I want to compare the mean/median of a variable X between 2 independent samples. Variable X is continuous, ranges from <1 week to 32 weeks. The problem is, I have increments of weeks (1, 2, 3, 7, ...32) and then 30% of the data which is <1 week. How should I model this variable, should I assign it a randome value like 0.5 weeks?

It probably doesn't matter what value you assign to the <1 cases if you use a rank-based nonparametric test as are available in PROC NPAR1WAY.
