The comma is used to separate similar words. 2011 is a number and January is 'text'. Therefore no comma is needed. But you would want to use a comma to separate two numbers. Hence January 11, 2011.
January 10, 2011 to January 21, 2014
You really need a comma after the day of the month - January 8, 1947.

Dates can be written in various ways; for example: January 21st, 2011 January 25th, 2011 21st January, 2011 25th January, 2011 January 21, 2011 January 25, 2011 21 January, 2011 25 January, 2011 Or, without the comma, or abbreviated: January 21st 2011 Jan 21st(,) 2011 21st Jan(,) 2011 Jan 21(,) 2011 21 Jan(,) 2011 Or with the day of the week included: Friday, 21st January, 2011 Friday, January 21, 2011 Commas are more routinely used in this format, with, in any case, a comma after the year or after the month/day or day/month if the date is in a sentence, for example: 'We expect to be there on Friday, January 21, 2011, and will notify you later of our expected time of arrival.', or 'We expect to be there on Friday, Jan 21, and will notify you later of our expected time of arrival.', or 'We expect to be there on Jan 21st, and will notify you later of our expected time of arrival.' Dates can be written digitally using dots, dashes or spaces: 1-21-2011 21.1.2011 1 21 2011 21 1 11 and so on And, of course, there are other formats in which dates may be expressed. Whether the year is included doesn't usually affect the way you write the month and day. The only rule is to be consistent throughout the document or letter you are writing: if you write a date one way to begin with, keep to that format throughout. If you are replying to a letter, it is polite to write dates the way your correspondent writes them. In the same way, if you are writing for, for example, a teacher, write dates the way that person writes them or, in response to a question, use the date (and any other formats) used in the question.
No, you don't have to put a comma before at all.
