Daylight saving time could take effect for the last time on Sunday. Amid the federal government debating whether to keep daylight saving time or toss it for good, the clocks are leaping forward an hour yet again.

Daylight saving time begins on March 9. Here's how "springing forward" can affect your physical and mental health.

Daylight saving time begins on Sunday, March 9, meaning most Americans will lose an hour of sleep as we "spring forward."

Daylight saving time runs from the second Sunday in March to the second Sunday in November. Digital clocks will automatically advance one hour at 2 a.m. on March 9.

It's once again time to spring forward this weekend as millions of Americans will change their clocks and get that extra hour of sunlight in the evenings.

Daylight Saving Time was introduced as an attempt to make better use of the natural daylight hours during the longer days of spring and summer. By shifting the clocks forward by one hour in the spring, people experience more daylight in the evening, reducing the need for artificial lighting and potentially saving energy.
