After Pearl Harbor, FDR instituted year round
DST for three years. US time zones were aptly
named "War Time." Once Japan surrendered
in 1945, the time zones were relabeled

AS of 2007
The rules for DST changed for the ﬁrst time
in 20 years. George W. Bush extended the
length of DST by about one month, leaving
it in effect 238 days out of the year.
BUT IS IT HELPING?
The extension of DST had little or
no effect on energy in California.
Many individuals still found that the
extra daylight gave them the
chance to have more fun after a

not Worth it
DST is almost always one hour ahead, but history has seen several variants of this,
such as the 30 minute “half-adjustment” and the two hour "double adjustment."
Given its varied past, there is no telling what
will happen with DST in the future. It will likely
continue to change from time to time due to
special events or conditions.
