6:18 AM alarm preset — set it online in one click, with sound and snooze.
This preset page selects 6:18 AM so you can set the alarm faster. It's helpful for repeat schedules and for sharing a link that opens with the right time already chosen.
Once the alarm is active, keep the tab open for best reliability. When the target time arrives, you'll see an on-screen alert and hear the selected sound if your browser allows it.
Sleep-cycle suggestion (optional): if you’re using 6:18 AM as a wake-up alarm, many people feel better waking between ~90‑minute sleep cycles. A simple guideline is to allow ~15 minutes to fall asleep, then aim for 4–6 full cycles. For 6:18 AM, example lights‑out times are: 9:03 PM (night before), 10:33 PM (night before), 12:03 AM.
Time zone reminder: alarms depend on your browser and device rules. If you travel or daylight saving time changes, confirm your device time zone is correct before relying on a browser alarm.
A simple routine helps the alarm do its job without relying on willpower:
