How to use the online alarm clock
Finish what you are doing and leave when the 6:30 pm alarm sounds, giving yourself time to reach the parents’ meeting with the teacher without a last-minute rush. If the journey is short, the half-hour before 7:00 pm can cover packing away, collecting your coat and checking the classroom or reception details.
Before relying on the alarm for the teacher meeting, check where its sound will play. Wireless headphones may still be connected even after you have put them in a bag, sending the alert somewhere you will barely hear it. Disconnect them or test the volume through the phone or computer speakers. The meeting reminder will not sound after the browser is closed or the phone or computer falls asleep, so use a separate alarm as a backup if you may stop using the screen.
Leaving at 6:30 pm can place the meeting between the working day and whatever follows that evening. Note the next commitment before setting off, then allow a small buffer after speaking with the teacher; conversations can run beyond the allotted slot, and corridors or the school gate may be busy. Keeping that margin means the next part of the day does not depend on finishing at an exact minute.
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.
