Maine's gay marriage law is set to take effect Saturday, December 29.

Maine voters approved the law on November 6, making it the first state to legalize marriage equality through a citizen-initiated referendum. The win is particularly poignant given that voters in 2009 repealed a marriage law approved by lawmakers.

Gay and lesbian couples might be able to marry on the law's first day even though it falls on a Saturday.

Portland spokeswoman Nicole Clegg said the state's largest city was reviewing extending hours of operation into the weekend.

“There are a number of logistical factors that need to get worked out first,” she told the AP.

Without a waiting period to delay couples, wedding bells could ring on Saturday in some communities.

“This is the moment for which we fought so long and hard,” Betsy Smith, executive director of Equality Maine, said in an email to supporters. “Through a devastating loss in 2009 and then three more years of countless phone calls, hours of walking door-to-door, endless data entry and an election night to be remembered for all time.”
