Life is rarely smooth sailing, and it is inevitable to encounter some difficulties and adversities. What kind of fortune and good or bad luck will there be in the second month of the lunar calendar? Please pay attention to the special topic of February 2021 of the lunar calendar on Shuimoxiansheng.com!Are the days and nights equal during the Spring Equinox?On the Spring Equinox every year, the length of day and night in the northern and southern hemispheres is equal.Around March 20th of the Gregorian calendar every year, when the sun is at 0° of ecliptic longitude (the vernal equinox), it is the vernal equinox. On this day, the sun shines almost directly on the Earth's equator, and the day and night are almost equal in length everywhere in the world (the refraction of sunlight by the atmosphere and the morning and evening shadows are not taken into account here). After the vernal equinox, the sun's point continues to move from the equator to the northern hemisphere, and the days begin to become longer and the nights shorter in all parts of the northern hemisphere, that is, the day is longer than the night; the days begin to become shorter and the nights shorter in all parts of the southern hemisphere, that is, the day is shorter than the night. Therefore, the Spring Equinox is also called the Shengfen. On the day of the spring equinox, the sun shines directly on the earth's equator. The seasons in the northern and southern hemispheres are opposite. In the northern hemisphere, it is the spring equinox, and in the southern hemisphere, it is the autumnal equinox. At the North and South Poles, on the day of the vernal equinox, the sun stays above the horizon all day. After that, as the sun's direct point continues to move northward, a six-month polar day begins near the North Pole and gradually expands in range; a six-month polar night begins near the South Pole and gradually expands in range. Do the days get longer after the spring equinox?After the vernal equinox, the days in the northern hemisphere are longer than the nights, but they do not start to get longer from the vernal equinox, but from the winter solstice.In addition, in the Northern Hemisphere, the days will become shorter and shorter starting from the summer solstice, but the days will be shorter than the nights starting from the autumnal equinox. Specific reason: On the winter solstice, the sun is directly above the Tropic of Capricorn, and the daytime is the shortest in all parts of the Northern Hemisphere. Then the sun's direct point begins to move northward, and the daytime becomes longer and longer in all parts of the Northern Hemisphere. After the vernal equinox, the sun's direct point moves to the Northern Hemisphere, and the days in the Northern Hemisphere begin to be longer than the nights. On the summer solstice, the sun is directly above the Tropic of Cancer, and the daytime is longest throughout the Northern Hemisphere. Then, the sun's direct point begins to move south, and the daytime becomes shorter and shorter throughout the Northern Hemisphere. After the autumnal equinox, the sun's direct point moves to the southern hemisphere, and the days in the northern hemisphere begin to become shorter than the nights.
