Leap year officially was accepted in 45 BC so ruffly (exact years between BC and AD are not known, best guess is 33 years for the age of Christ at death) 2088 years. so if every 4 years there is 1 extra day. Without leap years/days the date today (Dec 15 2010) would be 522 days less than what we accept as the date, or July 8 2009.
See its not December but July. the whole idea behind leap year is to keep us aligned in our seasonal/astronomical date.
I personally think the formula is not exactly correct as it should probably be more like mid November but that's just my theory.
Years ago, most of our economy was based upon the farm. Daylight savings provided additional "Daylight" for those working on the farms, in particular those families with children who assisted on the farm.
Daylight saving time has been in effect in the USA since 1918, although its observance has been inconsistent over the years. The current practice of starting daylight saving time on the second Sunday in March and ending it on the first Sunday in November was established in 2007 with the Energy Policy Act.
Alberta first observed Daylight Saving Time in 1918. The practice was initially implemented during World War I as a way to conserve energy. Over the years, the province has adjusted its approach to Daylight Saving Time, with several changes in policies and observance.
Florida first adopted daylight saving time in 1970 when the Uniform Time Act was enacted, which aimed to standardize the start and end of daylight saving time across the United States. However, the state had previously experimented with daylight saving time during World War II and again in the 1960s. Florida has since continued to observe daylight saving time, with some areas opting out of it in certain years.
Starting in 2007, daylight saving in New Zealand is observed from the last Sunday in September until the first Sunday in April.

Virginia adopted daylight saving time in 1918, following the federal government's implementation during World War I to conserve energy. The state has observed daylight saving time since then, with some adjustments over the years.

Benjamin Franklin suggested the concept of daylight savings time to citizens of Paris to conserve candles by rising earlier to use natural morning sunlight. However daylight savings time as we know it was brought forth by William Willett, who spent much of his life unsuccessfully lobbying for it in London.
Daylight Saving Time (DST) was introduced primarily to make better use of daylight during the longer days of summer. The idea is to shift an hour of daylight from the morning to the evening, thereby conserving energy by reducing the need for artificial lighting. It was first widely implemented during World War I and again in World War II as a wartime measure to save fuel. Over the years, various countries have adopted and modified DST for economic and lifestyle reasons.
Queensland was the first state to reject daylight saving, and as a result, has been subject to many ill-informed jokes and derogatory comments about why Queenslanders rejected daylight saving. It should be noted that Western Australia has also now turned its back on daylight saving, after a trial of several years.
