The first Lunar New Year day is similar to the solar new year day.

大年初一与阳历大年初一相似。

A normal solar day is the time it takes the sun to be directly above you again on earth.

正常太阳日是太阳再次位于地球正上方所需的时间。

If we start a solar day and a Sidereal day at the same time, we'd see them slowly diverge throughout the year.

如果我们同时开始太阳日和恒星日，我们会看到它们在一年中慢慢发散。

If you were on the surface of the planet, you would actually have to go around the sun twice to get one full Mercury solar day.

如果你在这颗行星的表面，实际上你必须绕太阳两圈才能有一个完整的水星太阳日。

So in a 24-hour solar day, earth actually has to rotate more than 360 degrees in order to bring the sun directly overhead again.

因此，在 24 小时太阳日中，地球实际上必须自转超过 360 度才能再次将太阳直接带到头顶。

It will guide anyone and everyone through the details of solar, stellar, and standard 24 hour days; how they're related; and how the orbit of the earth affects them.

它将指导任何人和每个人了解太阳、恒星和标准24小时的细节；它们之间的关联以及地球轨道对它们的影响。

Solar days use the sun as a reference point for when " noon" is, but the length of time between when the sun is highest isn't constant - it changes up or down by a minute over the course of the year.

太阳日以太阳作为“正午”的参考点，但太阳何时到达最高点的时间间隔是变动的它在一年周期中的变化幅度为一分钟。
