(NEXSTAR) - The 2024 presidential election is fast approaching, and in some states, the voter registration deadline is as soon as this week.

Voters in key battlegrounds, including Florida, Arizona, and Georgia, have just days to register, and missing these deadlines could mean losing the opportunity to cast a ballot in what is shaping up to be a pivotal election.

In Louisiana, voters who wish to register in person or by mail have until Monday, Oct. 7. After that, you can register through the GeauxVote Online Registration System until Tuesday, Oct. 15.

Early voting is Oct. 18-29 (excluding Sunday, Oct. 20 and Sunday, Oct. 27) from 8:30 a.m.-6 p.m. On election day, Nov. 5, the polls are open from 6 a.m.-8 p.m.

In states like Alaska and Rhode Island, voter registration must be completed by Sunday, Oct. 6. Similarly, South Carolina has an Oct. 6 deadline for online registration, while the in-person registration deadline is earlier, on Oct. 4.

Looking further ahead, several states will see their voter registration deadlines fall on Monday, Oct. 7. These include important swing states such as Arizona, Florida, and Georgia, along with other states like Indiana, Kentucky, and Montana.

Some states, like Connecticut and California, allow in-person registration up to Election Day, but many others cut off all forms of registration weeks in advance. For example, in Alabama, Pennsylvania, and Colorado, voters must register by mid-to-late October.

Below is a full state-by-state breakdown of voter registration deadlines:
