In computing any period of time prescribed or allowed by these rules, or by the Board, the day of the act, event, or default from which the designated period of time begins to run will not be included. The last day of the period so computed will be included, unless it is a Saturday, a Sunday, or a legal holiday, in which event the period runs until the end of the next day which is not a Saturday, a Sunday, or a legal holiday. When the period of time prescribed or allowed is less than seven days, intervening Saturdays, Sundays, or legal holidays will be excluded in the computation.
