Going to bed for a 6:13 am alarm

  • Asleep by 8:58 pm — 6 full sleep cycles, about 9 hours
  • Asleep by 10:28 pm — 5 full sleep cycles, about 7 hours
  • Asleep by 11:58 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

As you finish getting ready and leave for the start of your shift at Smithfield Market, a 6:13 am alarm gives the morning a firm departure point. It leaves 47 minutes before 7:00 am, enough for the journey and the final walk towards the market without treating the round hour as your actual starting signal.

Because this alarm runs in the browser, set it on the phone or computer that will remain active until 6:13 am, then check that the volume is clearly audible. If that machine falls asleep or the page is no longer running, the Smithfield shift could begin without the alarm sounding. Leaving the alarm visible and connecting the device to power can prevent an automatic sleep setting from quietly interrupting it.

Stepping outside for Smithfield before the wider morning rush can mean meeting damp air, especially after overnight rain or mist. At this early hour, keep a light outer layer within reach rather than packing it underneath everything else; the humidity may make the walk feel clammy even when the temperature seems mild. A quick look outside before leaving also helps decide whether a breathable jacket is more useful than a heavier coat.

Common questions

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.

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.
