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, loafer in 2013 and spaghetti monster in 2016.
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]}
On September 26, 2015 Chris Cain announced a p444 weekender gun based on a 79glider synthesis, as well as a p451/p457+ glidertoweekender converter.^{[3]}
