The deadlines at UVa are November 1st for Early Action and January 1st for Regular Decision. There seem to be more people concerned with the "right time" to submit an application this year. Let me cover the three most popular assumptions.
1. Applications submitted early get "easier" reads and show interest.
I completely understand this thinking since it is true for some schools. There are plenty encouraging very early submission of applications these days. At UVa, we have the same review process for the entire application season. We probably won't notice the date that the application arrived. As for interest, it is not a factor for us.
2. We fill the class during Early Action.
About half of our applicants applied during the early round last year and roughly half the offers went to that group. I'm saying roughly because there's a lot more to the conversation, but suffice it to say we do not fill our class with the Early Action applicants. You can look at unofficial statistics about the admission process using the statistics tag on this blog. Official statistics are published by the Office of Institutional Assessment.
3. Applications submitted around the holidays are read by "jolly" admission officers.
I saw this posted in the UVa forum of a popular college admission message board. When we go into reading mode, we are laser focused on the task in front of us. We realize how important our work is to our applicants and we isolate ourselves from outside influences so we give each file the time it deserves. As a result, we aren't always too jolly around the holidays, but we do feel good about the work we're doing.
In a nutshell, submit your UVa application when you feel it is complete. While I always caution students about last minute submission, there isn't a difference between an application submitted on September 1st and one submitted on November 1st when we read. Don't rush yourselves!

As I wrote this, I got word that our first application for the Class of 2019 was submitted on Saturday, one day after the Common App launched.
