: Let D be a directed graph with p vertices and q arcs. A vertex in-magic total labeling (VIMTL) is a bijection f:V(D)∪A(D)→{1,2,…p+q} with the property that for every v∈V(D),f(v)+∑_(u∈I(v))▒〖f((v,u))=M〗, for some constant M. Such labeling is Even if f(V(D))={2,4,6…,2p}.In this paper, we explore the Even Vertex In-magic total labeling (EVIMTL) of some 2-regular directed graphs.
