Hi. Although I've seen a number of questions and answers about this promotion I want some help in clarifying the earliest and latest dates I can use for a Rail journey. 

My pass needs to be activated by 01 June. The pass is for 10 days in 2 months. I want to make my first rail journey on 09 June and the rest of the journeys between 25 June and 08 July. 

Is my first journey on 09 June acceptable for this pass.

Appreciate any help the community can offer.
