Thread: Which date?

In my dream journal, the dreams are dated by the date of the evening though I basically have all my dreams after midnight (different day, different date). Would it be smarter to use the date of the morning? How do you do this?

I'm not gonna change this until my current journal gets full (gotta keep up the system)

Just to make this absolutely clear:

You fall asleep the 27th of March. You wake up the 28th of March. You write down your dreams, do you "title" them 27.3. or 28.3.?
