Daylight saving time has been observed nationwide in Mexico beginning in 1996. For municipalities located less than 20 km from the US border, such as Ciudad Juárez, and the entire state of Baja California, it coincides with the longer extended daylight saving period adopted for 2007 in the United States.

Daylight Saving Party


The Daylight Saving Party is a registered political party in Western Australia. The Daylight Saving Party was founded in September 2016 by Wilson Tucker. It was registered as a political party on 29 November 2016. An earlier Daylight Saving Party registration in 2005 was cancelled in 2008 when the Electoral Commissioner found that it did not have at least 500 members. That party fielded one candidate each in five of the six regions in the September 2008 election before being deregistered in November the same year.

Samoa uses as standard time and as daylight saving time, which it observes during summer in the Southern Hemisphere. In 2011, daylight saving time ended on Saturday, 2 April 2011, 04:00 local daylight time and started on Saturday, 24 September 2011, 03:00 local standard time. Due to its location in the South Pacific Ocean, Samoa traditionally did not observe daylight saving time. Initially planned for 2009, the introduction of daylight saving time in Samoa was postponed for one year due to the aftermath of the 2009 Samoa tsunami.

List of States Passing Full-Year Daylight Savings Time


The Uniform Time Act was passed in 1966 to define a uniform observance of time for the whole country. The Act included the setting when to begin and end of daylight saving time. The Uniform Time Act also permits states to choose whether they want to observe daylight saving time or remain on standard time permanently all year without any legislative approval from the federal congress. However, the act does not permit states the option to remain on daylight saving time permanently all year. A change in federal law is necessary to allow states to

Daylight saving time (DST), also daylight savings time or daylight time (United States) and summer time (United Kingdom, European Union, and others), is the practice of advancing clocks during summer months so that evening daylight lasts longer, while sacrificing normal sunrise times. Typically, regions that use daylight saving time adjust clocks forward one hour close to the start of spring and adjust them backward in the autumn.

Daylighting is the practice of placing windows, skylights, other openings, and reflective surfaces so that sunlight (direct or indirect) can provide effective internal lighting. Particular attention is given to daylighting while designing a building when the aim is to maximize visual comfort or to reduce energy use. Energy savings can be achieved from the reduced use of artificial (electric) lighting or from passive solar heating. Artificial lighting energy use can be reduced by simply installing fewer electric lights where daylight is present or by automatically dimming/switching off electric

Several studies have recorded the energy savings due to daylight harvesting. Energy savings for electric lighting in the range of 20-60% are common. Savings are very dependent on the type of space the light harvesting control system is deployed in, and its usage. Clearly, savings can only accrue in spaces with substantial daylight where electric lighting would have been otherwise used. Therefore, daylight

Initially, it applied to the whole country (with an exception in part of 1963); in 1968, it was stopped, and resumed only in 1985, since then with no interruptions; and from 1988 on, it was applied only in part of the country. It started on the first Sunday of November (beginning in 2018) and ended on

This effect should be kept in mind when trying to determine if a file is a duplicate of another, although there are other methods of comparing files for equality (such as using a checksum algorithm). A ready clue is if the time stamps differ by precisely 1 hour. A move to "permanent daylight saving time" (staying on summer hours all year with no time shifts) is sometimes advocated and is currently implemented in some jurisdictions such as Argentina, Belarus, Canada (

In 1967, Arizona and Michigan became the first states to exempt themselves from DST (Michigan would begin observing DST in 1972). In 1972, the act was amended (P.L. 92-267), allowing those states split between time zones to exempt either the entire state or that part of the state lying within a different time zone. The

Others argue that ending daylight saving time will place Alaska as much as five hours from Eastern Daylight Time, making coordination of travel and phone conversations more difficult. Arizona observed DST in 1967 under the Uniform Time Act because the state legislature did not enact an exemption statute that year. In March 1968 the DST exemption statute was enacted

UTC+07:30


UTC+07:30 is an identifier for a time offset from UTC of +07:30. UTC+07:30 was used both as daylight saving time as well as Standard Time later in Malaysia and Singapore. Between 1941 and 1942 before the Japanese occupation, and from 1945 to 1965 after the occupation, Malaysia and Singapore used UTC+07:30 as daylight saving time. It was later in 1965 when Singapore decided to declare UTC+07:30 as its standard time. In December 1981 Malaysian prime minister Mahathir Bin Mohamad announced that Peninsular Malaysia would turn clocks ahead by 30 minutes in order to keep

(The Official Guide says "State law prohibits the observance of "Daylight Saving" time in Kentucky but Anchorage, Louisville and Shelbyville will advance their clocks one hour from Central Standard time for the period April 24 to October 29, inclusive.") In the middle 1960s the airline and other transportation industries lobbied for uniformity of Daylight dates in the United States.

One method of predicting energy savings is to use commercially available software programs, such as TRACE 700 or (freeware) DOE-2, which considers thermal loads. There is an incremental cost to daylight harvesting systems. Dividing this cost by the annual energy savings provides a "simple payback", the number of years for the system to pay for itself. The shorter the calculated payback period, the more likely it is that a building owner will invest

The idea was unpopular, however, and Congress abolished DST after the war, overriding President Woodrow Wilson's veto.

Daylight saving time in Canada


Daylight saving time (DST) is observed in all ten Canadian provinces and three territories. However, there are exceptions within several provinces and the territory of Nunavut, including most of Saskatchewan, which observes Central Standard Time year-round even though the province is in the Mountain Zone, effectively putting it on DST year-round. Under the Canadian Constitution, laws related to timekeeping are a purely provincial or territorial matter. In regions where daylight saving time is used, it commences on the second Sunday of March, and standard

Port Arthur, Ontario, was the first municipality in the world to enact DST, on July 1, 1908. Five Canadian cities, by local ordinance, used daylight saving time before 1918: Brandon, Manitoba and Winnipeg, Manitoba (already in 1916) as well as Halifax, Nova Scotia, Hamilton, Ontario, and Montreal, Quebec.

Hawaii is located in the Hawaii–Aleutian Time Zone and does not observe daylight saving time. Most cable providers in Hawaii carry the west coast feed of television networks, though since Hawaii doesn't use daylight saving time, all programs air three hours earlier than what they were advertised as for a majority of the year. Even when the rest of the country is on standard time, programs air two hours earlier. So from November to March, programs advertised as airing at 8:00 really air at 6:00 in Hawaii. And from

There is also an option in newer versions of Microsoft Outlook to enter the time zone in which an event will happen, but often not in other calendar systems. Calendaring software must also deal with daylight saving time (DST). If, for political reasons, the begin and end dates of daylight saving time are changed, calendar entries should stay the same in local time, even though they may shift in UTC time. In Microsoft Outlook, time stamps are therefore stored and communicated without DST offsets. Hence, an appointment
