“Today” will be evaluated in your selected IANA time zone. The UTC announcement remains the auditable source-of-truth anchor.
Treat the counter shown in your OpenAI product as the source of truth for your personal account window.
Why “today” is easy to misread
A timestamp can fall on different dates in UTC, Shanghai, New York and Sydney. A rolling allowance can also behave differently from a one-time global reset. ResetWire stores the original UTC time and then renders it in an IANA time zone so daylight saving and cross-date changes remain visible.

- Check the in-product usage display for your account and plan.
- Look for an official OpenAI status or documentation update.
- Read a first-party post as a signal until the outcome is known.
