In both his Gospel and Acts, Luke places the ascension at the end of the day of Jesus' resurrection. There is no difference between Luke's dating of the ascension in his Gospel and that in Acts. The forty days mentioned in Acts 1.3 are viewed by Luke as subsequent to the ascension, not as previous to it. The forty days are not the term fixed for the ascension; they are not linked with the ascension at all. They are linked with the post-Easter, post-ascension appearances. The ascension ought to be regarded as preceding the forty days of Jesus' appearances rather than following them.
