The first represents the month, the second represents the ten digits and single digits of the day, and the fourth represents the day of the week.

Fill in the first cube from March to 65438+February, and write on each side for two months, one is writing straight and the other is writing backwards.

Fill in the remaining spaces of the second cube with 3, 4 and 5 respectively.

Fill in the rest of the third cube with 8, 1, 2.

The fourth is Monday to Friday.

6 here can also mean 9.

Let me put it this way:

The first cube faces:

May

June (backwards)

The second cube: 2, the third cube 4, and the last one is Tuesday.
