How to use the online alarm clock
While preparing for the parent-teacher meeting, set the alarm for 3:02 pm before gathering the school report, questions and anything else you want to take. That gives the afternoon a clear checkpoint rather than leaving you to watch the clock while getting ready. With 4:00 pm still ahead, there is room to finish what you are doing and leave at the time your journey requires.
Because this alarm is meant to protect your meeting plans, keep the browser open after setting it and check that sound is allowed. Closing the page or browser means the parent-teacher meeting alert will not play, and it may also be missed if the phone or computer goes to sleep. Leave the alarm visible, keep the device awake and use a normal phone alarm as backup if being late would cause difficulty.
Once the meeting preparation is sorted, think about how much sleep you want to preserve later tonight. A 3:02 pm alert is early enough to avoid pushing unfinished school notes into the evening: jot down the final questions now, pack the paperwork together and decide when to leave. Keeping those small tasks contained in the afternoon can make bedtime less crowded with last-minute checking.
Common questions
Can I change the sound?
Yes, there is a short list of tones to pick from before you press Start. Softer sounds are easy to sleep through, so a firmer bell tends to be the safer choice for anything early in the morning.
Will it still be right when the clocks change?
Yes. It reads your device's local clock, so the move between GMT and BST at the end of March and October is picked up automatically, as long as the computer's date, time and time zone are set correctly.
Can I use this on a phone?
It works in a mobile browser, but phones lock the screen and suspend background tabs far more readily than a laptop does, which can stop the alarm sounding. For anything important, a desktop or a plugged-in laptop is the steadier option.
Does the alarm still work if I close the tab?
No. Everything runs inside this page, so closing the tab — or quitting the browser altogether — ends the countdown there and then. Leaving it open in the background is all it asks, and switching to another tab makes no difference.
