when does the time change

The time change usually happens twice a year, in the spring and in the fall. In the United States, the time change happens at 2:00 a.m. local time on the second Sunday in March and the first Sunday in November. During the time change, clocks are moved forward one hour in the spring and backward one hour in the fall. The purpose of the time change is to make the most efficient use of daylight and to conserve energy.

In the spring, the time change results in an extra hour of daylight in the evening, while in the fall, the time change results in an extra hour of darkness in the morning. It is important to note that the time change does not take effect in all countries or regions; for example, Hawaii and much of Arizona do not observe the time change.

The time change is an important event for many people and organizations, as they must adjust their schedules and plan accordingly. For example, many schools and businesses adjust their opening and closing times to accommodate the time change. Additionally, many organizations and businesses inform their customers of the time change and provide instructions on how to adjust their clocks. Overall, the time change allows people to make the most of their day and conserve energy.
