FAQ
What time does Codex usually reset in UK time (London, GMT/BST)?
Of the 44 Codex resets on record, the busiest hour in UK time (London, GMT/BST) is 00:00 BST (23:00 UTC), with 5 announcements. The chart above shows all 24 hours using the current offset UTC+01:00; it describes when past announcements landed, not when the next one will.
Is the next reset time guaranteed?
No. NEXT EST. is the last official reset plus the median gap of the last 10 resets on record. OpenAI does not announce resets in advance and this site does not promise a time.
Why is my own window different?
Your 5-hour and weekly windows are per account and start from your own first message; they refresh on their own clock. The resets on this page are account-wide announcements by OpenAI. Check your own window with /status.
