Daylight saving time (DST; also summer time in British English) is the practice of temporarily advancing clocks so that afternoons have more daylight and mornings have less. Typically clocks are adjusted forward one hour near the start of spring and are adjusted backward in autumn. Modern DST was first proposed in 1895 by George Vernon Hudson.
During this weekend, the night of Saturday 27 to Sunday 28 March, we advance the clocks one hour: at two o’clock will become three, to adapt to daylight saving time. Núñez i Navarro Hotels will be remembered by notices in the reception of our new hotel in downtown Barcelona.
An early goal of DST was to reduce evening usage of incandescent lighting, formerly a primary use of electricity. Although energy conservation remains an important goal, energy usage patterns have greatly changed since then, and recent research is limited and reports contradictory results. Electricity use is greatly affected by geography, climate, and economics, making it hard to generalize from single studies.
