The scenario here is that quite often there is a requirement to only keep data from a specific start date, or where it should be keeping data for the last N number of years (which is the first day in January).

It is best illustrated by using a working example.
Check out that scenario and how you can use the Semantic Link Labs Python library to resolve it.
