who came up with the idea of daylight saving time
Daylight saving time George Hudson proposed the idea of daylight saving in 1895.[4] The German Empire and Austria-Hungary organized the first nationwide implementation, starting on April 30, 1916. Many countries have used it at various times since then, particularly since the energy crisis of the 1970s.
Daylight saving time in Australia Daylight saving was first used in Australia during World War I, and was applied in all states. It was used again during the Second World War. A drought in Tasmania in 1967 led to the reintroduction of daylight saving in that state during the summer, and this was repeated every summer since then. In 1971, New South Wales, Victoria,[16] Queensland, South Australia, and the Australian Capital Territory followed Tasmania by observing daylight saving. Western Australia and the Northern Territory did not. Queensland abandoned daylight saving time in 1972.[17]
