Graph of sunrise and sunset times for 2007
The horizontal axis is the date; the vertical axis is the times of sunset and sunrise
There is a bulge in the center during summer, when sunrise is early and sunset late
There are step functions in spring and fall, when DST starts and stops.
Clock shifts affecting apparent sunrise and sunset times at Greenwich in 2007.
DST has mixed effects on health
In societies with fixed work schedules it provides more afternoon sunlight for outdoor exercise.
Sunlight strongly influences seasonal affective disorder
DST may help in depression by causing individuals to rise earlier, The Retinitis Pigmentosa Foundation Fighting Blindness, chaired by blind sports magnate Gordon Gund, successfully lobbied in 1985 and 2005 for U.S. DST extensions, Clock shifts disrupt sleep and reduce its efficiency.
DST's clock shifts have the obvious disadvantage of complexity
People must remember to change their clocks; this consumes time, particularly for mechanical clocks that cannot be moved backward safely.
People who work across time zone boundaries need to keep track of multiple DST rules, as not all locations observe DST or observe it the same way
The length of the calendar day becomes variable; it is no longer always 24 hours
Disruption to meetings, travel, broadcasts, billing systems, and records management is common, and can be expensive.
A standing stone in a grassy field surrounded by trees
The stone contains a vertical sundial centered on 1 o'clock, and is inscribed "HORAS NON NUMERO NISI ÆSTIVAS" and "SUMMER TIME ACT 1925".
The William Willett Memorial Sundial is always on DST.
Some computer-based systems require downtime or restarting when clocks shift; ignoring this requirement damaged a German steel facility in 1993.
These problems are compounded when the DST rules themselves change; software developers must test and perhaps modify many programs, and users must install updates and restart applications
Consumers must update devices such as programmable thermostats with the correct DST rules, or manually adjust the devices' clocks.
