How many days are there from beginning of spring to the vernal equinox?

The vernal equinox is the fourth solar term in the "24 solar terms". "The vernal equinox, Yin and Yang. So it's hot and cold day and night. " A word "fen" tells the boundary between day and night, cold and heat. At this time, the longitude of the sun is 0 degrees and the position of the sun is above the equator. It is recorded in the almanac that "the bucket refers to the vernal equinox, which is about Sunday, and the northern and southern hemispheres are equally divided day and night, which is also the half of spring, hence the name vernal equinox." The vernal equinox usually refers to the moment when the sun's apparent yellow meridian is at 0, around February 15 of the lunar calendar (about March 19 ~22 in the Gregorian calendar).

On the first day in this city, I walked out of the airport, took a taxi to the branch office, explained my work, and asked my colleagues to take me to the residence prepared by the company. The environment is very good, I am very satisfied. Put your luggage away. It's still a little after five, so I just want to go out for a walk. I am really familiar with the city of GZ, which has been widened for many years. I have fond memories of this city, and the girl in my heart still lives here. This location is really close to the subway, with many bus stops and many people. I walked to the subway station. In fact, I really don't know where to go, and I'm thinking about whether to look for it before. Just then, a voice sounded, so familiar. I turned around and saw her. She walked two or three meters away from me and greeted a girl in the subway. Say that finish, I turned to talk to the girl behind me. That smile is very sweet. I really want to rush up and hug her, but I dare not. She still hates me, and I guess she won't forgive me. I just stood there and watched their backs disappear in the subway station. It's okay. I was very upset when I watched it. I don't want to go shopping again. I went back to my apartment and thought a lot along the way ... suddenly the company called to have dinner together. The first day, everyone is familiar with it. In fact, everyone in the branch basically knows each other, and we also have contacts in the head office. Seriously, I didn't want to eat this meal, but I was not in the mood. Well, I have to go again. I'm drunk. ...

What if I go to work the next day and my mind is full of her? I've been thinking for a long time in the office. Should I go to see her? How can I explain it to her? Wouldn't it be awkward to meet? Will she meet me?
