Online alarm clock for 11:19 pm
Pack your towel, goggles and warm layer now so your late ocean-pool swim is ready before the 11:19 pm alarm is needed. Setting it ahead of time leaves you free to check the pool access, fill a water bottle and put your keys somewhere easy to grab. With 12:00 am approaching, the alarm can mark the moment to finish preparing and head out without repeatedly checking the clock.
Keep the alarm page visible while you organise your swimming gear, or leave it running in the background if you need another page briefly. Some browsers reduce activity on a background page, particularly when battery-saving settings are active, so return once to confirm the alarm still shows as set and the volume is audible. Your ocean-pool swim cannot rely on this alarm if the browser stops running or the phone goes to sleep; use the phone’s built-in alarm as a backup if missing the departure time would matter.
Leave a small buffer after the swim rather than assigning every remaining minute before midnight. At 11:19 pm, changing, drying your gear and getting home can take longer than expected, especially after a breezy evening by the water. Allow enough room before the next task to rinse salt from your goggles, put damp items aside and settle in without rushing.
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.
