Going to bed for a 11:35 am alarm

Asleep by 2:20 am — 6 full sleep cycles, about 9 hours
Asleep by 3:50 am — 5 full sleep cycles, about 7 hours
Asleep by 5:20 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 11:35 am

You’re halfway through a task when 11:35 am needs to pull you away for fasting tests at the laboratory. An alarm at this exact time gives you a firm stopping point, with enough room to pack what you need and leave before 12:00 pm rather than noticing the clock after midday.

Your laboratory appointment stays in view mentally even when the alarm page slips behind another app or browser tab. Set the sound, start the alarm and check that its page remains open while you continue what you were doing. If the tab is closed, or your phone or laptop falls asleep, no alert can play and the laboratory tests may be missed. Keeping the screen awake and the browser running gives the signal a chance to interrupt you as intended.

A late-morning trip can take longer once traffic builds around shopping strips, roadworks and busy intersections. For an 11:35 am departure cue, allow time for the actual route as well as parking near the pathology collection centre; the alarm marks when to stop working, not when to walk through the door. Checking the drive shortly beforehand can reveal a slower road and leave time for a practical alternative.

Common questions

Is this alarm accurate across daylight saving time?

It uses your device's local clock, so as long as your computer's time and date settings are correct, it'll adjust automatically when daylight saving time starts or ends.

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.
