Set an Alarm for 7:15 AM
Nobody picks 7:15 out of the air. It is an arrived-at time — the residue of months of trial and error, of discovering that 7:00 left you standing around and 7:30 left you sprinting. The field above already carries 07:15.
That is a compliment to the number, incidentally. Alarms tuned by experience beat alarms chosen because they were round.

Odd times are harder to argue with
7:00 has a fuzziness to it. Half past six is “nearly seven”, twenty past is “basically seven” — round numbers attract rounding, and rounding is how a wake-up time quietly drifts by twenty minutes over a season.
7:15 has none of that give. It reads as a calculated time rather than an aspiration, and calculated times get obeyed. It is a small thing, but it is a real one.
What fits into the 45 minutes before 8:00
A realistic accounting, not an optimistic one: five minutes to actually get out of bed and stop being horizontal, ten in the shower, five to dress, ten for breakfast standing up or sitting down, ten to pack the bag, find the keys and put shoes on. That is forty. The remaining five are the ones that absorb the missing charger, the spilled coffee, the last-minute text.
If your list is longer than that — hair that needs drying, a lunch to make, a dog to walk — 7:15 is not your time and no amount of hurrying will make it so. Add the minutes to the front, not to the panic at the end.
Bedtimes for a 7:15 AM wake-up
| Sleep length | Fall asleep by | Go to bed by |
|---|---|---|
| 9 hours | 10:15 PM | 10:00 PM |
| 7 hours 30 minutes | 11:45 PM | 11:30 PM |
| 6 hours | 1:15 AM | 1:00 AM |
What the quarter hour is worth in each direction
Against 7:00, this is fifteen minutes of continuous sleep you keep every working day — a bit over an hour across the week, taken in the most useful place possible, at the end of the night rather than the start. Against 7:30, it is fifteen minutes of morning that is not spent hurrying, which is a different currency but not a lesser one.
Both are real. Which one you want back is the entire question, and the answer changes with the season, the job and the year — so it is worth re-asking occasionally rather than inheriting last year's alarm forever.
