^{2}× 7 × 29**812 equal divisions of the octave** (abbreviated **812edo** or **812ed2**), also called **812-tone equal temperament** (**812tet**) or **812 equal temperament** (**812et**) when viewed under a regular temperament perspective, is the tuning system that divides the octave into 812 equal parts of about 1.48 ¢ each. Each step represents a frequency ratio of 2^{1/812}, or the 812th root of 2.

812edo is a tuning for the copper temperament in the 5-limit, although it has a high error on the 5th harmonic. It is much better considered as a 2.3.11.17 subgroup tuning, where it is strong, with errors of 6% or less.
