Calendars
Ancient calendars assumed a year of exactly 360 days and a month of 30 days. The addition of five (or six) days to the year did not become necessary until the resumption of agriculture post-Flood. However, Brown suggests that the day and the month were both shortened:


 * 1) Gravitational settling caused the earth to spin faster, thus shortening the day. The Chilean Earthquake of 2010 produced a similar effect&mdash;tiny, but measurable.
 * 2) Five tremendous impacts on the moon, responsible for the "mascons" in Mare Imbrium and elsewhere on what is now the near side, slowed the moon down and caused it to assume a lower orbit with a shorter synodic period.

Results:


 * 1) A day of 1/365.24 year instead of the earlier 1/360 year.
 * 2) A synodic month of about 29.5 (new) days instead of 30 (old) days.

Assumptions:


 * 1) The year did not change in length during the global flood. (That would have required an unknown source of energy. Immanuel Velikovsky's Worlds in Collision theory is not considered tenable.)
 * 2) Creation took place directly on the fall equinox, corresponding to 4004 BC. That is Sunday (or PrimeDay) 1 Ethanim 1 AM--or actually Saturday (Shabbat) 30 Elul 0 AM at 1800 hours. (The Flood did wrench the earth's rotation, causing a temperate region to freeze.) This was also a new moon--dead on.
 * 3) The alteration took place toward the end of Bul 1656 AM and going into Kislev; the impacts must have occurred during the passage of the moon through its new phase.
 * 4) However, Noah, confined as he was aboard the Ark, did not notice this until 370 days later.
