Online alarm clock for 8:45 pm
Pause what you are doing at 8:45 pm and leave enough time to drive your teenager to their Sea Scouts meeting without a last-minute rush. The alarm marks the point when the current job needs to stop, while the 15-minute run-up to 9:00 pm gives you time to gather keys, jackets and anything they need to take.
If you have been listening through headphones, check where the alarm sound will play before relying on it. Audio can remain routed to headphones even after you set them aside, leaving the room unexpectedly quiet. Keep the browser alarm running and the screen awake; otherwise it may stay silent and the Sea Scouts meeting departure could be missed. A quick sound check at the volume you intend to use makes the alert easier to recognise.
Once the Sea Scouts drop-off is finished, avoid letting the remaining evening disappear into another long task. Put away what you need for the morning, choose a clear stopping point for chores or screens, and leave a little quiet time before bed. That keeps the 8:45 pm interruption contained and protects the sleep still available after the drive home.
