https://en.wikipedia.org/wiki/Daylight_saving_time_in_the_United_States
|
||
In 1986 Congress enacted P.L. 99-359, amending the Uniform Time Act by changing the beginning of DST from last Sunday in April
|
||
to the first Sunday in April and having the end remain the last Sunday in October.[10]
|
||
These start and end dates were in effect from 1987 to 2006. The time was adjusted at 2:00 a.m. local time.
|
||
|
||
By the Energy Policy Act of 2005, daylight saving time (DST) was extended in the United States beginning in 2007.[20]
|
||
As from that year, DST begins on the second Sunday of March and ends on the first Sunday of November.[21]
|
||
In years when April 1 falls on Monday through Wednesday, these changes result in a DST period that is five weeks longer;
|
||
in all other years the DST period is instead four weeks longer.[22]
|
||
|
||
In the U.S., daylight saving time starts on the second Sunday in March and ends on the first Sunday in November, with the time changes taking place at 2:00 a.m. local time.
|
||
|
||
=> ..1985 last Sunday in April last Sunday in October.
|
||
1986.. first Sunday in April last Sunday in October.
|
||
2005.. second Sunday of March first Sunday of November.
