When does the Codex usage limit reset?

Your own 5-hour and weekly usage windows in Codex roll forward on their own schedule, tied to your usage. The CLI's /status command is the only place with your actual countdown — this site has no way to see your personal account data.

Separately, OpenAI's Codex team occasionally announces a global reset that clears usage for a wider group of users at once, independent of anyone's individual rolling window. That's the kind of event tracked on this site's Codex history page, where every entry links back to the original announcement.

A script checks public posts from OpenAI Codex lead @thsottiaux roughly every 20 minutes and records anything that reads like a reset announcement. The figure at the top of this guide reflects exactly what has been recorded so far — sourced, dated, and pulled fresh at build time rather than typed in by hand, so it won't go stale the way a hardcoded number would.

1. Run /status in the Codex CLI — that's your personal window, separate from any global reset.
2. Open the Codex history page and look for today's date in the table.
3. If today isn't listed, no global reset has been recorded yet — detection is keyword-based, so a very unusually worded announcement could in principle be missed.

OpenAI hasn't published a fixed schedule for these global resets, and the gaps between them vary a fair amount — some land days apart, others go quiet for weeks. The most current reference is the “Typical gap” figure and 26-week heatmap on the Codex page, both of which update automatically as new announcements come in, rather than a number written into this guide that would drift out of date.
