  The early stage of the Universe is discussed and the time lengths of its
first days are given. If we denote the Hubble time in the zero-gravity limit by
T (approximately 12.16 billion years), and T(n) denotes the length of the n-th
day, then we have the very simple relation T(n)=T/(2n-1). Hence we obtain for
the first days the following lenghts of time: T(1)=T, T(2)=T/3, T(3)=T/5, etc.
