This campaign will be on my Saturday morning, weekly, with breaks for holidays and vacations. I am in North America in the Pacific time zone, which does (for now) still have daylight savings time which means my time shifts an hour in winter.
Exact start and finish times will depend on the players and their own time zones.
This time slot can actually work with a wide range of locations around globe. Even if it turns out to be middle of the night for you, if you want to commit to that, it's fine with me.
To help visualize how this may work in your time, here's a table assuming 8:00AM to 11:00AM my local time during summer. Actual time and duration may shift a few hours depending on the players (I don't mind starting earlier).
NA Pacific | New York | Berlin |
8:00AM to 11:00AM | 11:00AM to 2:00PM | 5:00PM to 8:00PM |
New York and Berlin are just arbitrary cities in other time zones. Any place/continent/country in the world works if you can make the game time work.
