Fist-telling fortune

What is the specific method of calculating the number of days in a month with fists?

When making a fist, the joint between the back of the hand and the fingers is protruding. From the index finger, the big moon protrudes, with 365,438+0 days, and the small moon recessed between the index finger and the middle finger has 30 days. The specific date is February. After counting the left hand from 1 to July, continue to count the right hand in the same way and count the left hand from August to 65438+February.

12 has large and small months. Generally, we can see whether the month is big or small from the calendar. (Big month 3 1 day, small month 30 days, normal year February 28 days, leap year 29 days. )

1, the left hand is clenched and the back of the hand is in the opposite direction. At this time, we can see "concave" and "convex" joints.

2. The number of joints protruding from the index finger starts from June 65438+ 10, and a round trip just counts to July, and then starts from August and counts to June 65438+February. Is it inconvenient to raise the big moon and lower the small moon?
