Your audience is at work on the holidays everyone else has off
A large part of this metro works a schedule set by a park, a hotel or an airport, which puts both their free hours and their hardest weeks in unusual places.
Peak weeks for the tourism economy are school holidays, spring break and the stretch between Thanksgiving and New Year, which are also the weeks a parenting schedule moves a child. The audience is under the most pressure exactly when an employer can spare them least.
Publishing at nine on a weekday morning reaches an office metro. Here it reaches somebody who came off a shift at midnight. Late evening and the middle of a weekday morning both beat the times a scheduling tool will suggest.
State the reply window in terms that make sense on that clock. A promise to call back tomorrow morning means something different to a parent who will be asleep then, and a missed call from a law firm rarely gets returned.
Keep the material practical rather than pinned to a date on the calendar. Somebody working through a holiday period does not need a post about the holiday. They need the general shape of what a plan usually says about a week they do not control.
