The practice of fast forwarding the clock with an hour during spring and moving the clock back with an hour during the fall is known as the daylight saving time. Most of the countries in North America and Europe observe this practice. Asian and African countries are known not to practice the act of daylight saving time. Only a few numbers of countries in Oceania and Middle East do practice the daylight saving practice. The article highlights more details about this kind of exercise. Here is a link you can click for more info about DST.
The countries such as the United States observes the practice during the spring and the time is pushed forward with an hour on the second Sunday of March. The exercise ends in the first Sunday of November known as the fallback where the clocks are removed with an hour back to take the standard shape. Traditionally the time used to end on the last Sunday of October, but it was pushed forwards to cater for the Halloween celebration.
The length of the daylight saving time varies from one country to the other. In average, the most country is likely to observe the practice for 6 to 9 months. Most parts of the United States will do keep it for almost seven months and two weeks because of its timing on the second Sunday of March and the ending which is the first Sunday of November.
Most people think that the farmers are the one who pushed for the daylight saving time. The actual origin of the daylight saving time is not well recorded. The reason why a large percentage thought that the idea was from the farmers is that it would improve their ability to manage their farms and also to have increased harvest. History has it that most farmers were against the introduction of the daylight saving time. The farmers argued that the daylight saving time would interfere with the normal operations and that it was wise to have standard time for all the year.
The changing of the time does not mean that the day will get longer or shorter. All that changes is the time to accommodate for the extra light during certain seasons. The earth still takes the regular 24 hours to go around its axis meaning that there are no significant changes in the day.
