The '''524 equal divisions of the octave''' (''524edo'''), or the '''524(-tone) equal temperament''' ('''524tet''', '''524et''') when viewed from a [[regular temperament]] perspective, divides the [[octave]] into 524 [[equal]] parts of about 2.29 [[cent]]s each.

524edo is excellent in the 2.7.13.19 subgroup, and good in the no-threes 19-limit. In the 3-limit, it is wise to treat 524edo as a dual-fifth system.

524edo is excellent in the 2.7.13.19 subgroup, and good in the no-threes 19-limit. In the 3-limit, it is wise to treat 524edo as a dual-fifth system. The minor fifth, 306\524 reduces to 153\262, as such, on this val 524edo is contorted.

524 years is the length of a calendar leap week cycle with 93 leap weeks, creating a 93 out of 524 maximum evenness scale, represented by the 93 & 524 temperament. In addition, both 93 and 524 represent well the 13:17:19 harmonics. The corresponding comma list in the 2.7.13.17.19 subgroup is 16807/16796, 157339/157216, 47071232/47045881. Eliora proposes that this temperament be named '''ostara''', after the feast of the spring equinox, which 93\524 leap week rule approximates well. Other spring equinoctial temperaments, such as 41 & 231, 97 & 400, and 52 & 293 already have their identities and names.

In the 13-limit, 524edo tempers out 1001/1000 and 6664/6655.
