Normally there’s only a few days between static fire and launch.
This static fire is also notable because the payload (capsule) was on top. SpaceX hasn’t done that since they had one blow up during a static fire test.

[snip] In the filing on Monday January 28, SpaceX says it is aiming for no earlier than Thursday March 7, 2019 for the launch from Cape Canaveral in Florida... taking the Arabsat-6A spacecraft for Saudi Arabia to geostationary orbit. Weighing 6,000 kilograms (13,000 pounds), this satellite will provide communications services to the Middle East, Africa, and Europe. Rumours suggest that the boosters on this launch could be flown again weeks later on a third Falcon Heavy flight. SpaceX is apparently considering a rapid turnaround of the boosters, having them ready to launch again in 60 days. This will be for the launch of the United States Air Force’s (USAF) Space Test Program 2 (STP-2), launching more than two dozen satellites for the US military. [/snip]
(besides the unmanned test flight of the Crew Dragon, in February a Falcon 9 will send a lunar lander to the Moon for the Israeli company SpaceIL)
