Had to look this up this morning since the show gave me two time real time points - the show's final 10 episodes of the year took place in less than two months. They gave us Reagan shot in the 3rd episode - Monday, March 20, 1981 - and one of the scenes in the final episode referenced watching Game 5 of the Stanley Cup finals - Thursday, May 21, 1981. The car chase - a day or two after the Stanley Cup game - was obviously filmed when there were no leaves on the trees, and that would be unusual in late May in DC - except maybe this year. Not really earth-shattering or nitpicking, just something that clicked - partially because of the Star Wars sheets, and this was post Empire.
