Beginning of spring Day is the dividing line of a year in the summer calendar, and the neutral spring day in the solar calendar usually falls on February 4th, sometimes on February 5th.
Therefore, the fleeting time can be said to have changed that day in beginning of spring. But sometimes, the fulfillment of Shaqi will be earlier. So it's best to choose a day before beginning of spring, and choose an auspicious day to arrange the settlement.
