When year ends or some of your other Task/project comes to an end.
Like for me, during my Studies when semester was ending I was more happy for I shall through that notes , that books I shall give to my that friend/junior and I shall be having new books.
New books to study etc.
(Of course important books I still have with me) but extra I was giving away to have new arrangement.
With year only Calender on our wall/table is associated that changes or you bring more changes ?
