Is the inclusion of the exact date of the commission of the offense mandatory for the validity of the information?

No. Such failure to include the exact date of the commission of the crime does not render defective the information. It remains valid as long as it distinctly states the elements of the offense and the acts or omissions constitutive thereof. The exact date of the commission of a crime is not an essential element of it.

It is only necessary to state the exact date and time of the commission of the offense when the same is an essential ingredient of the crime charged. It is enough to allege that the crime was committed at any time as near to the actual date on which the crime was committed.
