In the Northern Hemisphere, the Spring Equinox occurs when the sun crosses the equator, heading north.

在北半球，春分发生在太阳穿过赤道向北时。

That's the one with the sun crossed out.

那就是太阳被划掉的那个。

Spring Equinox occurs when the sun crosses the equator, moving north, bringing longer and warmer days in the Northern Hemisphere and shorter days in the Southern Hemisphere.

春分发生在太阳直射在赤道，并向北移动，给北半球带来更长更温暖的白天，给南半球带来更短的白天。

Instead of being a whole day, the equinox is one very specific moment, when Earth's axis isn't pointing toward or away from the sun at all, which is also when the center of the sun crosses the equator.

昼夜平分点不是一整天，而是一个非常特殊的时刻，它是地轴不指向太阳也不远离太阳的时刻，也是太阳中心穿过赤道的时刻。
