Many people do not like Daylight Saving Time because it results in late sunrises. This can be more dangerous for people driving to work early in the morning and for children walking to school in the morning. On the other hand, some people like Daylight Saving Time because it provides more leisure time during daylight hours due to later sunsets. Many of these opinions are dictated by geography. Those living in the eastern regions of their time zones prefer Daylight Saving Time and its later sunsets because they are the first to see the sun rise and set in their time zone Those living in the western regions of their time zones dislike daylight saving time and its later sunrises because they are the last to see the sun rise and set in their time zone. Currently, time zones are centered around a governing meridian with boundaries drawn somewhat arbitrarily between the governing meridian and the governing meridians of the time zones to the east and to the west. A governing meridian is simply the meridian that the sun crosses when the clocks of the respective time zone say 12 noon. When we move our clocks ahead for DST, the time zone essentially becomes governed by the meridian in the center the time zone to the east. Those in the western portions of the their time zones have particularly later sunrises and sunsets when observing DST. For this reason Arizona does not observe DST.
