I suppose I think it's tonight because of this information from the website:
What are the deadlines for application to the SAIS Washington, D.C. campus?
Degree:Fall 2011 Deadline:Spring 2011 Deadline:M.A.January 7No Spring term entryM.I.P.P.February 28October 15Ph.DFebruary 1No Spring term entry
Should the application material be postmarked on the deadline or should it be in by the deadline?
All material, including the GRE or TOEFL scores, must be received by the SAIS Office of Admissions in advance of the published, appropriate deadline.
Is there a late deadline for applications?
No. Completing an application by the January 7th deadline will allow for equal consideration in terms of the admissions and financial aid processes....
So clearly, the statement above refers to the hard copy material that needed to be mailed into the office. But given the emails that have gone out about getting the application in "before the deadline on January 7th", the fact that the website doesn't seem to include any information about a particular time on January 7th, and the fact that NehAgg said he called and they told him midnight (midnight January 7th is technically tonight). That makes me think I have less than three hours to submit, not the 27 hours I'd hoped.
But maybe all of this is just last minute panicking? I'm so burned out with applications I don't know what to think anymore.
