensible backup when the handover cannot be missed.

Anyone taking the key at this early hour can prepare for the temperature change between an air-conditioned room or car and the allotment outside. During a UK warm spell, 6:30 am may offer a cooler window for unlocking the gate and checking access before stronger heat develops. Keeping the key and a bottle of water beside the handover note avoids extra trips between the cool interior and the plot.

Common questions

What happens if my laptop goes to sleep before 6:30 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.
