Going to bed for a 6:16 am alarm

Asleep by 9:01 pm — 6 full sleep cycles, about 9 hours
Asleep by 10:31 pm — 5 full sleep cycles, about 7 hours
Asleep by 12:01 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.

How to use the online alarm clock

Some people set this for 6:16 am because their phone alarm gets silenced by early notifications; others just want a second, louder reminder. Either way, pick 6:16 am, choose a sound, press start, and leave the tab open. It'll ring at 6:16 am until you close it or hit stop.

Choose a sound before you press Start — something like a chime or a classic bell tends to work better than anything too gentle. Once it's running, the countdown happens right here in the browser, which means the tab needs to stay open in the background rather than being closed.

A browser alarm like this one is handy when your phone's on silent, charging in another room, or you just don't want to unlock it and get pulled into notifications. The trade-off is honesty: it only rings while this tab stays open, so it's not a replacement for your phone alarm on a trip where the laptop lid might close. On a 24-hour clock 6:16 am is written 06:16, and spoken aloud it's sixteen minutes past six in the morning. Timetables and rosters may show it as 06:16, and handwritten notes as 6.16 am. If you need it loud, turn the system volume up before you start: the alarm plays at whatever the device is set to.

Common questions

Can I change the alarm sound?

Yes, there's a short list of tones to choose from before you press Start. Pick whichever one you're most likely to actually hear — softer sounds are easier to sleep through than a firm chime or bell.

What happens once the alarm goes off?

It rings through your device's speakers on a loop until you stop it from this page. There's no separate app notification, so make sure your volume is turned up before you rely on it.

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.
