How to use the online alarm clock
Four in the afternoon is the children's activity hour. Swimming, football academies, music lessons, tutoring and everything else scheduled to begin once school and the worst of the heat are out of the way, and to finish before the evening meal. Families running two or three of those in an afternoon rely on the clock rather than on memory.
In winter it is also the beginning of the good part of the day. From November to March the light softens through this hour, the beaches and parks refill, and the difference between arriving at four and arriving at five is a full hour of usable outdoor time before sunset.
In offices it is the point at which the day starts being wrapped up, and for anyone dealing with the west coast of the United States it is the hour their morning has not begun yet — a reminder set here is often about sending something before it stops being useful. Each minute from 4:00 pm to 4:59 pm has a dedicated page below.
