→Lunar months and "weeks"

The lunar element of the Chlouvānem calendar is important in marking the closest equivalent to a week. It should be noted that this division, formerly purely astronomical, is now mostly bureaucratic and does not correspond to astronomical values; therefore solar days and lunar days, as far as the calendar is concerned, are both equal. | The lunar element of the Chlouvānem calendar is important in marking the closest equivalent to a week.

A lunar month ('' | A lunar month (''hulyāsena'') is a fixed 34-day division parallel to the fourteen solar months described above. Every lunar month is divided in ''lānicunih'' (pl. ''lānicuneyai''), which is the "fixed" 32-hour (28<sub>12</sub>) bureaucratic lunar day (as opposed to ''ilēmpārṇam'', the astronomical lunar day of variable length, which varies between 30 ½ and 33 Calemerian hours), which is equivalent to the solar day, and ''lānicuneyai'' are grouped in two periods called ''lānimpeɂila'' (pl. ''lānimpeɂilai''), each one of 17 days, half of the lunar month. The ''lānimpeɂilai'' are the closest equivalent of a "week" in the Chlouvānem calendar; they are astronomically based on lunar phases, and are called respectively ''chlærlīltāvi'' (from new to full moon) and ''līleñchlæryāvi''. | ||
These divisions - the ''lānimpeɂilai'' - take the place of “weeks” for event schedules: the fifth and eleventh days of each lunar phase are half-rest days, while the sixth, twelfth, and seventeenth are full rest days; the first day of the first, fourth, seventh, and tenth lunar months are also full rest days. | These divisions - the ''lānimpeɂilai'' - take the place of “weeks” for event schedules: the fifth and eleventh days of each lunar phase are half-rest days, while the sixth, twelfth, and seventeenth are full rest days; the first day of the first, fourth, seventh, and tenth lunar months are also full rest days. | ||

This procedure, however, gets in the way of the following realignment: | ||

In the second case, every 42 years in even cycles (see below) the last lunar phase skips its twelfth and thirteenth days (as this causes a full rest day to be erased, the eleventh day, normally a half-rest one, becomes a lone full rest day). This has the effect of making the last day of that lunar phase also the last day of both the lunar and the solar years — the exact difference between the lunar and solar year being of 9.7142 days, making a 408-day difference every 42 years. Even cycles are those where the additional lunar day is added 10 times starting from the fourth year; odd cycles those where it is added 11 times starting from the second year. | *
