Why do clocks go forward?

Clocks go forward to start daylight saving time, which shifts an hour of daylight from the morning to the evening so people get lighter evenings. The basic idea is to make better use of natural daylight during the warmer months.

Quick Scoop

When the clocks “spring forward,” the time is usually advanced by one hour. That means sunrise and sunset both happen one hour later by the clock, so evenings stay light for longer.

• Why it exists: To make evenings brighter and better match daylight with after-work or after-school hours.

• What it feels like: You lose one hour of clock time on the night of the change.

• Easy memory trick: “Spring forward, fall back.”

Simple example

If the clock jumps from 1:59 a.m. to 3:00 a.m., the missing hour is what gets “moved” into later daylight in the evening. That’s why the day of the change can feel a bit shorter, while the evening feels brighter.

Bottom line

So, clocks go forward to give more usable daylight in the evening during daylight saving time. It is a timekeeping rule, not the sun actually changing its path.
