Calendar (odd/even) parking regulations are in effect between November 1 and May 1 of each year. The ordinance is only in effect between midnight and 7:00 a.m. When you park your car for the evening, park it on the odd or even side of the street that corresponds with the next day’s date. For example, if you park your vehicle for the night at 10:30 p.m. on December 8, park it on the odd side of the street, because after midnight it will be December 9.
