(1) If the ordinance or resolution is adopted by Council and signed by the Mayor as approving it within the seven day period provided for in Section 2.07 of this Charter, its "date of passage" shall be the date the ordinance or resolution was signed by the Mayor.
(2) If the ordinance or resolution is adopted by Council and returned by the Mayor within the seven day period provided in Section 2.07 of this Charter, without the Mayor signing to approve it or vetoing it, or if the ordinance or resolution is adopted by the Council and the Mayor does not return the ordinance or resolution within the seven day period provided for in Section 2.07 of this Charter, its "date of passage" shall be the last day of said seven day period.
(3) If the ordinance or resolution is adopted by the Council, vetoed by the Mayor and approved by a vote of a least four-fifths of the members of Council upon its reconsideration, as provided in Section 2.07 of this Charter, its "date of passage" shall be the day on which it is considered and approved by the Council.
