Okay, you've figured out how to display all of the days of the month using two cubes in "Calendar Cubes". Now here's your next challenge:

Spell the months of the year with a letter on each face of three cubes. Use lowercase three-letter English abbreviations for the names of all twelve months (e.g., "jan", "feb", "mar").

cube [1]: j, e, o, r, g, y
cube [2]: c, b, a, l, s, (n/u)
cube [3]: f, m, t, v, (d/p), (n/u)

[1][2][3] - jan, jun, oct
[1][3][2] - jul
[2][1][3] - sep
[2][3][1] - apr, aug, nov
[3][1][2] - feb, dec
[3][2][1] - mar, may
