The day before any day the market is open.  Usually, this is Monday through Thursday and Sunday.  If the market is closed because of holidays, the newsletter will be closed.  Also, sometimes (not very often) there is just nothing new to add and a newsletter does not come out.  If you have not seen one by 11:00 PM PST, that usually means one will not be coming out.  We are up early and in the office well before market open, so sometimes it will come out in the morning if something new happens.  I think that covers all of the cases.
