<P> Because of Hawaii's tropical latitude, there is not a large variation in daylight length between winter and summer . Advancing the clock in Hawaii would make sunrise times close to 7: 00 a.m. even in June . Most of the inhabited islands are located close to the west end of the Hawaii - Aleutian time zone, but Oahu, Kauai, and Niihau are located more than 7 degrees west of the Hawaii - Aleutian time zone's meridian and should, theoretically, be located in the next time zone to the west . (Until about 1946 Hawaiian standard time was based on longitude 157.5 degrees west rather than 150 degrees .) </P> <P> On April 26, 1933, the Territorial Legislature enacted a bill placing Hawaii on daylight saving time from the last Sunday in April (April 30 in that year) to the last Sunday in September, but the law was repealed three weeks later on May 21, 1933 . During World War II between February 9, 1942 and September 30, 1945, Hawaiian Standard Time was advanced one hour to so - called "Hawaiian War Time," effectively placing the territory on year - round daylight saving time . </P> <P> From 1970 until 2006, most of Indiana in the Eastern Time Zone did not observe daylight saving time, but the entire state started to do so in April 2006 after eight counties in western Indiana were shifted from the Central Time Zone to the Eastern Time Zone . One goal for observing DST was to get more Indiana counties observing the same time zone; formerly, 77 counties observed EST, 5 observed EST / EDT (the EDT usage being unofficial only), and 10 observed CST / CDT . As of 2016, Indiana has 12 counties observing Central Daylight Time while the remaining 80 counties observe Eastern Daylight Time . Those counties observing CST are in two groups: one near or in the Chicago metropolitan area, and the other around Evansville in the southwest corner of the state . </P> <P> In 1967 the Michigan Legislature adopted a statute, Act 6 of the Public Acts of 1967, exempting the state from the observance of DST . The exemption statute was suspended on June 14, 1967, however, when the referendum was invoked . From June 14, 1967 until the last Sunday in October, 1967, Michigan observed DST, and did so in 1968 as well . The exemption statute was submitted to the voters at the General Election held in November 1968, and, in a close vote, the exemption statute was sustained . As a result, Michigan did not observe DST in 1969, 1970, 1971, or 1972 . (Radio station CKLW in Windsor, Ontario, just across the river from Detroit, was popular on both sides of the border and would often give both times on the air, e.g. "It's 4: 30 in Detroit and 5: 30 in Windsor!") In November 1972, an initiative measure, repealing the exemption statute, was approved by the voters . Michigan again observed DST in 1973, and has continued to do so since then . </P>
