An Etymological Dictionary of Astronomy and Astrophysics

A system of adjusting the official local time in some countries in order to provide a better match between the hours of daylight and the active hours of work and school. The “saved” daylight is spent on evening activities which get more daylight, rather than being “wasted” while people sleep past dawn. Although known also as summer time, it includes the spring season and nearly half of autumn.
