Did the Annunciation and Good Friday coincide?

As we know, Good Friday falls on March 25 (2016) this year. In Catholic and Orthodox Churches, March 25 is also the Feast of the Annunciation . A priest friend of mine, told me there was once a popular belief in the Middle Ages that the Annunciation coincided with Passion of Our Lord. Can anyone point out to any other sources that support such a popular belief did in fact exist? I have found two sources that seem to support this idea. The 2nd-century writer Irenaeus of Lyon regarded the conception of Jesus as 25 March coinciding with the Passion . The second piece to support this idea comes from the Liturgical Calendar of the Sarum Rite .One can see on page 3 that Annunciation and Good Friday are on March 25th. The Sarum Rite is a variation of the Roman Liturgy in use in England, up to 1559. **Addendum:** The Roman Martyrology commemorates the Feast of St Dismas on the 25th of March! St Dismas is the traditional name given to the Good Thief, who died on the cross next to Jesus at Golgotha.
