^{4}× 13**1053 equal divisions of the octave** (abbreviated **1053edo** or **1053ed2**), also called **1053-tone equal temperament** (**1053tet**) or **1053 equal temperament** (**1053et**) when viewed under a regular temperament perspective, is the tuning system that divides the octave into 1053 equal parts of about 1.14 ¢ each. Each step represents a frequency ratio of 2^{1/1053}, or the 1053rd root of 2.

1053edo is consistent in the 11-odd-limit. It is a very strong 5-limit tuning where it tempers out [1 -27 18⟩ (ennealimma), [91 -12 -31⟩ (astro comma), and [92 -39 -13⟩ (aluminium comma). It supports and gives a good tuning for the quadraennealimmal temperament, as well as the 27th-octave trinealimmal.
