Livestream schedule?

As already announced, I'd like to start livestreaming before the end of October. 
My question: on which days at which times would you be able to tune in live? 

I'd like to find the ideal time slots for streaming to as many people as possible.
On weekdays, I'm limited to the European evening (7pm - 11pm CEST, that's 1pm - 5pm EDT, not ideal).
The weekend will probably be the best option.

Anyway, I'm eager to hear your suggestions!
