1953 February 19 On the sixth day of the first month, when does the sun set?

It's six o'clock every February when the sun goes down. Because after beginning of spring, everything wakes up, the spring is full, the time difference between day and night is prolonged, the days are long and the nights are short, it is more convenient for people to work in the fields, and the temperature is slowly rising, so the sun goes down later than in winter. It was spring in February, after six o'clock, and it was dark the next day when the sun went down.
