About a 5:15 am alarm
A 5 am alarm suits early commuters, shift workers heading for airports and anyone fitting exercise before work. It is before dawn for much of the year, so a lamp or a sunrise-style light helps. A quarter-past time gives you a small buffer when you want a few extra minutes before a half-hour appointment. Many people choose it to avoid the crowd of alarms that go off on the hour, and it suits anyone who needs a slow, unhurried first fifteen minutes to get moving.
In London the sun is already up at 5:15 am in May, June and July. It is still dark, or already dark, at that time in January, February, March, April, August, September, October, November and December.
