Today's day pillar is 己巳 (ji si), a yin Earth day in the sixty-day cycle. Today is also the solar term 谷雨 (guyu), one of the twenty-four stations of the solar year. The month pillar is 甲辰 (jia chen), governed by the term 清明 (qingming).

谷雨 (guyu), grain rain

谷雨 is the rain that grain needs, the last term of spring, around the twentieth of April.

The name is a piece of farming advice preserved as a calendar entry: this is the rain that decides the crop. Many of the twenty-four terms work this way, which is why they still track the seasons of northern China more exactly than anywhere else.

It is a medial term inside the 辰 (chen) month. No pillar changes here; the month pillar that began at 清明 (qingming) runs through it and only gives way at 立夏 (lixia).

When the daily page shows 谷雨 as the governing term, spring has roughly two weeks left in the calendar's reckoning.
