How to use the online alarm clock
Four in the afternoon is when a British winter afternoon ends. In late December the sun sets over London a few minutes before four and over Glasgow earlier still, so this hour marks the point where the lights go on, the curtains close and the day feels finished several hours before it actually is.
It is a busy hour for children's activities — swimming lessons, football training, music practice, tutoring — all scheduled to begin once school is out and to end before the evening meal. Parents running two or three of those in an afternoon rely on the clock rather than on memory.
Sunday shoppers meet a deadline here too, since the six-hour trading window at large stores generally closes at four, and anyone who has left the roast potatoes until the last minute discovers it at about ten to. Office work tends to shift into wrapping-up mode around now as well, and for anyone dealing with colleagues in North America it is the hour their working day begins. Each minute from 4:00 pm to 4:59 pm has a dedicated page below.
