The problem there is February 1st isn't always a good release day, say if it's a Saturday. So you'd ship on the 2nd or 3rd sometimes... or sometimes that's a holiday, or there are validate reasons to avoid a period (like the first ~week of July or September). You could try to pick something like the "2nd Wednesday" of the month, but there are still occasions for mid-week holidays and other timing problems related to marketing or external events (other announcements, or world events that would clobber your marketing push). Inevitably you have to plan it anyway, so you might as well do that from the start.
