The White House calls a "full lid"—signaling no further events for the president—via pool reports after the final scheduled activity, with calls typically between 4-7 PM ET depending on evening briefings, travel, or unscheduled remarks. For March 30-April 4, trader sentiment hinges on President Biden's public schedule released daily around 7 AM ET, influenced by Easter Sunday (March 31) and the White House Easter Egg Roll on April 1, a major all-day event likely delaying the lid past 6:30 PM. Weekends (March 30) and holidays often see earlier lids due to lighter itineraries at Rehoboth Beach, while weekdays (April 2-4) feature standard policy meetings or campaign stops that could extend into evening. Unforeseen developments like press conferences or crises can push lids later; monitor @PressSec and WhiteHouse.gov for updates.
