Why does time change after the equinox?

The change in time after the equinox primarily relates to the transition into daylight saving time (DST) in many regions. The equinox marks the point when day and night are approximately equal, signaling the shift to longer daylight hours. As a result, many areas adjust their clocks forward to maximize evening daylight, which affects how we experience time. This practice, however, does not directly change the passage of time itself but rather our scheduling and perception of it.
