<p>I may be missing it, but I see the first dates for FPOP (Aug. 22 for most if not all) and for Orientation (Aug. 26), but when is the first day of classes? I'm not sure if I heard Sept. 1 somewhere or if I just made it up...</p>
<p>First day of classes is September 6th. Other important days can be found on the Academic Calendar: <a href="http://web.mit.edu/registrar/www/calendar0607.html%5B/url%5D">http://web.mit.edu/registrar/www/calendar0607.html</a>.</p>
<p>As a general rule, the first day of classes fall term is the first Wednesday after Labor Day.</p>
