Going to bed for a 9:24 am alarm

Asleep by 12:09 am — 6 full sleep cycles, about 9 hours
Asleep by 1:39 am — 5 full sleep cycles, about 7 hours
Asleep by 3:09 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 9:24 am

As you hand the bottle-return run over to someone else, set the alarm for 9:24 am so the changeover has a clear checkpoint. That gives you both a shared time for gathering the containers, confirming where they are going and sorting out keys or transport. With 10:00 am still ahead, the handover can stay brief without leaving the next person to guess what has already been done.

Bottles clinking in the boot, traffic outside or conversation at the return point can easily cover a quiet alert. Set your phone volume high enough for the surroundings and, if possible, place it nearby rather than in a bag or another room. Keep the browser active and your phone awake; otherwise the 9:24 am alarm may not sound, and the bottles could still be waiting when the other person expects to leave.

Once the return-point job changes hands, protect some of the remaining morning for whatever comes next that day. Allow a small buffer for a queue, unloading containers and getting back onto the road instead of treating 9:24 am as the start of a tightly packed sequence. A quick note beside the alarm about the next commitment can help you judge whether the handover needs to finish well before 10:00 am.

Common questions

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.

Will the alarm still ring if I close the browser tab?

No. The alarm only runs while this tab stays open — closing it, or closing the browser entirely, stops the countdown before it can ring. Keep the tab open in the background if you need it to go off later.
