In spring, when Daylight Saving Time starts, clocks move forward one hour. In fall, when Daylight Saving Time ends, clocks move back one hour. Daylight Saving Time is the practice of moving the clock forward by one hour at the beginning of and moving it back one hour in. The aim is to make use of daylight longer into the evening by starting daylight an hour later in the morning. Daylight Saving Time starts on the second Sunday in March of every year and ends on the first Sunday in November. It is observed in all US states except Arizona and Hawaii. The clocks are adjusted at 02:00 am local time, which means the change happens at different times of the night depending on the time zone. The clocks move forward from 02:00 am to 03:00 am at the beginning of DST in spring and back from 02:00 am to 01:00 am at the end in fall. In contrast to North America, Summer Time in Europe is observed from the last Sunday in March to the last Sunday in October. Outside of North America and Europe, the time adjustment is only practised in a very small number of countries, so that only about a quarter of the world's population live in countries that observe Daylight Saving Time. The practice lasted from 1942 to 1945, but was followed by patchwork local use again afterwards. A federal law on DST was enacted in 1966, and it has been in use in various permutations and with a number of adjustments ever since. Many people have difficulties remembering which way the clock moves when the time changes.
