Patriots' Day does not occur on the same calendar date each year.

However, in 1969, Massachusetts changed its observance to the third Monday in April to create a three-day weekend, a practice followed by Maine. Connecticut officially recognized the holiday in 2018.

The MIM-104 Patriot is a surface-to-air missile (SAM) system functioning as a terminal air defense platform. Its primary role is to detect, track, and engage tactical ballistic missiles, cruise missiles, and advanced aircraft. The system is comprised of four main operational components: a phased-array radar set for surveillance and tracking, an Engagement Control Station (ECS) for command and control, mobile launching stations, and the interceptor missiles themselves. Its effectiveness stems from the integration of these elements into a cohesive, networked unit capable of responding to multiple aerial threats simultaneously. The engagement sequence begins when the AN/MPQ-53/65 radar detects a target. This multifunction phased-array radar performs airspace surveillance, target identification, and tracking. Once a threat is identified and prioritized within the Engagement Control Station, a command is issued to fire an interceptor. The missile is launched and guided using a Track-Via-Missile (TVM) system. In this method, the ground radar illuminates the target, and the missile's seeker receives the reflected radar signals. This data is downlinked back to the ECS, which processes it to compute precise guidance commands and uplinks them to the interceptor, directing it for a terminal engagement. The missile's warhead is typically triggered by a proximity fuze to destroy the target via blast fragmentation. ...
