The NASA TV broadcast begins at 2 am Eastern for the 6:11:46 am liftoff.
When astronauts are onboard, it’s a whole different feeling. Follow along here:

The launch pad sits at 28.5 degrees latitude and the launch vehicle's guidance system targets 51.6, which is the orbital inclination of the International Space Station - Crew Dragon’s home for the next six months.
The launch window is instantaneous, so no waiting around for a delay. The backup launch time/date is 5:49 am Friday, then two days off and the next attempt would be the 26th and 27th.
Predawn launches are the best for longer visibility because the sun hasn’t risen for us on the ground, but shines on the rocket and plume brightly.
I believe sunrise is at 6:54 am.
Enjoy!
