Labeling dates based on the work week it falls under

Hey, first post! Happy to be a part of this forum.

I have, what should be, a relatively easy question.

So I have a column of dates, let's say column A, that consist of dates that only fall in the work week (Mon-Fri). In column B, I want to say if the date in column A is either hold (1/1/2001), late (any date before today), week (today and any date in the current work week), week +1 (any date in the following work week), week +2 (any date in 2 work weeks from today), week +3, week +4, and future (any date more than 4 work weeks from today).

For example: Let's say today is 4/23 (Thursday)
Col A - Col B
1/1/2001 - Hold
4/22/2015 - Late
4/23/2015 - Week
4/24/2015 - Week
4/27/2015 - Week +1
5/6/2015 - Week +2
5/15/2015 - Week +3
5/18/2015 - Week +4
5/25/2015 - Future

So far I've only been able to figure out how to label Hold. =IF(A2=DATE(2001,1,1),"Hold",""). Can someone help me out with this?

Thank you!!
