2023 equal divisions of the octave (abbreviated 2023edo or 2023ed2), also called 2023-tone equal temperament (2023tet) or 2023 equal temperament (2023et) when viewed under a regular temperament perspective, is the tuning system that divides the octave into 2023 equal parts of about 0.593 ¢ each. Each step represents a frequency ratio of 21/2023, or the 2023rd root of 2.
Theory
2023edo is enfactored in the 5-limit, with the same mapping and commas as 289edo.
If we impose a stricter harmonic approach, and require all errors to be below 25%, the subgroup consisting of first 7 such harmonics for 2023edo is 2.13.17.23.47.61.71.
In the 2023e val, it supports the altierran rank-3 temperament tempering out the schisma and the quartisma.
Prime harmonics

Subsets and supersets
Since 2023 factors as 7 × 172, 2023edo has subset edos 7, 17, 119, and 289.
Other uses
2023edo also supports a high badness 323 & 2023 temperament, which Eliora designated as leaves.
