LunaSol Time

Since ancient times, peoples have used both the sun and the moon to tell time and yet Sol and Luna tell time very differently. While Sol tells the very precise time of the atomic clock, Luna tells a fuzzy time due to the dephasing of moon and sun orbital motions.  The precise time of Sol is contrasts with the fuzzy Luna time and we must somehow integrate both ways of telling time.

The length of the second is exactly 9,192,631,770 cycles of the Cs-133 atomic clock hyperfine resonance at 9.2 Ghz and the number of seconds is exactly 86,400, which defines each day. But the  number of days in each lunar cycle varies and the length of a lunar month varies by half a day from 29.3 to 29.8 days. Over an eight solar year cycle of 99 moons, there are 7 lunar years of 14 moons each plus one leap moon to make 99 moons. There are 14 full moons for each lunar year but the lunar and solar years only approximately rephase about once every 8 solar years of 365.25 days each and 7 lunar years of 14 full moons each as the figure shows. this is not the most important issue facing civilization right now...that I give you. It just seems such a crying shame that the simple relationship of 99 moons to 8 solar years does not get much press.

The decay of the Kronos atomic time of the solar day is well known and seems to contrast with the equally well known chaos of the Kairos time of the lunar month. But really, these two time dimensions simply reflect the confusion that comes from the duality of matter and action and the duality of discrete quantum versus continuous classical action.

The near coincidence of the 2018 solstice with a full moon at the minimum of lunation period starts the 99 moon period of 2018-26. The Easter moon on 31mar2018 is moon#4 of this 99 moon cycle and celebrates the birth of Spring as the first full moon following the vernal equinox. The lunations around the moon#99 start always involve more solar and lunar eclipses since the sun and moon spend more time at near angles.
