Bedtimes for a 6:30 PM alarm
Waking mid-cycle is what makes an alarm feel brutal. Working back from 6:30 PM in 90-minute blocks — plus a quarter of an hour to drop off — gives these targets.
| 9:16 AM | 6 sleep cycles | 9 hours of sleep |
| 10:46 AM | 5 sleep cycles | 7.5 hours of sleep |
| 12:16 PM | 4 sleep cycles | 6 hours of sleep |
These are planning figures, not medical advice — cycle length varies between people and from night to night.

What is 6:30 PM in 24-hour time?
6:30 PM is 18:30 on a 24-hour clock, written 1830 in military and aviation formats. It sits 6h 30m after midday and 1110 minutes after midnight.
Will this 6:30 PM alarm work if I close the tab?
No. The alarm runs in the page, so the tab has to stay open, though it can be in the background and it keeps working without an internet connection once loaded. Bookmark the page and the 6:30 PM setting is restored when you open it again.
