A Rubik's cube has six faces, so there are six different colors to work with.
This suggests to me that it's
a base-6 encoding, where each color corresponds to a number from 0-5.
Sanity check: in base 6, a 2-digit number can represent up to 35 in base 10, so 2 digits will be enough for the month and day in base 6. That leaves 5 digits for the year, which can represent up to 7775 base 10. So it's an appropriate number of digits.
So I changed each of the dates into
Base 6 representation.
21/05/2013 becomes 33/05/13153
16/09/1980 becomes 24/13/13100
Then I looked at the pattern of the color blocks.
These patterns fit:
330513153 matches the pattern BBWYGBGYB from the first block;
241313100 matches the pattern ROGBGBGWW from the 2nd block.
Thus the colors represent:
Digits: White = 0, Green = 1, Red = 2, Blue = 3, Orange = 4, Yellow = 5.
Read the pattern from the 3rd block:
ORRWGGRYG = 422011251
Day (base 6) = 42
Month (base 6) = 20
Year (base 6) = 11251
42/20/11251 converted to base 10 is 26/12/1615
So my answer is:
December 26, 1615
I'm not sure the significance of this day, if there is one.
