What is daylight saving time?
The DST is the practice of moving clocks forward by one hour during summer months so that daylight lasts longer into evening. Most of North America and Europe follows the custom, while the majority of countries elsewhere do not.
Hawaii, American Samoa, Guam, Puerto Rico, the US Virgin Islands and most of Arizona don’t observe daylight saving time. It’s incumbent to stick with the status quo.
