Weekender is a 2c/7 orthogonal spaceship that was found by David Eppstein on January 12, 2000.^{[1]} On April 27, 2000, Stephen Silver found a tagalong for a pair of weekenders (shown below). At present, n weekenders pulling n1 tagalongs constitute the only known spaceships with speed 2c/7, besides selfsustaining loops of weekender conduits. These were the only known period7 spaceships until the discovery of lobster in 2011 and the loafer in 2013.
Despite the relative simplicity of its components, a glider synthesis for the weekender had been elusive since its discovery. A weekender synthesis was completed on January 25, 2015, 15 years after its discovery (and coincidentally, on a weekend).^{[2]}
