If you need to be at work by 10 AM, here's when to set your alarm, based on your commute and how long you take to get ready.

| Commute | Ready in 30 min | Ready in 45 min | Ready in 60 min |
|---|---|---|---|
| 15 min | 9:05 AM | 8:50 AM | 8:35 AM |
| 30 min | 8:50 AM | 8:35 AM | 8:20 AM |

How much traffic buffer for a 10 AM start?
Later starts let you miss the worst of the morning peak, so commutes are steadier. A 10-minute buffer covers most days.
Driving vs transit vs walking
- Driving: the most variable. Add the buffer above, and more in rain or snow.
- Transit: plan around the timetable rather than a buffer. Aim for the service that gets you in 5–10 minutes early, and count the walk to the stop.
- Walking or cycling: very predictable, so a 5-minute buffer is plenty.
When to go to bed
For a 8:35 AM alarm, fall asleep around 11:20 PM (9 h) · 12:50 AM (7.5 h) · 2:20 AM (6 h). These line up with roughly 90-minute sleep cycles plus about 15 minutes to drift off; 7.5 hours suits most adults.
