Looking at purchasing the Haruka Express/ICOCA round trip pass for my KIX-Kyoto transfers. I see the round trip pass is valid for 14 days, but my question is when exactly the 14 days are determined. Specifically, I will be arriving at KIX on the morining of Friday 13 September, and retrning to KIX the evening of Friday 27 September. Would the pass still be valid? Or does Friday 12 count as "Day 1", thus expiring on the 26th? Slightly confused and could use advice!
