Earth Hour

Earth Hour is a worldwide movement for the planet organized by the World Wide Fund for Nature (WWF). The event is held worldwide annually encouraging individuals, communities, households and businesses to turn off their non-essential lights for one hour, from 8:30 to 9:30 p.m. towards the end of March, as a symbol for their commitment to the planet. It was famously started as a lights-off event in Sydney, Australia in 2007. Since then it has grown to engage more than 7000 cities and towns worldwide. Today, Earth Hour engages a massive mainstream community on a broad range of environmental issues. The one-hour event continues to remain the key driver of the now larger movement.

Earth Hour 2015 was on Saturday, March 28, from 8:30 pm to 9:30 pm in each location's local time. Earth Hour 2016 will be on Saturday, March 19, from 8:30 p.m. to 9:30 p.m. during participants' local time.

History

Conception and start: 2004–2007

In 2004, confronted with scientific findings, WWF Australia met with advertising agency Leo Burnett Sydney to "discuss ideas for engaging Australians on the issue of climate change". The idea of a large scale switch off was coined and developed in 2006, originally under the working title "The Big Flick". WWF Australia presented their concept to Fairfax Media who, along with Sydney Lord Mayor Clover Moore, agreed to back the event. The 2007 Earth Hour was held on March 31 in Sydney, Australia at 7:30 pm, local time.

Earth

Earth /ˈɜːrθ/ (also the world, in Greek: Γαῖα Gaia, or in Latin: Terra) is the third planet from the Sun, the densest planet in the Solar System, the largest of the Solar System's four terrestrial planets, and the only astronomical object known to harbor life.

According to evidence from radiometric dating and other sources, Earth was formed about 4.54 billion years ago. Earth gravitationally interacts with other objects in space, especially the Sun and the Moon. During one orbit around the Sun, Earth rotates about its own axis 366.26 times, creating 365.26 solar days or one sidereal year. Earth's axis of rotation is tilted 23.4° away from the perpendicular of its orbital plane, producing seasonal variations on the planet's surface with a period of one tropical year (365.24 solar days). The Moon is Earth's only permanent natural satellite. Its gravitational interaction with Earth causes ocean tides, stabilizes the orientation of Earth's rotational axis, and gradually slows Earth's rotational rate.

Hour

The hour (common symbol: h or hr, h being the international form of the symbol) is a unit of measurement of time. In modern usage, an hour comprises 60 minutes, or 3,600 seconds. It is approximately ¹⁄₂₄ of a mean solar day.

An hour in the Universal Coordinated Time (UTC) time standard can include a negative or positive leap second, and may therefore have a duration of 3,599 or 3,601 seconds for adjustment purposes.

Although it is not a standard defined by the International System of Units, the hour is a unit accepted for use with SI, represented by the symbol h.

Etymology

The Middle English word ure first appears in the 13th century, as a loanword from Old French ure, ore, from Latin hōra.Hora, in turn, derives from Greek ὥρα ("season, time of day, hour"). In terms of the Proto-Indo-European language, ὥρα is a cognate of English year and is derived from the Proto-Indo-European word *i̯ēro- ("year, summer").

The ure of Middle English and the Anglo-French houre gradually supplanted the Old English nouns tīd (which survives in Modern English as tide) and stund. Stund is the progenitor of stound, which remains an archaic synonym for hour. Stund is related to the Old High German stunta (whence German Stunde, "hour, lesson"), from Germanic *stundō ("time, interval, while").

Dash Berlin

Dash Berlin is a Dutch trance music project created in 2007 by Jeffrey Sutorius, Eelke Kalberg and Sebastiaan Molijn. The front man of the group is the DJ Jeffrey Sutorius, the 10th most popular DJ in the world according to DJ Mag in 2013. Sutorius initially started playing drums influenced by his late father who was a drummer in a jazz band, before discovering electronic music. He worked at BPM Dance and Mid-Town Records specializing in vinyl, with both stores becoming meeting places for many established Dutch DJ's. Molijn and Kalberg, who were deejaying as Pronti & Kalmani at the time, have credited Sutorius as a vital source of inspiration for some of their biggest records during that time.

Kalberg and Molijn have been contributing to the international dance scene for over ten years, with award-winning and platinum-selling hits for dance acts such as Alice Deejay, Vengaboys, Candee Jay, Pronti & Kalmani and Solid Sessions. Their track "Better Off Alone" was one of the first trance records that became big in the United States and was later sampled by French superstar DJ David Guetta in his song "Play Hard" and one of America's biggest rappers Wiz Khalifa in his breakthrough record "Say Yeah". They also have been working together with DJ Sander Kleinenberg on classic tracks like "This Is Miami" and "The Fruit" and remixes for major artists such as Justin Timberlake ('Rock Your Body' Remix winning the award for 'Best Remix' at the Dance Star USA Awards), Janet Jackson, BT, Usher, N.E.R.D., Lenny Kravitz, Junkie XL, Röyksopp, Mylo and Annie Lennox.
