Abstract
We have proposed a model to obtain the length of the day and month at any geologic time. The day is found to increase by 0.002 sec/century since the seventeenth century. The lengthening of the day is attributed entirely to the increasing gravitational constant () with time that manifested its self in tidal forces. The data obtained are consistent with those found from Palaeontology. The length of the day 4500 million years ago was 6 hours and the synodic month was 56.26 present epoch days.
