There may be more than one deadline
Registration, purchases, gameplay, redemptions and account access can stop on different dates. A headline saying “closes Friday” may omit the date that matters for your request.
Save a factual record
Keep the official notice, the version of the rules, relevant dates, support references and your own request history. Note the stated timezone; do not invent a time if only a date is published.
Use the source calendar
Exit Watch lists dates only when backed by a source. An empty calendar means no confirmed deadlines are currently established in the dataset, not that no operator will exit.
