How to use the online alarm clock
As you hand the Royal Mail parcel run over to someone else, an alarm for 11:19 am gives the new person a clear moment to leave rather than relying on a hurried verbal reminder. There are 41 minutes until 12:00 pm, enough time to confirm the collection details, pass across the parcel and check which Post Office or postbox they are heading towards.
Once responsibility for the parcel has changed hands, the alarm page can remain visible while other browser tabs are used for maps or collection information. A tab moved into the background may be slowed or paused by the browser, so keeping this page in view near 11:19 am reduces uncertainty. For the parcel handover, the alarm remains dependable only while its page is open and the phone or computer is awake; closing the page or allowing the machine to sleep can leave the Royal Mail collection reminder silent.
Whoever takes the parcel should allow for late-morning traffic rather than treating the map’s journey time as fixed. Around 11:19 am, town-centre roads may be busy with deliveries, shoppers and vehicles approaching lunchtime stops. Adding a few minutes for junctions, parking and the walk to the postbox protects the collection window, especially when the route reaches a high street or a Post Office counter.
Common questions
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.
What happens if my laptop goes to sleep before 11:19 am?
The tab sleeps along with it and the alarm will not sound on time, if at all. If you are relying on it, change the power settings so the machine stays awake, or keep a phone alarm running as well.
