	but Durations ( if right understand ) don't define a reference data when itself starting.

	With this limitations a need to manage two element:

		1) the reference data 

		2) the duration 

	Into Pharo i can operate with only one element  which defines both the departure date that the duration.
	It's very useful when i need to select some element according to the period of membership.

	As advice to proceed to handle this problem?

	I do not want to invent the hot water

	Thanks for any considerations ?
