Longer days—kickstarted by an hour less of sleep—lie ahead for Albania as the clocks “spring forward” this Sunday, March 31, marking the beginning of daylight saving time.

The practice has spurned plenty of debate over the years, as many feel it adds unnecessary disruption to our circadian rhythms. 

In the spring, daylight savings begins, moving an hour of sunlight from the morning to the evenings, allowing people to take advantage of the natural light during the supposedly warmer months.

In the spring, clocks will move forward by an hour at 2 a.m. on the last Sunday in March, making it 3 a.m. and making the day an hour shorter. 

In the fall, clocks jump back an hour at 2 a.m. on the last Sunday in October, making it 1 a.m and making the day an hour longer.  

Roughly a third of the world participates in some form of clock changing, though the exact timeline varies by region.
