In the Decimal 3-Year Calendar, the fundamental grouping of days is not a month or year, but a hectode, which is approximately 100 days, a bit more than a quarter or season – the exact measure would be a hectoday. Three solar years (1095–1096 days), or a kilode, are split into 11 hectodes, so four or five of them contain only 99 days. Eleven such cycles, i.e. 33 years or a myriane, contain exactly 12053 days in 121 hectodes, 47 (ca. 39%) of which have 99 days only. The potentially day left out is counted as 00, the others are 01 through 99, so two digits always suffice. Each hectode is divided into ten week-like decanes, which usually last 10 days (0–9, decaday) accordingly, except for the first one. The English names for the days of the week are preliminary.
