When is Daylight Saving Time in 2012

Though confusing, understanding the concept of Daylight Saving Time change is quite important if you happen to reside in some region wherein it is followed, or if you planning a visit there. In the following write-up we will put forth the details of the same whilst emphasizing on DST 2012.
The practice of Daylight Saving Time change can be a bit confusing, especially if you are new to some region which follows the same. Whether you happen to be a citizen of North America or whether you intend to visit some country there, being well-versed with its basics can be of great help for you. But all countries do not follow this practice, and those countries which do follow are also divided over the dates of time change.

The Daylight Saving Time (DST) change is a practice wherein time clocks are put forward by an hour during the spring season and reverted by an hour during the fall with the sole purpose of having longer afternoons - as they are believed to be more productive. The credit for the development of this concept is given to Vernon Hudson as he was the one who developed it into its modern form - a form which is widely accepted today. As clock timing is put ahead during the spring, the practice is also referred to as 'spring ahead' and as clocks are reverted by an hour during fall, it is referred as 'fall back'.

The concept is most popular in Europe, where it was developed, and North America. However, the two regions follow different dates when it comes to DST change. In Europe - where the concept is referred to as the European Summer Time, the last Sunday of March is chosen to 'spring ahead' and the last Sunday of October to 'fall back'. On the other hand, in North America - including the United States of America, the second Sunday of March is chosen to 'spring forward' and the first Sunday of November to 'fall back'.

The concept also differs in accordance to hemispheres as well - in the Northern hemisphere, it begins in March or April and ends in September or October, and in the Southern hemisphere, it begins somewhere in September or October and ends in March or April. In Australia, the first Sunday in October is chosen to 'spring forward' and the first Sunday in April to 'fall back'. Similarly, even New Zealand falls back in the first Sunday in April but the day chosen to spring forward in their case happens to be the last Sunday of September - and not the first Sunday of October as in case of their neighbor.

Even within countries, the Daylight Saving Time norms may differ from one state/province to another. In the United States of America, for instance, the Uniform Time Act of 1966 states that it is not mandatory for the states/territories to follow this concept. (The residents of states like Arizona and Hawaii along with the residents of some US territories follow Standard Time all round the year.) However, if they do choose to follow the same, it is mandatory for them to follow it as per the guidelines put forth by the federal law.
