§ 150.007 GENERAL RULES OF CONSTRUCTION.
   The following general rules of construction apply to the textual provisions of this chapter:
   (A)   Computation of time. In computing a period of days, the day of the act or event from which the designated period of days begins to run is excluded, and the last day of the period of days is included, unless the last day is not a working day. If the last day of the period is not a working day, the period runs until the end of the next day which is a working day. In computing a period of less than seven days, Saturdays, Sundays, and city holidays are excluded.
   (B)   Internal reference. A reference without further identification to a chapter, division, part, or section is a reference to a chapter, division, part, or section of this Land Development Code. A reference within a particular chapter, division, section, or subsection to an division, section, subsection, or other numbered or lettered divisional unit without further identification is a reference to a unit of the next larger unit of this Land Development Code in which a reference appears. For example, a reference in this division to division (A) is a reference to § 150.007(A).
   (C)   Headings. Section and division headings contained herein are for convenience only and do not govern, limit, modify, or in any manner affect the scope, meaning, or intent of any provision of the Land Development Code.
   (D)   Illustration. In case of any difference of meaning or implication between the text of any provision and any illustration, or table, the text shall control.
   (E)   "Shall", "must", "will", and "may". "Shall", "must", and "will" are always mandatory and not discretionary. "May" is discretionary.
   (F)   Tenses and numbers. Words used in the present tense include the future, and words used in singular include the plural, and the plural the singular, unless the context clearly indicates the contrary.
   (G)   Conjunctions. Unless the context clearly indicates the contrary, conjunctions are interpreted as follows:
      (1)   "And" indicates that all connected items or provisions apply.
      (2)   "Or" indicates that the connected items or provisions may apply singly or in any combination.
      (3)   "Either...or" indicates that the connected items or provisions shall apply singly but not in combination.
