Short answer and full answer
When is the key date, and is it official?
This site uses 18 February 2027 as a planning date. It is our arithmetic, 120 days from the record date, not an ISO announcement. The public record shows stage 50.00 dated 15 July 2026 and no publication date, so the date is a planning device only.

This site uses 18 February 2027 as a planning date. It is our arithmetic, 120 days from the record date, not an ISO announcement. The public record shows stage 50.00 dated 15 July 2026 and no publication date, so the date is a planning device only.
The public record shows stage 50.00 dated 15 July 2026 and no date for stage 50.20 or publication. ISO has announced no publication date. The planning date sequences the work in the kit and the plan. It must not be written into a contract as an ISO date. The change watch exists because the date is the fact most likely to move, and the review trigger in the transition has a stage change branch as well as a calendar branch.
Where the answer stops
This answer is written from the public ISO record and the register on this site. The FDIS body is not public, so the answer does not quote it or state a draft clause. It is not legal advice, does not certify and does not decide a question for a particular firm or system.
If the answer turns on a fact about your firm, use the free check or read the practice that names the evidence.
