US Daylight Saving Time History - US Time Change in 2017

2007 New US Daylight Saving Time (DST) begins second Sunday in March and ends first Sunday in November. From 1987 to 2006, US Daylight Saving Time started the first Sunday in April to last Sunday in October. Before 1970, every state is different. Some cities may be different in the same state. Some California, New York, Texas. and Maryland Information can be found in the Book of The Chinese Fortune-Telling Calendar for China & USA. Other Information, See Time Changes in America by Doris Chase Doane. For additional daylight saving time information before 1970, you can find Time Changes in the World by Doris Chase Doane and International Time Tables by Gary Fitzpatrick.

Daylight Saving Time was originally introduced in the US during World War I. The reason is to save energy - electricity. US Daylight Saving Time became a yearly observance in 1966. Later, most areas of Arizona and Hawaii don't observe daylight saving time. These states have more daylight hours than other states. The summer months in Arizona are extremely hot. Arizonians don't want to lose the early morning hours where the temperatures are not too high. California, Texas, Pennsylvania, Wisconsin, and Michigan are all considering adopting standard time permanently.

If you were born during the Daylight Saving Time, your birth certificate will record your birth time using the Daylight Saving Time. Your correct birth hour should subtract one hour. Some years or areas might subtract 30 minutes or two hours. It's required to change the history of time change in the USA.
