The 540 equal divisions of the octave (540edo), or the 540(-tone) equal temperament (540tet, 540et), divides the octave in 540 equal steps of about 2.22 cents each.

Theory

Since 540 = 2 × 270 and 540 = 45 × 12, it contains 270edo and 12edo as subsets, both belonging to the zeta peak edos, zeta integral edos and zeta gap edos sequences. It is enfactored in the 13-limit, with the same tuning as 270edo, but it makes for a reasonable 17- and 19-limit system, and perhaps beyond. It is, however, no longer consistent in the 15-odd-limit, all because of 15/13 being 1.14 cents sharp of just.
