24 in release order

About this order

Ten days, and why the Series column is not just "24"

The show counts its seasons as days, and the franchise counts them across three titles. Days 1 to 8 are the original run. Day 9 is Live Another Day, which Wikipedia carries on the main list article as season 9 and numbers 193 to 204, and which is held here as season 9 under its own name so that the Series column says what it was sold as. Day 10 is Legacy, which has a new cast, its own series article, and its own season 1 - Wikipedia's list of 24 episodes stops at Live Another Day and does not count it at all.

Redemption is on the page as a series of its own rather than in a Movies bucket. It is not a feature, and this site's rule that films carry no cross-over flags would have suppressed exactly the thing it exists for: Allison Taylor, Noah Daniels, Jonas Hodges, Iké Dubaku, Benjamin Juma and Edward Vossler all appear there first and continue into Day 7 two months later.

The webisodes are here because of when they went out, not because of what they are

The Rookie's first two seasons ran on the Mondays of Day 6. All six share a date with an episode of 24, and the second season is the one with a time on it - six in the morning, Pacific, against Fox at eight that night. That is why every web and disc release on this page is ranked ahead of the broadcast it shares a day with, which is the call the Supernatural page makes for the Ghostfacers webisodes and the Dexter page for Early Cuts.

The Day 6 Debrief is the exception and sorts last on its day. Its first instalment is Jack being questioned about the finale that aired that evening, and taking release order literally would hand a reader the ending of Day 6 before Day 6 had ended.

Conspiracy has one date and twenty-four films

Wikipedia has the 30 January 2005 launch from a cited report and adds, uncited, that the rest followed at three-day intervals. Wiki 24 dates none of them. IMDb stamps all twenty-four with the launch date, which is what it does when it has no dates rather than a claim that they all appeared at once. All twenty-four sit on the launch date here, in their published order, and the individual dates should be read as unknown. Extrapolating the interval would put the last of them in April 2005 on this page's authority and nobody else's.

Three dates that the sources disagree about

The Rookie's third season is dated 2008 here, from Wiki 24. IMDb dates all six episodes to 2007 while its own series header reads 2007 to 2008 and contradicts it; 17 March 2008 was the Monday the first two seasons had trained the audience to expect, and 17 March 2007 was a Saturday.

Day Zero's first episode is dated 20 May 2007, from Wiki 24. Wikipedia says 21 May, "following the airing of the Season 6 finale"; IMDb says 22 May, and carries only three of the eight episodes at all. One source's whole set was taken rather than a hybrid of three, and episodes 4 to 8 rest on Wiki 24 alone.

Chloe's Arrest reached region 2 on 8 November 2010, five weeks before the American disc on 14 December. The American date is used, which is the rule everywhere on this site.

Wikipedia's own table also gives season 3's eighteenth episode a Sunday, 18 April 2004, with the nineteenth on the Tuesday after it. Two episodes in one week on different nights is unusual enough to be worth flagging, and it has not been checked against a second source.

What the titles say, and two places they were changed

Every episode of the show is titled by the hour it covers, and this page carries them with the day taken off the front. Wikipedia writes season 1 as the bare hour and every season after it with "Day 2:" and so on in front; the Season column already says which day it is, so the prefix was redundant on 192 rows and inconsistent on 24 of them.

Legacy's hours are set in the same style as the nine days before it. Wikipedia writes them as "12:00 Noon – 1:00 PM" where the earlier seasons read "12:00 a.m. – 1:00 a.m.", and one page reading two ways would look like a mistake rather than a distinction.

Two titles look like typos and are not. Live Another Day's finale is "10:00 p.m. – 11:00 a.m." and Legacy's is "11:00 p.m. – 12:00 p.m.". Both finales end on a deliberate twelve-hour jump, both wikis agree, and neither should be corrected.

The cross-over flags, and where the line was drawn

Almost everyone in this franchise appears in more than one of its productions, so the flags needed a line or they would have marked most of the page and told a reader nothing.

A transferring lead is not a guest. Jack Bauer is the lead of the original run, of Redemption, of the Day 6 Debrief and of Live Another Day, so his presence in any of them is not a guest appearance - the same ruling the Dexter page makes about Dexter. The guest star icon is for the others: Tony Almeida arriving in Legacy, Chloe and Morris in Chloe's Arrest, David Palmer and Chloe in the season 5 prequel, Cheng Zhi in the season 6 prequel, and Nina Myers, George Mason, Tony, Jamey Farrell, Teri and Kim in Day Zero.

Direction matters. The season 4 prequel is not flagged for Erin Driscoll and The Raid is not flagged for Eric Carter, because both shorts came out before the seasons those characters belong to and a contemporary audience met them there first.

The story arc icon is on the handovers rather than on everything they lead to. Redemption's plot runs through the whole of Day 7 - every one of its twenty-four episodes mentions Juma, Dubaku or Hodges - and only the two episodes that take the handover carry the flag. Day 7's premiere carries the story impact icon as well, because its summary opens by naming Redemption outright.

Two productions carry no flags at all, which is a finding rather than an oversight. Conspiracy is set during Day 4 and refers to the Heller kidnapping, but no character crosses over and no source places the reference in a particular minute. The Rookie has no 24 regular in it and Wiki 24 says plainly that its timeline against the show was never established.

Chloe was talked about for Legacy and never appeared. Mariana Stiles is named as Edgar Stiles' cousin, which is a name-check rather than a cross-over. Neither is flagged.

What is not here, and what could not be finished

The Indian and Japanese remakes are licensed productions rather than this continuity, so they are not here. Neither are the four revivals that were announced and never made - Legacy's second season, the 2017 anthology, the 2017 legal thriller and the 2018 Jack Bauer origin prequel - and the Howard Gordon revival that was still in development at the end of 2025 with no order, no cast and no date. Nothing in this franchise has released an episode since 17 April 2017.

Five rows have no IMDb link: Day Zero's episodes 4 to 8, which IMDb does not carry. Five have no Wikipedia link: the three DVD prequels, Chloe's Arrest and The Raid, none of which Wikipedia covers anywhere.
