Here is a countdown to the targeted launch time at 8:02 p.m. EDT (00:02 UTC) to save you from having to do timezone math and possibly mess-ups (I let the page create the countdown and triple checked it;). Check it out - it has a rocket:
This is an amazing mission, and I'm really looking forward to following their progress.
I am disappointed however, at casual factual errors being stated by the presenters. They produced a graphic showing that this mission will be targeting an orbit higher than the Hubble. This is correct, for Hubble's current altitude. However, the accompanying commentary then stated Inspiration4 will fly higher than any mission since Apollo. This is not correct. STS-103  a servicing mission by Discovery to the Hubble in 1999, had an apogee of 609km - higher than the planned orbit for this mission.
The same casual error / re-definition of an already accepted term applies to the "all-civilian crew" line. The Ars Technica article  covers this point well; plenty of all non-military space flights have occurred.
Weather is 90% "go" by the way, that is there is only 10% probability of violating weather constraints. You can find the report summary at the page of the Space Force 45th Weather Squadron doing the launch support for that:
