Going to bed for a 7:28 am alarm

Asleep by 10:13 pm — 6 full sleep cycles, about 9 hours
Asleep by 11:43 pm — 5 full sleep cycles, about 7 hours
Asleep by 1:13 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 7:28 am

As you pack away your hi-vis and leave the construction site, set the alarm for 7:28 am so tomorrow’s early shift has a clear starting point. That gives you time to reach the gate, meet the other tradies and have your gear ready before 8:00 am, without turning the morning into a rush.

Before heading home, test the alarm once while you can still hear and adjust it. Check that the sound is distinct, the volume is high enough and the displayed time reads 7:28 am rather than pm. Because this browser alarm cannot sound after the page is closed or the phone goes to sleep, the construction shift could begin while you are still at home; leave the page active and keep the phone awake until it rings.

When an early site start follows a long day, work backwards from 7:28 am before settling in for the night. Allow for the drive, breakfast, boots and any time needed at the gate, then choose a bedtime that preserves the sleep left before the alarm. Put tomorrow’s clothes, keys and packed food together tonight so those 32 minutes before 8:00 am are used for getting to the site, not searching around the house.

Common questions

Can I use this on my phone instead of a laptop?

Yes, it works in a mobile browser the same way, but phones are more likely to lock the screen or sleep, which can stop the alarm from ringing. A laptop or desktop tends to be more reliable for this.

Can I set more than one alarm at a time?

This page is built around a single alarm at a time. For multiple alarms, open a separate tab for each one and set a different time in each, keeping every tab open until it's rung.

Why use a browser alarm instead of my phone's built-in one?

Mainly for reliability against silent mode, do-not-disturb, or a phone left charging out of earshot. It's a useful backup or a desk-based alternative, though it depends on this tab staying open rather than running in the background of your phone.

Is there a cost to use this?

No, it's free, with no sign-up and no limit on how many times you set it. It just needs the tab left open until the time you've chosen arrives.
