It aims to utilise natural daylight more effectively, reduce dependence on artificial lighting and provide longer daylight hours during evenings. The practice is followed in several countries, particularly in North America and Europe, but India does not observe it.<\/span><\/p>\r\n<h2><b>Daylight Saving Time Latest News 2026<\/b><\/h2>\r\n<p><b>Daylight Saving Time 2026 <\/b><span style=\"font-weight: 400\">began on Sunday, March 8, in the United States and Canada. It will end on Sunday, November 1, 2026, when clocks will move back one hour at 2:00 AM local time, returning to 1:00 AM. This change marks the beginning of standard time. Most smartphones and computers adjust automatically, while traditional clocks require manual resetting.<\/span><\/p>\r\n<h2><b>What is Daylight Saving Time?<\/b><\/h2>\r\n<p><b>Daylight Saving Time <\/b><span style=\"font-weight: 400\">is a system of adjusting clocks according to seasonal daylight availability. Under this arrangement, clocks move forward by one hour in spring and return to standard time in autumn.<\/span><\/p>\r\n<ul>\r\n\t<li style=\"font-weight: 400\"><b>Daylight Saving Time Meaning with Example: <\/b><span style=\"font-weight: 400\">If the standard time is 6:00 AM, advancing the clock by one hour makes it 7:00 AM.
