How is this calendar maintained?

A scheduled job re-reads OpenAI’s official deprecation page every week and rewrites this table from it. Entries that cannot be traced to a published source are not shown at all, which is why every row carries a source link. Dates change: providers extend deadlines and occasionally bring them forward, so this page reflects what the vendor documented at the last check, not a prediction.
