How to use the online alarm clock
Getting ready well ahead of a market-day departure makes a 9:16 am alarm a useful checkpoint, not a last-minute jolt. With the bags gathered, a shopping list written and the bus timetable checked, the alarm can mark the moment to put on a coat and head out. That still leaves the approach to 10:00 am feeling unhurried rather than wasted.
Before relying on the alert for market morning, test it once at the same volume and with the same headphones or speakers you expect to use. A short trial confirms that the sound is audible and that the browser has permission to play it. Keep the alarm page running and the phone or computer awake: otherwise the market departure may pass without a sound. After the check, reset the alarm for 9:16 am and leave the volume where the test proved suitable.
Market preparations at this point in the morning may overlap with breakfast, remote work or someone enjoying a quiet lie-in. Choose a signal loud enough to reach you without carrying through every room, and keep the phone close rather than raising the volume across the house. If another person needs the kitchen or hallway at 9:16 am, place packed bags by the door earlier so the alarm leads to a quiet, quick exit.
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.
