·     The 2nd month of the Haab calendar.

·     Either:

o AT is a logogram whose meaning has been lost, so ihk’at = “black <something>”, or

o AT is being used as a rebus to write the word ihk’at, whose meaning has also been lost (and where the ihk’ does not mean “black”).

Given that ihk’at and chakat are two successive months of the Haab calendar, the former is almost definitely the case, as it’s highly unlikely that there would be two independent words ihk’at and chakat with independent meanings, when ihk’ and chak themselves mean “black” and “red”.
