§ 20. Day, computation. A number of days specified as a period from a
certain day within which or after or before which an act is authorized
or required to be done means such number of calendar days exclusive of
the calendar day from which the reckoning is made. If such period is a
period of two days, Saturday, Sunday or a public holiday must be
excluded from the reckoning if it is an intervening day between the day
from which the reckoning is made and the last day of the period. In
computing any specified period of time from a specified event, the day
upon which the event happens is deemed the day from which the reckoning
is made. The day from which any specified period of time is reckoned
shall be excluded in making the reckoning.
