lag composites

I have a list of specific dates (YYYYMMDD) I'm using in a composite. I can make the composite for this list just fine, but am wondering if there is an easy way to extend the composite backward and forward in time, like from day -5 to day +5, while still compositing around actual dates rather than indices.

Thanks,
Kathy Straub
