Going to bed for a 11:48 am alarm

Asleep by 2:33 am — 6 full sleep cycles, about 9 hours
Asleep by 4:03 am — 5 full sleep cycles, about 7 hours
Asleep by 5:33 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 11:48 am

Getting ready early for an apartment inspection at 11:48 am gives you time to gather your questions, check the address and note anything you want to examine closely. Set the alarm for the moment you need to leave or meet the agent, rather than relying on a quick glance at the clock. With 12:00 pm approaching, the reminder can keep those final preparations from drifting into lunchtime.

Your inspection reminder is only useful if the screen running it stays active until the selected time. A browser alarm cannot sound after its page has been closed, and a phone that falls asleep beforehand may stay silent, causing you to miss the apartment inspection cue. Keep the alarm page open, prevent the phone from sleeping, and leave the sound turned up. For a time-sensitive appointment, a separate phone alarm provides a sensible backup.

Arriving near midday can make an apartment look quite different from how it appears later in the day. Before heading out, note the morning light around your current location and think about which direction the property faces. At the inspection, check whether direct sun creates glare in living areas, whether rooms feel dim, and how balconies or nearby buildings affect the available daylight.

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.
