The city elections are on May 12 but less than month from that is the primary election.
If you haven't already registered to vote for the May 29th primary election, the last day will be April 30th.
The first day of early voting in the primary elections will be May 14th.
If for some reason you can't make it out to the polls, you can always apply to get a ballot in the mail.
The last day to apply for that will be May 22nd.
