Going to bed for a 8:35 am alarm

Asleep by 11:20 pm — 6 full sleep cycles, about 9 hours
Asleep by 12:50 am — 5 full sleep cycles, about 7 hours
Asleep by 2:20 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 8:35 am

Wrap up your park group workout when the 8:35 am alarm sounds, then gather your mat and water bottle before heading off. That leaves a comfortable window before 9:00 am for the walk home, a shower or the trip to work without turning the end of the session into a rush.

A park session may finish in a quiet stretching circle or amid conversation and nearby traffic, so match the alarm tone to what you will hear. A gentle sound can suit a calm cooldown with your phone close by, while a more persistent tone makes sense if it will sit inside a backpack. Set the volume before exercise begins and test it briefly outdoors. Keep the browser running and your phone awake: otherwise the alarm will stay silent, and you may miss the group’s finishing time.

Leaving the park at 8:35 am can shape how much sleep remains available later, especially after an early start. If tomorrow brings another morning session, note the time you need to leave home and work backwards to a realistic bedtime. Avoid treating the extra 25 minutes before 9:00 am as spare time for several errands; using it for the trip back and getting ready can keep the rest of the morning steady without borrowing from tonight’s sleep.

Common questions

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.

Does the alarm work if my laptop goes to sleep?

Not reliably. If the device sleeps or the screen locks, the browser tab pauses along with it, so the alarm may not fire on time or at all. Adjust your power settings if you're relying on this over a longer stretch.

Do I need to create an account or download anything?

No, there's nothing to sign up for and nothing to install. Pick a time and a sound, press Start, and it runs entirely in this browser tab.
