I flew a trip ZZZ-ZZZ1-ZZZ in which the aircraft was past the due date for the weighing requirement in 14 CFR 135.185. While doing preflight planning I happened to overlook the due date; which was documented by an aircraft status sheet in the aircraft's logbook folder as well as in the aircraft's AFM. I believe the oversight was due to distraction from saturation associated with additional COVID-19 guidelines; limited recency of experience also due to COVID-19; as well as mental saturation due to the additional considerations and extra planning that goes alongside flying into a complicated mountainous terrain airport like ZZZ1.
Pilot reported flying a trip with the aircraft being over due on the CFR 135.185 weighing requirement.
