A.T. Robertson Commentary Mark 14:1

"Now after two days was [the feast of] the passover and the unleavened bread: and the chief priests and the scribes sought how they might take him with subtlety, and kill him:" — Mark 14:1 (ASV)

After two days (μετα δυο ημερας). This was Tuesday evening as we count time (beginning of the Jewish Wednesday). In Mt 26:2 Jesus is reported as naming this same date which would put it our Thursday evening, beginning of the Jewish Friday. The Gospel of John mentions five items that superficially considered seem to contradict this definite date in Mark and Matthew, but which are really in harmony with them. See discussion on Mt 26:17 and my
