New player looking for my first Campaign

I am a new player looking for a chance to play my first D&D campaign. I only have one character who is a 1st level Blood Hunter, if you'd like another type of character I can make one. I've played several RPGs like Skyrim and Diablo 3, but my knowledge of D&D is not very big. I can learn well enough and I tend to have online resources open for anything I need to find out quickly. My timezone is PST and I work Monday and Tuesday from 10am-6pm and Thursday through Saturday from 2pm-10pm, though my schedule is constantly subject to change. In addition I prioritize my attention on my girlfriend when she's home, otherwise I am available. She works a teacher's schedule of 8ish to 3ish, depending on the day. I also have a martial arts class from 4-6pm. Essentially my availability is Monday and Tuesday from 8am-9am, Wednesday from 8am-3pm, Thursday and Friday from 8am-1pm.

I am a dm since 1984. Can you play on weekdays 9am EDT?

My timezone is PST, I can play then but only for an hour Mondays and Tuesdays, otherwise the rest is fine.

1h is too short.

Sorry, I work in the morning those days, and I only have an hour at home before I leave.
