24
This is a production article written from an out-of-universe perspective
For years in the production of 24, please refer to the production timeline.

The timeline of 24 has never been pinned down. The creative team behind 24 has resisted placing any season in any specific year; moreoever, the few date references given tend to conflict with each other, as well as with real life.

According to Evan Katz, the time frame of 24 is intentionally vague and undefined, with each season effectively taking place in the "perpetual now." The production made a concerted effort to avoid showing dates onscreen; those that do appear — for example, the date visible on a cell phone screen — are usually not coordinated, and sometimes reflect the actual date and time when the scene was filmed.[1] Regardless, each season is stated to take place a certain number of years or months after the previous one, allowing the approximate timeline of events below.
