'Officially' I believe they are closed on Mondays. As noted in the long piece I posted in Non-Food, fresh bread is available on Thursdays, Fridays, Saturdays and Sundays; on Tuesdays and Wednesdays they are open and one can buy the various packaged and baked goods they have on hand. With regard to Mondays, they are generally closed but on occasion I have seen the 'Open' sign lit, indicating someone is there and if you want to buy something, you're welcome to come in.
The hours are approximate and typically, when all the bread baked on a given day is sold out, they close the shop. On Sundays, they regularly close early (12-2 range). As far as opening time goes, on the days when they are baking, there are obviously people present from the earliest morning and one might be able to catch someone's eye and get in to buy one of the first loaves done soon after it comes out of the oven. On Tuesdays and Wednesdays, when there is no early morning baking, I doubt anyone would be in the shop before 7 or 7:30.
My recommendation is to go on one of the four days a week that the Masis are baking and get there as early as you can, as Rien suggests above. The pizza can sell out early and, depending on the unpredictable nature of retail, so too can the bread on some days. If you're interested in one of the special breads, e.g., the French loaves or the cornbread, ask when you're there or else call about availability.
