Circa January 2024 (date not set): District Level Pre-primary Caucuses (at least 17 days before the primary). National Convention District-level delegates are slated by Presidential Preference.

Participation in New Hampshire's delegate selection process is open to all voters who wish to participate as Democrats. Only Democrats and undeclared (independents) can request a Democratic ballot in the Presidential Preference Primary

12 January 2024: Due to the non compliant 23 January primary, the state is docked from 32 to 10 delegate votes. Breakdown: 15 to 7 district, 5 to 2 at-large, and 3 to 1 pledged PLEO delegates; 5 to 0 voting DNC Members, 2 to 0 voting Senators, and 2 to 0 voting House members. The date of New Hampshire’s first determining step is in conflict with Rules 12.A and 21.C.1.

1 December 2023: Rules and ByLaws Committee Meeting. While the party has received a waiver to hold their primary on 6 February, the 23 January state-run primary date violates party rules. The Committee discussed rule 21.C.1. that states that a candidate cannot receive delegates from a state that violates the timing rules. Candidates cannot campaign in the state, must not put their name on the ballot, and must take action to remove their name from the ballot. Per Rule 12, the Committee regards this as a non-binding advisory primary. Rule 14.G states candidates should not participate in non-binding advisory primaries, also known as a "beauty contest" or "straw poll". Hence, no delegates are allocated by the New Hampshire 23 January state-run primary. Rule 21.C.1. states that when a primary violates party rules, the number of pledged delegates will be reduced by 50% and the unpledged delegates shall not be permitted to vote. When the 50% is applied, and delegate fraction below 0.5 delegates is rounded down to the whole number and when equal to or greater than 0.5 delegate is rounded up to the whole number.

Tuesday 23 January 2024: New Hampshire Non Binding Advisory Primary. Hours reportedly 6:00a-8:00p EST (1100-0100 UTC). Polls must open by 11 AM however most open between 7 AM and 8 AM. NEW HAMPSHIRE permits its 13 cities to keep their polls open until 8 PM EDT by local option- however, as there ARE only 13 cities among New Hampshire's 234 County subdivisions [the 221 "non-cities", of course, being the proverbial New England Town(ship)], the fact is that the vast majority of NH's polls have closed by 7 PM EDT and the networks have no problem considering this hour as the earliest hour of potential projection. Delegate Pledging: Proportional Primary. Voter Eligibility: Modified Primary.
