title: How to handle dates in neo4j
body: <p>I'm an historian of medieval history and I'm trying to code networks between kings, dukes, popes etc. over a period of time of about 50 years (from 1220 to 1270) in medieval Germany. As I'm not a specialist for graph-databases I'm looking for a possibility to handle dates and date-ranges.  </p>
  
  <p>Are there any possibilities to handle over a date-range to an edge so that the edges, which represents a relationship, disappears after e.g. 3 years?</p>
  
  <p>Are there any possibility to ask for relationships who have their date-tag in a date-range?</p>
