For
Smart-contract developers needing market-hours checks
Worth noticing
The page reports calibration against 8,789 Chainlink rounds and a 99.6% match with the trading week; the contract is explicitly labeled unaudited.

Field notes

The page describes an immutable contract rule based on feed updates rather than a maintained calendar, and links to the deployed contract and tested rules. It lists a 60-second lag at the open and a five-minute overhang after close, with a reported worst case of 19 minutes. Its calibration figures are presented by the project, and the page says the contract has not been audited.
