[Chalks] Saaary! Must remember to read through previous postings....

Bit of a long explanation this. Some mumbling and rambling. My assumption begins with some events such as calender months and weeks are subjective 'man-made'. On the moon with on side always in the dark the normal definition of night/day does not apply nor would yesterday,sunsets/dawn, time zones etc.. I've tried to word the question to avoid confusion with as seen from earth events, eg crescent moon, except eclipses.
1. Does it occur on the moon, if you were to live there?
2. Does it occur on earth and on moon?
3. Is it subjective man made??
The more I try to think the more I get confused ;)

[Zooo K] No.
[Tuj] Yes! *An audience member faints, the rest gasp*
[Kim] No.
[Chalky] No. But the right area (see answer to Tuj)
[Kim] No.
[Inkspot] (1) I suppose you could define it on the moon using some sort of astronomic framework. (2) It occurs on the Earth because we have defined it. If we visited the moon, we would just use the Earth system and definition. (3) Taking your definition, yes. The more I try and answer these questions, the more I get confused.

Repetition!
