What can I log as XC time?

1) I keep my plane in a hangar at an airport more than 50
nm from the airport nearest my home. I decide to fly it
home for a week (1 hr), and tie it down. I fly locally for
that week (5 hrs), then back to my hangar airport (1 hr).
How much of that can I log as XC time usable for a rating?

2) I decide to take a long multi-day trip. Most days I fly
far more than 50 nm (25 hrs). Some days I fly "locally" to
see the sights and return to the same airport (10 hrs) that
is more than 50 nm from home. Some days I make only a
little progress and land less than 50 nm from the airport of
the previous day, but much farther than 50 nm from my hangar
airport (5hrs). How much of that can I log as XC time
usable for a rating?
