Online alarm clock for 7:45 pm
Waking at 19:45 gives you a clear cue to get up and prepare to drive your teenager to their Sea Scouts meeting. Rather than trying to judge the time while still groggy, use the alarm as the point when the evening starts moving. There are 15 minutes until 20:00, enough to get dressed, find the car keys and check that your teenager has their uniform and gear.
Your Sea Scouts departure could easily be missed if the alarm sound is quietly routed to headphones you are not wearing. Check the audio output before settling down, then set a volume you can hear from where you are sleeping. Leave the browser alarm running and keep the phone or computer awake: if either stops, no alert will sound for the Sea Scouts trip. A quick test tone can confirm whether the sound is coming from the speakers or disappearing into connected earbuds.
Getting into the car after waking can feel abrupt on a hot New Zealand summer evening. If the cabin has been sitting in the sun, allow a few minutes for the air conditioning to cool it before your teenager climbs in with their kit. Keeping water nearby and placing the keys beside the alarm screen also makes the 19:45 departure less rushed.
