When will the sun and the moon shine together?

It is a natural phenomenon that the sun and the moon shine together. Generally, it can be seen with the naked eye, but the observation effect is not very good. If you want to look good, you need certain conditions. Do you know when the sun and the moon shine together? See what omen? Let's reveal the constellation knowledge for everyone. When will the sun and the moon shine together? In the first half of the lunar calendar (after the fourth day of the lunar calendar), you can see the moon phase when the sun goes down, from west to east. In the second half of the lunar calendar (before the 27th), you can also see the moon after the sun rises, from the western sky to the eastern sky. The condition that the sun and the moon shine together requires that the sun and the moon be above the horizon at the same time. Theoretically, as long as the atmospheric conditions are good, this phenomenon may occur except the fifteenth day of the lunar calendar. But there is a second condition, that is, the limit magnitude of the sky (the darkest celestial body that can be seen) cannot be too low, so generally speaking, when the sun rises or is about to set, the brightness of the sky can easily meet this condition (even in cities). Seeing omens, people think that the sun and the moon are astronomical wonders, so when the sun and the moon appear together, they often think that auspicious events have taken place in the country and the nation. In fact, in theory, this phenomenon can be seen except on the fifteenth day of the lunar calendar every month. There is a beautiful folklore about the sun and the moon shining together. It is said that the sun god has ten sons, and only the youngest son is kind-hearted and kind-hearted. When the sun god is old and weak, he always takes care of him. At the moment of death, he died with a smile in the brief intersection of eyes and thorn sun. At the same time, I have a hazy memory of my past life, and there is a real and pure light hidden in my subconscious. After the death of the sun god, his sons showed off their light and heat in the sky, and only the thorn sun kept the most dazzling light. Everything on the earth was destroyed by luminous creatures, and then there was the shooting of the sun by Hou Yi. Hou Yi shot nine suns mercilessly before he died. He hesitated when he opened his crossbow and shot at the thorn sun. Where does the sun shine on the earth? His eyes on the earth are as kind as a mother's eyes on her son, as gentle as a child stroking his beloved teddy bear. Hou Yi still gave up. Luna's daughter is called Dark Moon. When the thorn sun and the dark moon first met, the cold eyes of the dark moon and her delicate posture made me feel a dull pain after seeing the thorn sun. He also understood why he unconsciously kept a copy of Light and Heat. This is predestined love in previous lives. Under the careful care of the thorn sun, Dark Moon's eyes are less cold, more gentle, and her figure is more and more lovely. So Thorn Sun and Dark Moon lived happily together. Everything on the earth has always been a peaceful scene. Until God planted love on the earth. Then lovers on earth always complain that each other doesn't love themselves enough. The world is full of grievances. In order to reduce human grievances, the thorn sun and the dark moon hung high in the sky for the first time. Tell people: it's not that he doesn't love you. Your love for each other never stops. You should cherish each other. Later, the thorn sun and the dark moon always appear irregularly in the sky at the same time, warning the lovers. It's just that people are always busy with their own trifles, and there are few opportunities to see the sun and the moon shine together. According to legend, if we can see lovers whose sun and moon are as bright together, we can last forever.
