Web alarm clock for 5:28 a.m.
As you finish sweeping the yard and head back inside, a 5:28 am alarm can mark the moment to put the broom away before the heat returns. That leaves the early chores settled well ahead of 6:00 am, while the air is still relatively cool. Keep your slippers and dustpan near the doorway so you can leave the swept area tidy without making another trip outdoors.
The right alarm sound depends on how quiet your surroundings are while you sweep. A soft tone may be enough if the neighbourhood is still hushed, while a more persistent sound can cut through rustling leaves, passing tricycles, or the scrape of a broom on concrete. Set the volume before stepping outside and place the phone where the alarm remains audible. The alarm will not sound if you close this browser page or let the phone go to sleep, so your yard sweeping could continue past the planned stopping time.
Coming indoors from the dim yard at 5:28 am can make a bright screen feel harsh. Lower the display brightness before you begin, then leave the phone face down or angled away while you work. When the alarm sounds, you can stop it without staring into a glaring screen as the morning light is only beginning to strengthen.
