This seems to make the lunar phases more regular than they really
are. In the time between the new moon today & the new moon On Jul
6, i.e., 12 phases, the length between each of the phases is, in
days, 8, 8, 7, 7, 8, 7, 7, 6, 9, 7, 6, and 8. I assume, e.g., that,
by "light growing darker" you mean last quarter to new moon. In that
particular instance there are 7, 6, 8 days in the time frame
mentioned. Sometimes the phase can be as long as nine days or as
short as five days. The time from NM 4/8 to NM 5/8 is 30 days; from
NM 5/8 to NM 6/6 27 days; from NM 6/6 to NM 7/6 30 days. The lunar
phases cannot be used to form regular seven-day weeks.
