General Election Dates
Voting in Colorado does not happen on just a single day: it's an election season that starts when ballots are mailed three weeks before Election Day. Ballots will be automatically mailed to registered voters with current addresses on Oct. 10, 2025, and those ballots can be voted and returned as soon as they are received all the way up through Election Day. Election Day in Colorado is technically the last day to vote. If in-person voter services are needed, make a plan to avoid the crowd and lines s VSPC near you before Election Day.
