Right now, most of the country switches clocks twice a year — springing forward to daylight saving time in March and falling back to standard time in November. This bill would end that switching by making daylight saving time permanent year-round, meaning clocks would stay "sprung forward" all the time, with lighter evenings but darker mornings, especially in winter. States or areas that currently skip daylight saving time altogether, like Arizona (outside the Navajo Nation) and Hawaii, would get to pick which time — the old standard time or the new permanent daylight time — they want to stick with for good.
